Description

The utility model relates to the field of training or entertainment equipment, in particular, to devices that simulate the piloting of aircraft. [G09B 9/00, A63G31 / 00].

From the prior art known UNIVERSAL VIRTUAL SIMULATOR [US2020143699, publ. 05/07/2020]. The device contains a capsule installed on a computerized mechanical platform, providing up to six degrees of freedom of movement in real time, and a pilot's seat. The capsule can also be equipped with a control stick, one or more thrust levers and pedals to more closely simulate the real-world pilot experience. Stereo glasses are used to create virtual reality. The invention improves the functionality of the simulator by introducing a virtual avatar with artificial intelligence, which, when flying with a trainee, can imitate the actions of a captain, co-pilot, air traffic controller or instructor. The avatar can also maintain a verbal dialogue with the trainee within the standard pilot communication protocol thesaurus. The device is suitable for any type of aircraft without replacing equipment.

The disadvantages of the analog are:

- high structural complexity of the analogue due to the introduction of a virtual avatar with artificial intelligence, which requires the implementation of additional technical and software solutions, increases the cost of analogue production and imposes additional requirements on the frequency and quality of maintenance;

-Large weight-dimensional indicators of the analogue due to the presence of the capsule in which the user is placed, which significantly limits the scope of application in places with limited space.

Also known from the prior art is ATTRACTION OF SIMULATION OF MOTION [RU114616, publ. 04/10/2012], consisting of a platform rotating around a vertical axis, three supports for a suspension system with retractable rods, a suspension system (cabin) with a passenger seat, a pedal unit, a simulator control system, a 3D screen, a sound system, a central computer, which that the rotating platform is installed on a collapsible base and is made with the possibility of rotation on the base using auxiliary wheels, the central computer and the motor control unit are installed inside the rotating platform, the tubes of the movable rods are mounted on plain bearings, and the drives of the rods are geared motors equipped with a positioning device The suspension system consists of a rigid welded frame made of a rectangular profile.

The disadvantages of the analog are:

-low level of visualization when using the product due to the lack of the possibility of using personal virtual reality tools, instead of which a 3D screen is used;

- low speed of shifting from extreme positions due to the large distance for which the supports are spaced apart.

The closest in technical essence is the PILOT TRAINING SYSTEM BASED ON VIRTUAL REALITY [US2021074173, publ. 03/11/2021], which includes a training terminal integrated with a training pilot's seat, with a seat panel having six degrees of freedom, while the training terminal is configured exclusively to provide and reproduce a simulated flight training environment and output control signals to synchronize the movement of the seat pan with a simulated environment. The system is transportable so that it can be used to conduct flight training at a user-selected and relocatable location. The system may also include an instructor terminal located at the instructor's site. The training location and the instructor's seat can be located remotely. The instructor can provide distance learning to the learner, for example by sending input instructions to the learning terminal over the network to control aspects of the simulated environment.

The main technical problem of the prototype is its low reliability due to the fact that the synchronization of the user's movement with the modulated environment is carried out by means of the pallet, while the static load on the structural elements of the product becomes the higher, the more the pitch and roll angles increase. Considering that during training of pilots most of the time, the installation with the pilot will be in states of large deviation from the longitudinal or transverse axis, the analog design will be subject to additional loads that reduce the reliability of the prototype.

The task of the utility model is to eliminate the shortcomings of the prototype.

The technical result of the claimed utility model is to improve reliability.

The specified technical result is achieved due to the fact that the platform is movable for the flight simulator, containing a base, to which are attached three pusher mechanisms with hinges in the upper part, which connect the pushers with a movable ramp on which the pilot's seat and controls are located, while the pushers are located form the vertices of a triangle between each other, while two pushers are placed beyond the level of the rear edge of the seat base and are located symmetrically relative to the line drawn from the middle of the movable ramp along its length, the third pusher is located on a line drawn from the middle of the movable ramp along its length and is offset to the opposite, relative to two other pushers, the end of the movable ramp.

Implementation of the utility model.

The mobile platform for the flight simulator consists of a rigid base 1, made with the possibility of placing on a horizontal surface. The base 1 in the upper part has a platform for fixing the main elements of the movable platform. In embodiments, the base 1 can be a metal structure made in the form of a multi-beam star, the center of which is a platform for attaching the main elements of the movable platform.

Three pushers 2 are attached to the upper part of the base 1, with a hinge 3 in the upper part of the pusher 2. Each pusher 2 is made with the possibility of reciprocating movement in the vertical plane, during which the lower part of the pusher 2 can be located in the internal volume of the base 1. Geometric arrangement pushers 2 is characterized by the fact that in a general view from above on the upper part of the base 1, the mounting points of the pushers 2 form the vertices of a triangle between themselves (in the embodiments, the mounting points of the pushers 2 form the vertices of an equilateral triangle) (shown in Fig. 5). A movable ramp 4 is attached to the hinges 3. On the front of the movable ramp 4 there is a movable base for fastening the pedal assembly 5. The movable base for fastening the pedal assembly 5 is made with the possibility of movement along the movable ramp 4 due to its profile. At the other end of the movable ramp there is a rigidly fixed base of the chair 6, on top of which the frame of the chair 7 is rigidly fixed. The frame of the chair has a physiological shape to accommodate a person in it. To the left and to the right of the chair frame 7, at the armrest attachment points, there are side platforms for the controls 8.

Two pushers 2 (B and C, see Fig. 5) with hinges 3 in the upper part are located behind the level of the rear edge of the seat base 6 at the rear of the movable ramp 4 symmetrically relative to the line drawn from the middle of the small side of the movable ramp 4 along its length (DD, see. Fig. 5). The third pusher 2 (A see Fig. 5) is located on the line (D-D) drawn from the middle of the small side of the movable ramp 4 along its length and is offset to the opposite, relative to the other two pushers 2, end of the platform frame.

The conventional arrangement of three pushers 2 forms a triangle (ABC) (equilateral in embodiments), the geometric center of which (F) approximately corresponds to the center of gravity of the movable ramp 4 with the pilot's seat (formed by the seat base 6 and the seat frame 7) and a person on board at zero angles tilt.

Due to the ability of each pusher 2 to perform reciprocating movements in the vertical plane independently of the others, and also due to their mutual geometric arrangement relative to each other, changes in the spatial position of the movable ramp 4 with all functional elements located above them, in three planes, are ensured.

Various options for the height positions of the three pushers 2 provide the ability to tilt the movable ramp 4 in the longitudinal axis (positive pitch of about 35 degrees, negative pitch of about 25 degrees), in the transverse axis (roll of about 25 degrees in each direction), and also provides the ability to change it heights.

In an embodiment of the device, the rigid frame of the chair 7 is additionally equipped with soft pillows 9 along the back and along the base of the chair 6, as well as seat belts 10, made with the possibility of fixing a person in the frame of the chair 7. The pedal assembly 11 is connected to the movable base of the pedal assembly 5, which may include rudder and foot brake pedals. On the side platform 8, controls 12 are located, which may include motion control levers, an autopilot control panel, switch blocks, a touchpad, a keyboard, etc. Also at the base of the chair frame 7, between the user's legs there is a control element 12 in the form of a controller for flight simulators. The set of control elements and the pedal assembly 11 form the controls. For the full functioning of the claimed device, the complete set also includes a virtual reality helmet, closed-type headphones and a personal computer (computer), which are connected to the control elements of the platform moving for the flight simulator by means of a power cord and a control cable (not shown in the figure). At the same time, specialized software is installed on a personal computer in advance. Which includes at least one flight simulator program (for example, Flight Simulator) and a peripheral program for the correct delivery of control commands to the platform control.

The mobile platform for the flight simulator is used as follows.

Initially, the platform user is placed on the chair frame 7, over the pillow 9, then the seat belts 10 are fastened, a virtual reality helmet and closed-type headphones are put on. Further, on a personal computer, a flight simulator program is turned on, which, through a peripheral program, transmits control commands to the platform control element. At the same time, the visual effects of the flight simulator program are displayed in the virtual reality helmet, and the audio accompaniment of the flight simulator program takes place in the closed-type headphones. The control element synchronizes the operation of a virtual reality helmet, closed-type headphones and a mobile platform with each other. Further, the platform user carries out a simulation of the aircraft control through the controls 12. There are options for implementation when the platform user does not use the controls, but receives only audiovisual content from the flight simulator program. Simultaneously with the audiovisual effects, the pushers 2 of the movable platform operate by supplying control commands. Depending on the situation that is simulated in the flight simulator program, each of the pushers 2, independently of the others, dynamically changes its position in the vertical plane. A change in the position in the vertical plane of the pushers 2 leads to a change in the spatial position of the movable ramp 4 with all functional elements located above them and the user of the device, in three planes. Depending on the simulated flight situation, various configurations of the spatial position of the pushers 2 in the vertical plane provide the inclination of the movable ramp 4 in the longitudinal axis, the inclination of the movable ramp 4 in the transverse axis and a change in its height.

Consider several options for the spatial position of the pushers 2.

In the case when all three pushers 2 are located at the same level in the vertical plane, the pitch and roll angles are equal to zero (shown in Fig. 1), while the static load on the pushers themselves 2, hinges 3 and base 1 is increased due to the fact that the geometric center of the conditional location of the three pushers 2 approximately corresponds to the center of gravity of the movable ramp 4 with the pilot's seat and a person on board.

In the case when the third pusher 2 is located above or below the pushers 2 located behind the level of the rear edge of the base of the chair 6, the platform is tilted in the vertical plane (shown in Fig. 2). In this case, the static load on the pushers 2, the hinges 3 and the base 1 is significantly reduced due to the fact that the center of gravity of the movable ramp 4 and the functional elements placed on it with the platform user is displaced away from the equilateral triangle formed by the geometry of the pushers 2.

In the case when any two pushers 2 are located above or below the remaining pusher 2, the platform movable in the longitudinal axis is tilted additionally. In this case, the static load on pushers 2, hinges 3 and base 1 is significantly lower than the case when all three pushers 2 are located at the same level in the vertical plane, but slightly higher than the case when the third pusher 2 is located above or below the pushers 2. Center of gravity of the movable frame 4 with functional elements placed on it and the platform user is displaced away from the equilateral triangle formed by the geometry of the pushers 2, but the static load is distributed asymmetrically relative to the line drawn from the middle of the small side of the movable ramp 4 along its length.

The decrease in static load with increasing pitch and roll angles is explained by the principle of inverse stability and is ensured by the described position of the pushers 2.

The technical result of the utility model - increased reliability - is achieved due to the fact that in a general view from above on the upper part of the base 1, the installation sites of the pushers 2 form the vertices of a triangle between themselves. Two pushers 2, the hinges 3 of which are attached to the movable ramp 4, are located behind the rear edge of the seat base 6 in the rear of the movable ramp 4 symmetrically relative to the line drawn from the middle of the small side of the movable ramp 4 along its length. The third pusher 2, the hinge 3 of which is attached to the movable ramp 4, is located on a line drawn from the middle of the small side of the movable ramp 4 along its length and is offset to the opposite (relative to the other two pushers 2) end of the movable ramp 4.

When placing the user of the platform movable for the flight simulator, the arrangement of three pushers 2 forms a triangle, the geometric center of which approximately corresponds to the center of gravity of the movable ramp 4 with the pilot's seat (formed by the base of the seat 6 and the frame of the seat 7) and a person on board at zero tilt angles. Since, in addition to the platform user directly, the most massive element affecting the location of the center of gravity is the base of the chair 6, the removal of two pushers 2 beyond its rear edge allows you to increase the area of the triangle formed by the tops of the pushers 2 and ensure the location of the center of gravity inside it. At the same time, atypical values of the weight and dimensions of the user cannot affect the fact that the center of gravity will be close to the geometric center of the triangle due to the fact that the area of the triangle increases due to the pushers 2 located behind the rear edge of the seat base 6 and the contribution to the total the vector of gravity located on the movable ramp 4, in the area of the triangle, the base of the chair 6 and all functional elements located above it. When using a movable platform for a flight simulator, the above-described arrangement of pushers 2 ensures the implementation of the principle of reverse stability, which guarantees an increase in static stability and significantly reduces the static load on elements such as pushers 2, hinges 3 and base 1 and increases their service life. the fact that the two pushers 2 are located symmetrically, which ensures their uniform wear.

Consider an example of achieving a technical result. The user of the platform is located in the frame of the chair 7, while due to the fact that the two pushers 2, the hinges 3 of which are attached to the movable ramp 4, are located beyond the level of the rear edge of the base of the chair 6 in the rear of the movable ramp 4 symmetrically, relative to the line drawn from the middle of the small side of the movable ramp 4 along its length, the center of gravity of the movable ramp 4 with the pilot's seat and the user, at zero tilt angles, is located as close as possible to the geometric center of the triangle formed by the pushers 2. Most of the time when using the mobile platform, the user spends at significant pitch and roll angles, or close to the maximum possible values. Thus, most often, the movable platform is in states when any two pushers 2 are located above or below the remaining pusher 2, or when the third pusher 2 is located above or below the pushers 2 located under the back of the frame 7 of the pilot's seat. From this it follows that most of the time the center of gravity of the movable ramp 4 and the functional elements located on it with the platform user is located near the geometric center of an equilateral triangle formed by the geometry of the pushers 2. This ensures a decrease in the load on the pushers 2, the hinges 3 and the base 1 and , as a consequence, an increase in static stability, which increases the reliability of the product during its long-term operation and allows to increase the duration of the sessions of using the mobile platform (due to the ability to be in tilt positions for long periods of time). At the same time, an increase in reliability leads to a decrease in the requirements for the precision of actuators, a decrease in energy consumption for movement, an increase in the compactness of the installation, an increase in dynamic characteristics (speed of shifting from extreme positions).

In 2021, the applicant made an industrial and commercial sample of the claimed device, the trial operation of which confirmed the claimed technical result. The increase in reliability over the period of operation of the device was about 80%.
