Description

FREE FALL SIMULATOR TO SUBMIT SUITABLE ENVIRONMENT VISUAL SIMULATION

The present invention relates to a device simulating free fall as practiced by the parachute by means of a vertical wind tunnel, that is to say means for maintaining substantially stationary at least one free-falling position of person in a vertical air flow upward. More particularly the invention relates to a free fall simulator comprising means for representing an outer simulated visual environment during the simulated free fall.

The training of parachutists free fall to learn and improve the movements and attitudes to be achieved during the freefall phase revealed long-standing need for safe and economic means, independent of weather conditions from the drops of a plane, to enable learning and training in all seasons.

Relatively simple means in which the parachutist hangs on the body and limbs above the ground by means of elastic suspension has been made. These elastic lines are used to place the parachute in certain specific conditions of the fall ensuring the separation of the soil in attitude similar to that of the free fall and retaining the ability to perform movements in particular in the driving or control of a instructor.

Such means, if economic, however, are far from representative of the reality of physical phenomena encountered during the free fall and do not allow the parachutist to feel the effects of the fall or allow him to s properly train control its position during the fall.

The vertical wind tunnels used in aerodynamic research centers have inspired filmmakers freefall simulators. Despite their relatively high costs, these vertical blowers allow, when their power is sufficient to ensure the stationary position of a skydiver free-falling condition in a vertical aerodynamic flow passage in which the air flows from the bottom up the vein and with compatible speeds to maintain stable vertical position of the parachutist, typically 40 m / s to 70 m / s.

Different vertical wind tunnels of this type for fall simulator was designed with characteristics varying depending on the goals of their designers. Thus some blowers have a diameter and a sufficient power to allow the fall of simulating two or three paratroopers simultaneously to drive the figures made during the competition jumps.

Have found examples of such simulators freefall in US patents 3484953 or GB 2094162. These two patents have free fall simulators made following the pattern of veins in aerodynamic wind tunnels closed in which the air accelerated in the vein blower where the change or parachutists, follows a closed path between the output of said vein and its introduction into the same vein after passing through the or propellers which generate the airflow. In these embodiments, the blowers infrastructure are for example made of concrete and fixed due to their dimensions and their masses.

To equip at lower costs skydiving centers and also to make free fall simulators for discovering the sensations of free fall by the public at fairs and other entertainment venues, simulators free falls more construction lightweight, transportable or have been devised.

Examples of such embodiments are given in GB 2062557, which implements a blower architecture aerodynamic vein closed as in the examples mentioned above, or in the patent application WO 83/01380 which operates in open aerodynamic stream, c that is to say in which the air entering the vein is taken from the mass of ambient air and is discharged to the output of the vein in the ambient air at the upper part of the simulator. All these simulators have more or less elaborate means to access the test section, but outside safety nets and padding the walls of the aerodynamic vein in which evolve the paratroopers in training, they do not provide intrinsically the safety of persons performing a simulated jumping.

In WO 83/01380 cited above, the walls of the aerodynamic flow are made of a flexible material such as a fabric or a sheet of a transparent material, but rigid structures are disposed adjacent the flexible walls of the vein aerodynamics which these walls are connected by webs. This provision of the aerodynamic flow and maintaining it does not guarantee that the person moving in free fall state will not hit a rigid structure upon impact against the wall of the flexible aerodynamic stream, much less in case of failure of the flexible wall, such as a tear.

Despite the personal protections are used, including helmets and special suits, incidents and accidents are not uncommon in the use of all these types of simulators fall, even by people who regularly practice free fall.

To further enhance the realism of the simulation, the visual representation means of the environment when jumping have been proposed to be associated with some of these vertical wind tunnels used as simulators free falls. US Patent 5655909 proposes to simulate the visual environment of the parachutist by means of screens on at least a portion of the aerodynamic vein wherein the parachutist evolves when running a simulated jumping. The proposed solution is to replace a portion of the wall of the duct by an image presentation device with multiple displays, sometimes known device in the video wall name. This type of device can generate images on relatively large areas but have the disadvantages of presenting an image with grid lines corresponding to the edges of the screens, to be very heavy and bulky therefore a difficult installation and also place on the wall of the aerodynamic stream rigid structures, such as screens and their necessary supports. The consequences if the person working in the aerodynamic flow hits the wall of said vein, in this case are aggravated by the fact that the visual representation of the environment system makes it virtually impossible to upholstery of the walls of the vein.

The present invention provides a jump simulator both easy to install and implement, offering maximum safety for users and the architecture allows it to have a visual representation of the environment 360 degrees during the simulated free fall.

More particularly, the freefall simulator according to the invention comprises power turbines means for generating an airflow of a speed compatible with the maintenance in a free fall state of at least one person in an aerodynamic vein substantially vertical axis consists of a film of flexible material, resilient and non-resilient, such as a fabric having the form of a tube attached to only two frames positioned at the ends of the tube, the film of flexible material constituting the vein being stretched in the longitudinal direction of the tube solely by means of a holding superstructure which the frames are fixed.

Preferably the wall of the aerodynamic stream is performed in a single developable panel flexible film closed on itself by means of a fixing line for constituting the tube of the aerodynamic vein.

Advantageously said superstructure is of such dimensions that the flexible wall of the aerodynamic stream is sufficiently distant from any rigid part of the superstructure so that the person under simulated fall can not hit a rigid structure in the event of loss of control of its position in the aerodynamic flow.

In a particular embodiment of the invention the means comprise at least one wind turbine engine preferably located in a chamber, at least one propeller and a rectifier-diffuser.

Advantageously, the rectifier-diffuser is located at the upper part of the chamber containing the at least one motor and the superstructure maintaining the aerodynamic vein vertically above and substantially in the axis of the diffuser rectifier.

In a particular embodiment of the invention, the air to be accelerated in the aerodynamic flow enters a chamber containing the at least one motor by at least one opening in a wall of the chamber.

For transport facilities and simplification of assembly and disassembly or simulator, power turbines means are advantageously fixedly installed in all or part of a transport container.

In a particular embodiment of the invention, the film of flexible material constituting the wall of the aerodynamic stream is translucent and allows, serving as screen, the projection by the outer of the vein image visible from the interior of the vein. Advantageously images that can simulate the visual effect of the free fall are projected by at least one sprayer located outside of the duct or by multiple projector to cover a visual field of 360 degrees in a horizontal plane. The headlamps are advantageously fixed to the superstructure maintaining the aerodynamic vein.

In a particular implementation of the simulator, projected images incorporate real-time image of at least one person shot in free fall state in another free fall simulator.

In a particular embodiment, the aerodynamic flow and other elements of the free fall simulator are protected from the weather, and possibly excessive light under the darkness necessary for a good contrast of projected images, by means of coverage such as a tarpaulin or panels, which means advantageously bear on the aerodynamic vein holding superstructure while maintaining the conditions of apertures or air-tightness required for the correct aerodynamic operation of the simulator.

The control and command means are provided to monitor the operation of the free fall simulator and developments of the person in a state of free fall and to act on the operation of the simulator.

A detailed description of one embodiment of the invention is described with reference to the figures which correspond to:

- Figures 1 an overall view of an embodiment of a simulator according to the invention and its main component parts; - Figure 2: view of the WTG power means and cutaway of the chamber having an engine;

- Figure 3 is a perspective view of an aerodynamic flow according to the invention and means for projecting images onto the wall of the aerodynamic stream;

- Figure 4: view of a holding superstructure of the aerodynamic vein and external protection means;

- Figure 5: means illustration associated with the free fall simulator. The detail) shows an example of means of control and monitoring simulator.

The freefall simulator according to the invention comprises WTG power means 1 adapted to provide acceleration of the air in an aerodynamic stream, an aerodynamic vein 2 having dimensions adapted to changes of at least one person in a situation 6 free fall, means 3 for generating simulated or actual images of an external visual environment for the person operating in the aerodynamic flow, means 4 for steering and control of the blower and image generating means, a 5 superstructure capable of maintaining these means and any accessory means as well as supporting means for protection against the external environment.

These various means are assembled in view of a fixed installation of the freefall simulator, which are designed for assembly and disassembly simplified in order to achieve a traveling installation.

In the latter case, said means and said superstructure are made to ensure the portability of the entire simulator for example in one or more containers whose dimensions are compatible with traditional means of transport by road, by rail, by sea or air.

The example given detailed description of a free fall simulator according to the invention is essentially the case of a free fall simulator having the ability to be easily transported for delivery and commissioning simplified service or for use traveling to discover the free fall as many people in the skydiving clubs or in public demonstrations.

The wind turbine power means 1 comprise at least one motor 10 whose power is calculated based on the middle section 23 of the aerodynamic vein 2 and the desired velocity of the vertical flow of air into the vein. This motor or the motors 10, which are electrical or thermal, lead, if necessary through reducing and or bevel gears, not shown, one or more propellers 11 whose characteristics are also established from the characteristics of the aerodynamic vein 2 and the characteristics of the desired airflow. The determination of the total power required and detailed in the notes or propellers characteristics known means for calculating wind tunnels. For a greater autonomy of freefall simulator, preferably is used or heat engines, for example diesel type engines, capable of supplying power of about 1000 kW which are necessary for driving the propellers or 11 of the blower of a simulator according to the invention. The number of helices 11 and engine 10 is selected according to the middle section 23 of the aerodynamic vein 2 and the power of the available engines. Economic criteria may also lead to select smaller engines in larger numbers for example.

The motor or motors 10 of the power turbines means are arranged within a chamber 12, which chamber 12 is adapted to receive at its upper portion 13 the aerodynamic vein or 2. The propellers 11 are mounted with their substantially vertical rotational axes 14 to to generate an airflow 15 directed upwards. Advantageously, air 15 thus accelerated is drawn into the chamber 12 or are located or the motors 10 which improves the cooling of all motors 10 and any reducing agents.

At least one opening 17 is provided in the wall of the chamber 12 to allow the arrival of the air 18 required for operation of the aerodynamic vein 2. In the case of using one or more internal combustion engines, a or fuel tanks 70 are provided to ensure the desired independence to the blower. These tanks 70 and arrival and return fuel hoses are manufactured according to good practice and safety standards. For example, if the simulator is traveling, the fuel reserve is divided into several reservoirs 70 do not exceed a volume of 500 liters per tank, maximum allowed by certain standards for mobile installations, and the storage device 70 are preferably or isolated from the engine 10 to reduce the risk in case of fire starting. In particular means of fire safety and protection against fire (not shown in the figures) are installed as well as requirements in the chamber 12 of the motor or motors.

Above the propeller 11 or is a rectifier-diffuser 19. This rectifier-diffuser 19 is intended to stabilize the airflow 15 or accelerated by the propeller 11 which is particularly turbulent after its passage through the or propellers . Conventionally this rectifier-diffuser 19 is formed with a grid of thin walls of sufficient height so that the flow is stabilized as it passes through.

To facilitate transport, chamber 1 containing the motors 10, or the propellers 11, optionally the rectifier-diffuser 19 and optionally the fuel tank 70 in the case of using thermal engines are preferably installed in one or several containers to the template of road, rail, sea or air. Preferably, this or these containers are adapted to receive elements of other parts of the simulator, after their disassembly, to facilitate transport of the fall simulator.

In a traditional container dimensions or about 3 meters in width, 12 meters in length and 2.6 meters in height, it is thus possible to achieve a room 1 having a length of 4 meters and the width of the container, sufficient to hold the motor or motors 10, or the propellers 11 and the rectifier-diffuser 19. the remaining space is approximately 8 meters on the container length allows the installation or storage during transport other means associated with the simulator .

Above or the propellers 11 and the rectifier-diffuser 19, in the extension thereof, is installed the aerodynamic vein 2 of vertical axis 20 wherein changing the person 6 in conditions of free fall. This vein 2 corresponds to a substantially vertical axis of tube having a bottom end 21 and a top end 22 and preferably substantially cylindrical or slightly conical flared upwards. In the latter preferred embodiment the upper end section 22 is greater than that of the bottom end 21 to create in the aerodynamic vein 2 a negative speed gradient from bottom to top, gradient whose effect is favorable stability on the height position in the vein 2 of the person 6 in free-fall condition. The middle section 23 is preferably substantially circular, but other sections are possible, such as elliptical sections or polygonal cross sections. For installation in a container to road width of the chamber 12, the transverse dimensions to the aerodynamic flow 15 of the bottom section 21 of the duct 2 are limited to about 3 meters. In this case the upper 22 of the duct 2 section, for example, 3.6 meters in its transverse dimensions to the airflow 15 and for example of the order of 4 meters in its working height in the direction of the airflow 15 between the bottom ends 21 and 22 high.

These relatively small size for a fall simulator have the advantage on the one hand to facilitate the realization of a portable wind tunnel and also to participate in the security of the person 6 in simulated fall situation. Indeed in cases where the person 6 in simulated fall situation in the vein incorrectly assumed control of its position substantially at the center of the aerodynamic vein 2, frequent situation with untrained people, this person has 6 not taking into account the free flight distances in the aerodynamic vein 2, the time to acquire a substantial speed relative to the wall 24 of the duct 2 and the protections at its ends 25 high and 26 low, even in case of accelerations, and, thus, the risk of injury from contact with the wall 24 or covers 25, 26 is decreased due to low relative velocities relative to the wall or these protections.

Another important feature of the aerodynamic vein 2 concerns an embodiment thereof. In this free-fall simulator, the side wall 24 of the aerodynamic vein 2 wherein changing the persons 6 in free fall state is performed by means of a film of flexible material. The film, for example a fabric chosen for its strength and dimensional stability, is assembled to form a tube whose length and perimeters at the ends correspond to those desired for the length of the aerodynamic vein 2 and the perimeters of its sections of ends 21, 22. There are today highly resistant and non-elastic tissues in the field of use provided capable of performing the vein such as fabrics made of materials of synthetic fibers such as polyester or aramid, for eg Dacron or Kevlar, widely used for aeronautical applications or for the manufacture of boat sails.

Preferably, the tube forming the wall 24 of the aerodynamic vein 2 is achieved by means of a panel, said film of flexible material developable and closed on itself to bring alongside opposite sides of the panel substantially oriented along a generatrix of the tube. The joined edges are joined by means of a fixing line 27 whose resistance is at least the same level as that of the film of flexible material. Thus, when the joining edges are not assembled, the flexible film material panel can be overhauled and then rolled, for example on a mandrel for storage or transport, without it being created bend could damage the wall 24 or impair its appearance.

Fasteners, not shown, are for example made by means of zippers or laces passing through eyelets or hooks fabrics such as Velcro® or by combinations of these means.

Preferably, at least the lower part of the line of attachment 27, the attachment means are selected to allow opening and fast closing of the wall 24 over a sufficient height to allow the passage of the person 6 before or after a simulated jumping.

Finally, this flexible film material is stretched between two end frames 28, 29 facing said flexible film material the expected shape for the ends, respectively 21, 22, of the aerodynamic vein 2. These frames 28, 29 are formed with means tubes or profiles made of metal or composite materials for example, the shape and the section are sufficient to ensure the necessary rigidity and strength to take voltage efforts in the film of flexible material, including during operation of the simulator. It is essential that there be no rigid structure near the wall 24, and even less to the interior of the aerodynamic vein 2. The tensioning and maintaining the wire constituting the wall 24 of the aerodynamic vein 2 between its two end frames 28, 29 is achieved by connecting said frames 28, 29 to the superstructure 5, the rigid members are remote from the wall 24 of the aerodynamic vein 2 and which maintains the correct position of the frames end 28, 29. the lower frame 28 is fixed above or around the diffuser outlet 19 and so as to force the air flow accelerated by the 15 or propeller 11 to enter the aerodynamic vein 2. the upper frame 29 is fixed to the upper part of the superstructure. Preferably, at least one of the two frames 28, 29 is attached through tensioners, not shown, for example tensioning screw or hydraulic tensioners, which allow to facilitate the mounting of the aerodynamic vein 2 and applying the film of flexible material the desired tensile stresses. In a particular embodiment, elastic means, not shown, are interposed in series with the at least one fixations of the two frames to give managers concerned audits the possibility of slight displacements to limit the forces in the film of flexible material in the event of impact the aerodynamic vein 2 during use. This architecture of the aerodynamic vein 2 allows, in addition to its assembly and relatively easy removal, reduce the risk of serious injury to the person 6 moving in a state of free fall in the event of impact against the wall 24 by avoiding any possibility of contact with a rigid structure. In the choice of resistance of the film of flexible material used is taken into account the stresses induced in said film due to the risk of shock in addition to the mounting tension forces and efforts associated with the aerodynamic flow.

In one embodiment of the invention, another important feature of the wall 24 of the aerodynamic vein 2 is its ability to serve as an image projection screen. In this case the film retained flexible material, in addition to its necessary mechanical characteristics, is translucent so that images projected from outside the aerodynamic stream 2 on the outer face 35 of the vein are visible satisfactorily to the face interior 36 of the wall 24 of the duct 6 by the person in a state of free fall. Some films of flexible materials made from fiber already mentioned synthetic materials have sufficient translucency characteristics, without transparency or excessive opacity to ensure that screen function.

For projecting on the wall 24 of the aerodynamic vein 2 a representation of the visual environment during the simulated drop at least a projector 31 is disposed outside the aerodynamic stream. The simulated environment is according to the desired effect more or less elaborate. For example, the projected image is: a still image of the horizon, or; an image scrolling vertically fixed shapes, for example by means of a disk or a drum carrying the units for projecting and turning behind a projector lens, or;

- images of a film that can match those of a real free fall or imaginary, or;

- real-time computer graphics calculated according to the evolutions of the person in free fall condition, or; a combination of these images.

In the event of use as a public attraction, it is preferable to present attractive images and therefore quite different from those actually collected in a real jump freefall at high altitude. For example it is possible to display images corresponding to a substantially horizontal travel close to the ground to give the printing person to move like a bird.

In a preferred embodiment of the invention, at least three projectors are arranged around the aerodynamic vein to ensure a correct representation of the external environment of 360 ° in the horizontal plane.

To improve the quality of the projected image, depending on the number of projectors 31 and the distance between the projectors 31 and the wall 24 of the aerodynamic vein 2 serving as screen, projectors 31 have the need for correction means the geometry of images, such as targets 32 or anamorphic images shaped front projection by electronic means 33 associated with the projectors 31 in case of using video projectors, to take into account the fact that the screen constituted by the wall 24 of the aerodynamic vein 2 is curved.

This arrangement of the means 3 for projecting images, by placing said means 5 outside the aerodynamic vein 2 and away from the wall 24 of the duct, avoids any risk of contact with hard objects when changes in 6 person in a state of free fall.

In order to ensure the tension of the film of flexible material constituting the aerodynamic vein 2 and the correct position of said vein, a superstructure 5 is disposed above the chamber 12 containing the power of wind turbines means superstructure 1. This ensures the positioning and holding frames 28 and 29 located at the ends of the aerodynamic vein 2. Made e.g. with tubes or profiles 51 made of metal or composite materials it is calculated to withstand the longitudinal forces in the film of flexible material of the aerodynamic vein 2 . All parts of the superstructure 5 are sufficiently separated from the flexible wall 24 of the aerodynamic vein 2 that under no circumstances a person 6 moving in the vein 2 and strikes in the flexible wall 24 can come into contact with rigid parts of the superstructure 5 despite the distortions, but inevitable eligible under these circumstances, the wall 24 of the aerodynamic vein 2. In this superstructure the dimensions 5 takes into account the extreme case of a failure of the flexible wall 24 of the aerodynamic vein 2 and further mattress 52, for example with a foam filling, are if any willing to protect specific areas against which the person 6 in free fall state might have to have contact.

In practice, it is recommended that the distance between the wall 24 of the aerodynamic vein 2 and the uprights of the superstructure 5 is substantially at least equal to the average diameter of the aerodynamic vein 2, or about 3 meters in the embodiment detailed given of the invention.

Advantageously, this superstructure 5 carries means 53 to protect the aerodynamic vein 2 and its associated means 1, 3, 4 to the environment, especially wind and rain when the freefall simulator is not installed in a protected location such as inside a building. In addition, these protective means 53 or other dedicated means are able to create around the aerodynamic vein 2 a relatively dark environment to ensure sufficient contrast of images projected on the translucent walls 24 of the duct 2 when the freefall simulator is equipped with means 3 for representation of the outside visual environment. These protective means 53 consist for example of more or less opaque panels attached to the superstructure or a tarpaulin type of those used for the realization of capitals for public reception and bearing on the superstructure or on 5 secondary structures (not shown).

For operation in wind tunnel closed vein, these protection means 53 supported on the superstructure 5 also covers the chamber 12 in which are mounted the motors 10 or at least the aperture 17 of the chamber 12 through which arrives the air 18 which is accelerated in the aerodynamic vein 2. in this case the space 54 between the wall 24 of the aerodynamic vein 2 and the wall of the protecting means 53 serves as a circulation zone for the return of air between the outlet 22 of the duct and the openings 17 of the engine room. This space is also dimensioned to be of sufficient size so that the air flow circulating in the wind tunnel can be ensured without loss of excessive loads. A receiver adapted in its structure and in its forms to direct the air leaving the aerodynamic flow towards the sides and down around the aerodynamic vein 2 is disposed near the outlet 22 of the duct, at its upper part.

For operation in wind tunnel aerodynamic vein open, these protection means 53 provide protection of the aerodynamic vein 2 and its auxiliary elements 1, 3, 4. In all cases these protection means 53 are made not to interfere with arrival of the outside air to the aperture 17 of the chamber 12 of the motors. Above the aerodynamic vein 2 at the upper part of the protection means 53, one or more apertures are provided for passing the air leaving the aerodynamic vein 2 to the ambient air. This or these openings are preferably surmounted by a receiver 56 to prevent rain or foreign matter, and optionally the light can not penetrate into the protected area of ​​the aerodynamic vein 2 but without impeding the air flow to pass towards the free air.

In a particular embodiment of the invention, the superstructure 5 is designed with sufficient size to enable the headlamps 31 associated with the visual environment of representation of system 3 during freefall be fixed safely and stably with respect to the aerodynamic vein 2. the dimensions of the superstructure 5 are compatible with the positioning of the headlamp 31 at a sufficient distance from the wall 21 of the aerodynamic vein 2 which serves as a projection screen so that this or these projectors 31 operate satisfactorily. The accuracy and stability of the projectors 31 are needed for the projected images are sufficiently stable and the quality of rendering the whole scene particularly in connection areas of images projected by the projectors 31, when several projectors 31 are used.

In one embodiment, the superstructure is constituted by a set of beam 51 equipped with removable connections 57, by bolting end caps (not shown) for example, to ensure the mounting and possibly demounting for transportation of free-fall simulator.

Other means necessary or useful for the operation, monitoring and control of falls associated simulator simulator.

The simulator comprises in particular at least one control station and control 4 which allows for a cockpit of the simulator 41 to monitor the parameters of the simulator and its equipment.

Among the important parameters to be monitored preferably without this list is not exhaustive, are displayed:

- temperatures: c air blower; c cooling water; c oil in motors and gears; powers and output rotation speeds of the motor or motors or on the axis or axes of the or propeller;

- the flow velocities in the aerodynamic flow. The control part comprises at least the means to control the power of the fan to act in particular on the velocity of the flow of air into the aerodynamic flow, speed which differs in particular according to the weight of the person 6 in the maintenance of simulated free-fall, and also comprises the control members of the safety-related devices, such as emergency stop or commands related to fire safety means.

Some of these command and control means can be automated.

Preferably freefall simulator also comprises at least one surveillance camera 42 to observe the person 6 in the aerodynamic vein 2 by means of at least one video monitor 43 near the control and command post. Such a camera 42 is placed outside the portion of the vein 2 or may change the person 60 in free fall state, for example at the top, above a safety net 25 that limits the useful upper position of the aerodynamic stream, or at the bottom, below a thread 26 which limits the useful lower position.

This camera 42 and or other cameras, related or not, if needs also serves to record changes in the person 6 in state of free fall. The parachutist training has the opportunity to review its simulated jump and analyze its shortcomings and corrections attitudes he has to work. In gaming applications people have done a free fall simulation have the ability to keep a record in memory of their experience of skydiving.

In one mode of use in which two or more simulators freefall operate in a coordinated manner on the same site or at distant sites, the images of the person 6 in free fall state in a simulator may be sent in real time the means 3 for representation of the simulated visual environment or other simulators operate in a coordinated manner so that said images are inserted into the projected images in this or these other simulators. Thereby are simulated jumps impressions to several people without the need for a large fall simulator and avoiding the risks of jumping to several people in the same vein blower. In a particular embodiment, other means 7 are associated with the free-fall simulator, for example means 71 for access to the aerodynamic vein 2, a zone 72 for the preparation of persons to the simulated fall, means 73 wait for the public waiting for a simulated fall.
