Definitions

  • the present invention relates to a fire control system for a straight-fire weapon, in particular a cannon, mounted on a rotary wing aircraft, such as a helicopter.
  • the subject of the present invention is a fire control system for a tight-shot weapon mounted on a rotary wing aircraft capable of being actuated by the pilot himself and allowing total decoupling between the aiming carried out by the pilot and the corrections shooting.
  • the firing control system for a tensioned weapon mounted on a rotary wing aircraft capable of being actuated by the pilot himself and comprising an electronic calculator, said weapon being mounted rotatable around two transverse axes thanks to motor means controlled by said calculator, is remarkable in that it comprises a sighting system on which are likely to appear simultaneously a target and a marker, said marker being able to be moved on said system of aiming by a pilot command, as well as means for determining the coordinates of the position of said reference point with respect to an axis system linked to the aircraft and transmitting them to said electronic calculator at least when, on said aiming system , said mark is brought into superposition on said target.
  • the sighting system is of the semi-transparent mirror type allowing the target to appear by transparency and forming the image of a light symbol generated by an electro-optical device, for example a cathode ray screen, said image constituting the reference, while the electro-optical device forms said means for determining the coordinates of the reference point and transmitting them to the electronic calculator.
  • an electro-optical device for example a cathode ray screen
  • the pilot after having detected a target can orient the axis of his aircraft towards it, thanks to the flight controls, until the alignment is roughly achieved and the target appears in the field of the mirror. of sight. Then, by continuing to pilot to maintain and if possible perfect this alignment, by means of a control member, it makes the reference mark coincide with the target on the aiming system.
  • Means for indicating to the calculator the distance separating the aircraft from the target are provided in said system. These means are constituted by a display device controlled by the pilot or by a telemetry device.
  • the calculator receives the coordinates of the sighting frame, that is to say those of the target when the coincidence is obtained by the pilot. It also receives information concerning the distance separating the aircraft from the target. In addition, the calculator receives gyrometers, gyroscopes and / or on-board anemometric sensors, information concerning the attitude and the attitude variations of the aircraft, as well as its relative speed with respect to the ambient air. All of this data is used to predict the movement of the target and determine the orientation to give to the weapon.
  • the calculator is programmed to take into account the movement of the target. If accelerations are involved, it is necessary to measure the distance between the target and the aircraft, not just to estimate it.
  • the calculator program assumes that the target follows a rectilinear trajectory at constant speed (or at constant acceleration) during the flight time of the projectile fired by the weapon and it makes it possible to determine the position to be given to the weapon relative to a reference linked to the aircraft so that the trajectories of the target and of the projectile cut at the same time.
  • the system according to the invention is intended to conduct the firing of a cannon 1 mounted on a helicopter (not shown) with a longitudinal axis L-L '.
  • the barrel 1 for example integral with a turret (not shown), can rotate around a bearing axis ZZ 'and a site axis YY' under the action of motors or jacks 2 and 3, respectively .
  • This system comprises a clear sight 4, of the semi-transparent mirror type, through which the pilot whose only eye 5 is represented in FIG. 1, can see a target 6, for example an enemy helicopter.
  • the center of the viewfinder 4 passes for example by the axis LL 'of the helicopter provided with the system according to the invention or occupies a fixed position determined relative to it and the plane of said viewfinder is inclined at 45 ° relative to said axis L-L '.
  • an electro-optical device 7, on which a symbol 8 appears Under the viewfinder 4 is provided an electro-optical device 7, on which a symbol 8 appears, the arrangement being such that the pilot can see simultaneously on the viewfinder 4 the target 6 and the image 8 'of the symbol 8.
  • the position the symbol 8 on the screen 7 (and therefore that of the image 8 'on the viewfinder 4) can be adjusted according to two perpendicular axes YY' and ZZ 'one of which is for example in the vertical plane passing through the axis L-L ', by action on a control button 9, available to the pilot and for example mounted on the handle 10 of cyclic control.
  • Two reference axes for example engraved on the viewfinder 4 and carrying respectively the marks y 1 -y ' 1 and zl-z'1, allow the pilot to align with the axis LL' when it makes the optical coincide l 'image of the axes yy' and zz 'on the viewfinder 4 with said reference axes.
  • a control button 11 for displaying the value at which said pilot estimates the distance separating him from the target 6, when the system does not include any rangefinder performing this measurement automatically.
  • the system according to the invention finally comprises a microcomputer 13 in connection with the electro-optical device 7, the distance display device 12, the on-board gyrometers 14, the on-board gyroscopes 15 and an anemometric sensor 16, of which it receives information, as well as with engines 2 and 3, to which it sends orders.
  • the fire control system makes it possible, on the one hand, to facilitate the aiming of the target 6 by the pilot, and on the other hand to decouple the shooting corrections from the aiming.
  • the pilot When it has detected a target 6, the pilot orients the axis L-L 'of its aircraft, using its flight controls, until the target 6 is in the field of its clear sight 4.
  • this direction of sight coincides with the longitudinal axis of the helicopter.
  • the pilot by means of the control button 9 placed on its cyclic stick 10 will make coincide the image 8 'of the symbol 8 and the target 6.
  • the work of the pilot is then to pursue the target 6 with the symbol 8 during all the phase of aiming of the weapon and the shooting, so as to constantly maintain the coordinates C b " E b of the target respectively equal to the coordinates C a , E of image 8 '(see Figure 2).
  • the control button 9 is a button with "two axes" (site and deposit) making it possible to move the image of the symbol on the viewfinder. If the pilot exerts a force on the control button 9, the symbol 8 moves in the direction corresponding. In the absence of action on the button 9, the image of the symbol 8 keeps a fixed position on the clear viewfinder 4 and therefore indicates a fixed direction in a frame linked to the helicopter.
  • the pilot has two means for refining and continuing the aiming, namely his flight controls and the control button 9. He uses this last button, in particular in the case where the aiming at the flight controls would bring him towards areas of dangerous theft.
  • the calculator processes this information and deduces the score to be given to the barrel 1 so that the shell reaches the target 6.
  • a simple assumption taken into account in the calculator 13 program to calculate the score for weapon 1 is that the target 6 moves in a straight line and at uniform speed during the time of the shell journey. If the helicopter is equipped with a rangefinder, a hypothesis on the acceleration of the target can be taken into account.
  • the instructions from the calculator 13 give the site sc and the gc deposit to be given to the gun and are sent to the rotation servos 2 and 3 of the latter.
