Definitions

  • the present invention relates to a simulation device intended for training in the maneuvering of shoulder weapons, such as those which are used for launching rockets or self-guided missiles, or in the maneuvering of similar weapons.
  • Simulation devices for shooting training are already known and widely used. They are used for training and instructing shooters by allowing them, indoors or on real ground, to practice aiming a weapon at a target, without actually making use of projectiles.
  • the projectile is a fictitious projectile, a calculator of which makes it possible to define the position in order to compare it with that of the target and to assess the quality of the shot, in particular determining if the aiming is correct to drive the simulated projectile to an impact on the target .
  • These simulation devices are constantly being perfected in order to reproduce the conditions of real shots as well as possible, so that the shooters are not disoriented when they go from training to shooting simulation with real projectiles. However, most attention has been focused to date on tank training or similar shooting positions.
  • a device known according to French patent 2,191,715 filed by the Applicant comprises a weapon with a line of sight which can be oriented by the shooter, optical means for presenting a field of vision to the shooter's observation comprising a shooting range and a target, means for triggering a fictitious projectile shot by the shooter and means for determining the point of impact of the projectile in the plane of the target.
  • Known devices of this type designed for large weapons, such as tank guns, are much less suitable for shoulder weapons.
  • the difference is that in a live fire campaign, the shooter remains in place in front of his weapon in the case of a tank cannon, while in the case of shoulder weapons such as rocket launchers, the shooter immediately releases his weapon the shot started and he can even part with it as quickly as possible by abandoning it.
  • the present invention responds to the concern to better adapt the firing simulation devices of the above kind to training in the maneuvering of rocket launchers for launchers of self-guided missiles or similar weapons, by making it possible to place the operator in conditions very close to those he will encounter in live fire. And for this purpose, it is proposed to provide the simulation device with concealed means controlled to hide the field of vision of the shooter as soon as the shot is started, thus avoiding giving the shooter the annoying habit of staying put to see the result. of his shot and thus being vulnerable to a possible response.
  • the exercises are carried out on a shooting range in which there is a target, generally mobile.
  • the device comprises means for forming a fictitious target appearing in the field of vision of the shooter superimposed on the shooting range.
  • These means may, for example, be of the type described in the patent application filed by the plaintiff on June 12, 1981, under the number 81 11574 and published on December 17, 1982 under the corresponding FR-A-2 507 764 number. to EP-A-0 068 937. They make it possible to visualize in front of the shooter and in front of the instructor a realistic, non-punctual representation of an evolving target.
  • the target is not necessarily unique and the invention applies equally well to exercises on multiple targets.
  • the concealment means are advantageously constituted so that when it is a fictitious target, this target is found in the field of vision of the shooter at the same time as the shooting range, but so as to allow to remain this fictitious target on the instructor station screen when the shooter's field of vision is obscured.
  • the instructor is thus able to assess the result of the shooting based on the position occupied by the point of impact with respect to the fictitious target at the time when the fictitious projectile is supposed to reach the plane of the target. Only the shooting range disappears from his screen when the shooter starts shooting and he can still see the point of impact and the fictitious target which are embedded on its screen by electronic means controlled by the computer.
  • the device makes available to the instructor an index target location, controllable from the instructor station and displayed on the corresponding screen.
  • an index allows the instructor to pursue the target as long as it is visible in the projected image of the shooter's field of vision and then, after the launch of the shot and the occultation, to keep an indication of the position of the target by this index which remains visible on its screen. It is preferable to use an index having a non-punctual contour which can be controlled both in position and in dimensions.
  • Figure 1 is an overview of a simulation device according to the invention used for training in firing rockets from a shoulder anti-tank weapon. This is illustrated by a single rocket launcher tube 6, although the device may include several, depending on the number of shooters to train in the same session. The particular case considered is not restrictive, either, as regards the type of weapon, the tube 6 possibly being more generally a projectile launcher and the projectile possibly being for example a missile as well as a rocket.
  • an optical unit 1 which comprises two parts: an optoelectronic box 11 located inside the launching tube and an optical box 12 placed in front of the shooter's scope 13 and fixed on the internal part of the optoelectronic box 11.
  • a computer 3 comprising logic circuits based on microprocessors and analog interface circuits, makes it possible to manage the optical unit 1, as well as a control desk 21 and a video screen 22 which constitute an instructor station 2. From this position, the instructor organizes the shooting exercises and assesses the results.
  • a battery 4 supplies the supply current at a voltage of 27 V. It also includes electronic circuits which make it possible to recharge it from the network, or to supply the simulator directly from the network.
  • connection cables 5 provide the necessary functional links between the computer and the various elements.
  • FIG. 2 represents a top view of the optical unit 1 integrated in the tube 6.
  • This optical unit 1 comprises various elements which have the function on the one hand of presenting to the shooter's observation, in the scope 13, a field of vision comprising the shooting range, with or without real target, a reticle materializing the line of sight, and possibly a fictitious target, on the other hand to take an image of this field of vision to transmit it to the instructor station.
  • a synthetic image generation device 111 makes it possible to produce fictitious target images under the control of the computer 3.
  • This image generator in the particular case considered here, is of the flying cathode-ray tube type -spot as described in patent application FR-A-2 507 764 filed on behalf of the applicant on June 12, 1981.
  • the successive target images produced on the tube are transmitted to the optical unit 12 and the telescope 13 by a prism with semi-reflecting surface 122 and a semi-reflecting plate 121 of the optical unit 12, both oriented at 45 degrees from the optical path.
  • a video camera 112 is disposed in the optoelectronic box 11, next to the image generator 111, so as to take the picture of the visible optical field of the shooter's scope 13, which is returned to it by the semi-reflecting blade 121 and a prism with a semi-reflecting surface 116.
  • the image is retransmitted by the electronic equipment to be reproduced on the video screen 22 of the instructor station 2.
  • the optoelectronic block also contains a gyroscope 113 which provides information to the computer on the movements which can be printed on the weapon during the operations, so that the computer can compensate for these movements in the calculations.
  • a slope detector 114 also connected to the computer, makes it possible to correct the calculation of the point of impact as a function of the slope.
  • the semi-transparent blade 121 which is located in front of the lens of the telescope 13 and which makes it possible to transmit to the shooter the image of the landscape, by superimposing on it the reflected images coming from the generator. images 111. It also makes it possible to return all of these images, constituting the overall image of the field of vision of the third party, to the video camera 112, through a diaphragm 125, which is automatically adjustable.
  • Two switchable gray filters 124 attenuate the brightness of the landscape.
  • the shooter also sees in the scope 13 a reticle linked to the aiming axis of the weapon, which can either be engraved inside the scope or projected onto it by conventional optical means, or be produced by the image generator 111, under the control of the calculator, and a fictitious target, generated by the device .111 and superimposed on the landscape.
  • the optical unit also comprises, according to the invention, a concealing veil 123, actuated by a rotating electromagnet 126, which can be brought across the optical path to suppress the vision of the landscape in the telescope 13 after the simulated rocket departure.
  • This movement of the web 123 is carried out under the command of an order which is issued from the computer at the time when the shooter triggers the firing by pressing the trigger of his weapon.
  • this concealment device always allows the images coming from the image generator 111 to remain visible to a person looking through the telescope.
  • the arrangement shown is better suited if the target is a real target, which is then eclipsed with the landscape at the time of concealment by the veil 123.
  • the veil is moved to be between the blade 121 and the telescope 13, so that the images from the generator 111, in particular those representing a fictitious target, are hidden from the view of the shooter at the same time as the landscape during the occultation.
  • FIG. 2 shows a windscreen 127, placed in front of the optical unit 12. It is useful in the case of indoor training. Indeed, while in the present description, we have rather referred to training outside, in front of a real shooting range, the same device can be used, under similar conditions, for indoor operation.
  • the shooting range is then constituted by a landscape image projected into the shooter's field of vision. These may for example be fixed images projected from devices in the case where the target is a so-called fictitious target formed elsewhere, or images projected from a film depicting a moving target moving on a fixed ground, the operating mode then being that of a so-called real target training.
  • this computer receives information, mainly from the launching or triggering device of the shot 14, from a device for controlling the generation of a fictitious target 15, available to the instructor, and from a piloting device. index 16 whose usefulness will appear later. It also receives synchronization signals from an electronic video control unit 17, which manages the operation of the camera 112 and adds the video signals received from the camera and the computer to transmit them to the video monitor 18 controlling the visualization on instructor station screen. More accessory bodies whose information is also involved in the calculations have not been shown.
  • the computer emits orders, as has already been explained, mainly in the direction of the image generator 111, which is shown with its cathode ray tube 19 and the current supply (20) at very high voltage of the latter, and in the direction of the concealment device 23, which comprises the web 123 and its drive motor 126. It also produces video overlay signals, which are transmitted to the electronic assembly 17 ' for viewing the corresponding information on the screen 22 of the instructor station.
  • the computer 3 determines, mainly as a function of previously recorded characteristics of the simulated projectile, the distance from the target and the other parameters mentioned, what would be the point of impact of this pojectile in the plane of the target.
  • FIG. 4 shows the indications which are displayed on the instructor's screen under the control of the overlay signals.
  • the fictitious target 43 which appears there, in the case of an operation with a fictitious target, retransmitted by the camera 112 of the image generator 11.
  • the overlay signals contain the information necessary for viewing 'a reticle 41, identical to that which is presented to the viewer of the shooter and linked like him to the line of sight 45, with an index 44 that the instructor determines, in the form of a variable rectangle in position and in dimensions, in the case of operation with an actual target, and an impact cross 42 characterizing the position of the point of impact determined by the computer.
  • a first part of the desk 21 allows the instructor, after the power up (controlled on the computer), to choose between three functions, depending on whether he presses a key "initialization 211, a key” dummy target 212, a key “Real target” 213 .
  • the instructor first chooses the "initialization” key 211, because he must ensure that the harmonization of the origins is correct.
  • the origins or axes of reference for the generation of a fictitious target and the video overlay of the aiming reticle must be confused with the origin of the reticle of the shooter's scope.
  • the instructor uses zone 219 of the control console which allows him, by acting on the potentiometer buttons grouped by three, to first align with the reticle of the telescope of the shooter a reference cross generated by the simulator, centered on a reference axis, then align the crosshairs on the screen with the cross.
  • the three potentiometers of each group allow to move the corresponding image respectively in X, in Y and in rotation (fig. 4).
  • the instructor has part 218 of the desk, which allows him to record the parameters of several fictitious targets before the instruction sessions, namely for example, for each target: a number landmark, the distance d of the target at its appearance, its speed, its orientation in space relative to the horizontal and vertical directions, its position in X and in Y compared to the center of the field (always at the time of its appearance ), the slope of the terrain on which it operates, its brightness. It is also possible for him to modify the recorded linear trajectory of a given target, during exercise, by action in real time on a control stick 215 which makes it possible to modify the orientation of the target and to vary its speed. .
  • Part 214 of the desk is used in conjunction with the control stick 215 when the instructor has chosen the operating mode on real target.
  • the computer In this operating mode, the computer generates the rectangular index 44 on the video screen and the instructor brings this index superimposed on the target (which he observes on the landscape retransmitted by the camera) by means of the control stick 215
  • potentiometers 216 and 217 At the same time, by acting on potentiometers 216 and 217 according to the height of the target and its width, it adjusts the size of the index so that it corresponds to the dimensions of the target.
  • the instructor pursues the target until the start of the shot, which allows the computer to determine by the evolution of the magnitude, the position and the speed of the index, the distance, the position, the target's speed and direction of movement when the shot was fired.
  • FIGS. 5a, 5b, 5c show in successive stages, on the left, what the shooter sees in the scope, on the right what appears on the instructor's screen.
  • the instructor indicates to the shooter the position of appearance of the target (for example: tank at the edge of the grove on the right).
  • the shooter prepares his weapon and directs it to the designated location.
  • the instructor when he considers that the shooter is targeting the indicated area, decides on the departure of the target, by causing the generation of a fictitious target whose parameters he has previously recorded (fig.5a).
  • a fictitious target whose parameters he has previously recorded (fig.5a).
  • a fictitious target whose parameters he has previously recorded
  • the shooter points his weapon (fig. 5b)
  • the instructor appreciates his work by means of the telescopic reticle reproduced on the video monitor.
  • the shooter orders the firing of the fictitious rocket.
  • the triggering of the shot instantly causes the movement of the concealment veil of the optical unit, which then obstructs the vision of the landscape for the shooter and the instructor, and even that of the fictitious target for the shooter in the case shown (fig. 5c ).
  • the shooter then puts down his weapon and moves away, then joins the instructor in front of the video screen to assess the result of the shot. They can see there the inlaid aiming reticle 41, the fictitious target 43, whose position is frozen at the instant of launching of the firing increased by the simulated travel time of the rocket, and the impact cross 42 representing the point d 'impact.
  • the operation is essentially the same except that the target will disappear from the instructor's screen with the landscape.
  • the computer generates the index 44 which will allow the instructor to pursue the real target, by means of the piloting stick, until the moment when the triggering of the shot causes the occultation. , and thus indicate to the computer the position of the target and the parameters of its evolution.
  • the computer considers the speed of the target as constant during the path of the fictitious projectile.
  • the instructor compares the position of the index finger 44 with the position of the cross 42 symbolizing the impact.
