Definitions

  • the invention relates to a system for conducting a ground-to-ground firing of a projectile at a mobile target, and in particular, cannon fire from a tank.
  • the French patent document FR-A-2 440 537 discloses a fire control system which avoids this use of the turret.
  • This system includes a sighting device and a rangefinder to determine the position of the goal and, a computer which receives signals, representing ballistic parameters and the position of the goal, for the calculation of the signals of control of shooting intended for the control mechanisms of barrel orientation.
  • the optical sighting device superimposes the field of observation and a reticle constituted by a grid moved at a uniform speed manually adjustable.
  • the rangefinder makes it possible to determine the distance from the goal which is in the field of observation.
  • the operator pursues by adjusting the speed of movement of the grid equal to that lateral to the goal.
  • the lateral speed of displacement of the goal is then known by the computer as well as the other data necessary for shooting, and this while keeping the turret immobile.
  • An object of the invention is to determine a simple, rapid and precise procedure for orienting the barrel for shooting, taking account of the lateral displacement of the target, this procedure also making it possible to simplify the intervention of the operator.
  • a feature of the invention is to replace the aforementioned manual tracking by operating differently, the reticle being moved at a given time by a known amount relative to the goal and according to the direction of movement thereof, then returning to uniform speed towards its initial position. The operator only has to appreciate the moment when the reticle coincides again with the goal. The measurement of the time elapsed for this operation allows the computer to measure using the ballistic parameters and the distance, the direction of the shot.
  • Another feature of the invention is to advantageously use television equipment present on the tank to constitute the aiming device and simplify the equipment.
  • a ground-to-ground firing control system for a barrel which can be oriented in elevation and in bearing, comprising a sighting device for observing the field of observation and for viewing a reticle whose initial position corresponds in the direction of the aiming of the cannon and which is made to coincide with the aim to be reached, a telemetry device for the measurement of the distance separating the aim of the cannon, additional sensor devices for the measurement of various ballistic parameters, means of manual control to produce a movement of the reticle which takes account of lateral movement of the goal, and management and calculation means receiving the distance data and the ballistic parameters and also taking account of the movement of the reticle to calculate the aiming signals of firing of the cannon in the direction of the future goal.
  • the manual control means are connected to the management and calculation means to produce, by manual action, binary state change information which triggers an instantaneous lateral displacement of the reticle in the same direction as that of the goal, of determined amplitude, immediately followed by the return of the latter to its initial position with a determined constant speed, and to produce then by cessation of the manual action as soon as the reticle coincides again with the goal, the return to the initial state of the binary information and the stopping of the reticle, the calculation means measuring the duration of this manual action and developing, from the duration and distance parameters as well as that of the flight time established as a function of the distance and ballistic parameters, the firing pointing signals in elevation and in bearing.
  • a firing device 1 the barrel 2 of which is oriented by means of orientation in bearing which make the turret 3 rotate about a vertical axis Y, and means of orientation in elevation which tilt the barrel of the barrel by rotation around a horizontal axis X.
  • the orientation of the barrel is represented by the pointing direction DP corresponding to the axis of the barrel.
  • the fire control system comprises an aiming device 4 preferably comprising a video camera 5 delimiting a field of observation and a display monitor 6.
  • the camera is also oriented in the direction of aiming DP.
  • This sighting device also includes a gene symbol erector which can be included in the camera, in order to visualize a reticle of shooting R on the screen of the monitor 6.
  • a telemetry device 8 preferably an optical laser rangefinder, is also oriented according to the pointing direction DP for measure the distance D separating the goal B to be reached from the shooting system.
  • the camera of the aiming device 4 and the rangefinder 8 can be mounted integral with the barrel 2.
  • Various auxiliary sensor devices 9 provide the firing system with signals representing different ballistic parameters (wind direction and speed, air temperature, slope of the tank, barrel arch ).
  • the system is managed by management and calculation means 10, constituting a computer assembly, which groups around a microprocessor 11, random access memories 13, read-only memories 14, and interface circuits 15 and 16. These different elements are all connected to the microprocessor 11 by an address bus 17, a data bus 18, and a control bus not shown.
  • the interface 15 receives the signals from the sensors 9 and is connected to the telemetry device 8.
  • manual control means 20 comprising two switches 20D and 20G are also connected to the computer 10 through the interface 15.
  • the computer is connected via the second interface circuit 16 to the aiming device 4 to transmit reticle positioning signals and, finally, the ES and EG deviation signals for aiming shooting in elevation and in bearing.
  • Fig.3A shows the target B considered located in the field observed by the sighting device 4 and the reticle R which corresponds to the axis of the barrel.
  • the camera 5 delivers to the monitor 6 a composite video signal corresponding to the simultaneous representation of the image of the observed field and of the reticle R.
  • a preliminary phase consists in aligning the barrel on the goal.
  • An operator acts accordingly on commands at his disposal to control the means of orientation in elevation and in bearing and to bring the reticle R which symbolizes the direction of the axis of the barrel to coincide with the goal B and therefore point this direction d DP axis on purpose.
  • FIG. 3B We then obtain the configuration of FIG. 3B.
  • the firing sequence is triggered by the operator, who controls one of the two switches of the device 20.
  • These simple switches are advantageously produced using push buttons whose rest position can correspond to an open circuit and the working position, by operator support, at circuit closure.
  • Binary state change information is thus produced which is transmitted to the computer 10.
  • One of the buttons 20D corresponds to the command to be carried out if the goal moves laterally to the right and the other 20G in the opposite case of a shift to the left. The observation of this displacement is carried out in the considered case of the sighting device on the screen of the monitor 6.
  • We call t o the instant when the operator, having just completed the abovementioned alignment, presses on the appropriate button 20 .
  • the programming of the microprocessor is such that it results from positioning data of the reticle which produces the instantaneous horizontal displacement of the reticle in the same direction as the lateral movement of the goal with a predetermined amplitude E (FIG. 3C).
  • the reticle R is animated with a movement back to its initial position, this movement taking place at constant speed at a predetermined value VR of sign opposite to the lateral speed VB of the goal. This brings about a phase of approximation of the reticle R towards the goal (Fig. 3D).
  • the pressed position of one of the two switches 20D or 20G also triggers via the computer the telemetry device 8 which supplies in return to the microprocessor 11, via the interface 15, the distance D away from the goal.
  • the angle ⁇ 1 of depointing in corresponding deposit can be easily determined by the computer.
  • the difference E of the reticle corresponds to a determined and known angle a E and the speed VR of the reticle being itself known, we obtain ⁇ 1 by the difference between a E and the angular value ⁇ R corresponding to the lateral path VR.Tm of the reticle.
  • ⁇ 1 is linked to the unknown lateral speed of goal B by the relation D being the distance from the goal given by the telemetry.
  • the microprocessor 11 performs the measurement of Tm then the simple calculations giving ⁇ R , then a 1 .
  • the data tg a can be read from a table stored in read-only memories 14 grogrammed.
  • the ROMs 14 contain for each type of ammunition a correspondence table associating with each of the values of a series of distances a flight time corresponding to the ammunition.
  • the flight time is essentially a function of the type of ammunition and the distance D, it is given by the stored tables.
  • the shooting system therefore makes it possible to determine the direction of pointing in a field without having to calculate the lateral speed VB of the goal.
  • the corresponding EG signal results in a LG deviation on the screen (Fig.3F).
  • the system also calculates the rise in the barrel which ensures the flight time TV at the distance D presented, that is to say the signal ES to which the difference LS corresponds on the screen.
  • the position of the canon axis on the screen corresponds to that of the initial reticle R and is then symbolized by a crosshair in broken lines in Figs.3D to 3G.
  • the diagram Fig. 4 recalls as a function of time the various actions of the operator, the events they cause, and the correspondence with the diagrams 3A to 3G.
  • the computer 10 is not described in detail, but a preferred implementation of the fire control system according to the invention provides that the microprocessor 11 is not used to calculate the ballistic parameters of the fire. It searches in tables, frozen in all of the programmed read-only memories 14, for the different values meeting the firing conditions according to the munition chosen.
  • the microprocessor however performs the calculations which have been described previously and various additional calculations such as appr linear ximations.
  • the interface 15 includes analog-digital converters to supply the microprocessor with the various data in digital form.
  • the interface 16 includes digital-analog converters followed by amplifiers 25 and 26 in order to deliver the reticle signals.
  • the program of the calculation means 10 provides for the cancellation of the measurement by closing consecutive to an opening of one of the two push switches 20D, 20G, the measurement of the time Tm being validated only after '' a certain time, for example after approximately 0.5 seconds.
  • the calculator 10 determines the angle of increase in shooting ⁇ , it calculates the correction to be made to the angle a 2 of aiming compensating only the lateral speed VB of the goal.
  • the microprocessor It can be programmed differently. It can command the triggering of the measurement of the distance D by means of the rangefinder 8 as soon as the goal is taken over. In this case, this can allow the computer 10 to adjust the speed of movement VR of the reticle R as a function of the distance D measured by the laser rangefinder 8.
  • the means used to develop the reticle R being preferably incorporated into the camera 5, this makes it possible to use several display monitors 6 on board the same combat tank, one for the shooter and one for the tank commander for example .
  • the firing system according to the invention without departing from the scope thereof. It is for example conceivable to replace the camera 5 used in the sighting device 4 by a optical sighting system, the image of the reticle R being collimated and superimposed on the image of the field of observation.
  • the camera 5 can also be simply replaced by a device with a photodetector array, for example with a charge transfer circuit, in front of which a field scan is produced; such a device can correspond to a FLIR (from the English terminology "Forward Looking Infra Red").
