Definitions
- the technical sector of the present invention is that of the pointing systems of a weapon ensuring its stabilization.
- a first method consists in measuring the disturbing angular velocity, for example by means of a gyrometric type, and using it to control the speed of rotation of the motorization system placed between the support and the weapon. It is therefore an anticipation control placed in parallel with a servo control of the position of the weapon on an inertial reference whose efficiency is low to attenuate the amplitude of the angular disturbances for frequencies, averages.
- an anticipation control placed in parallel with a servo control of the position of the weapon on an inertial reference whose efficiency is low to attenuate the amplitude of the angular disturbances for frequencies, averages.
- Another method is to provide a motor for controlling the torque applied to the load. This principle is used to improve the efficiency of reducing the effects of angular rate disturbances. This method is suitable for low decentering values. For example, reference can be made to US-4387624.
- the object of the present invention is to provide a pointing system of a weapon mounted on a mobile carrier allowing a motorization with pre-stabilization to separate the sizing requirements of the motorization caused by the decentering of the weapon, the one that allows to privilege the quality of the control of orientation.
- the subject of the invention is therefore a pointing system in the site of a weapon, characterized in that it comprises a first means for positioning the weapon in a large deflection in relation to a first axis of rotation offset by relative to the center of gravity of the weapon and a second means of positioning the weapon connected to the first means following a low deflection in location with respect to a second axis of rotation passing through the center of gravity of the weapon.
- the first axis of rotation is located behind the center of gravity of the weapon.
- the first positioning means is articulated with respect to a frame on which the weapon is mounted around the first axis of rotation.
- the first positioning means comprises a flange supporting the weapon and connected to the frame and a rotation means, the first axis of rotation being disposed between said flange and the frame.
- the rotation means ensures the rotation of the flange relative to the frame.
- the weapon is mounted rotatable relative to the flange, the second positioning means ensuring the rotation of the weapon relative to the flange around the second axis.
- the rotation means is constituted by a jack.
- the second positioning means comprises a motor or geared motor integral with the flange along the second axis of rotation.
- the second positioning means comprises a cylinder integral with the flange and whose rod is connected to the weapon.
- the second positioning means comprises a cylinder integral with the flange and whose rod is connected to the frame.
- the second positioning means comprises a deformable parallelogram connecting the flange to the frame and an actuator integral with a branch of the parallelogram engaged with the second axis of rotation.
- a first advantage of the system according to the invention lies in the respect of the organization requirements of the weapon system by moving the axis of articulation to meet the constraints of functional optimization or overall optimization.
- Another advantage lies in the respect of the need for quality of absolute orientation to be imposed on the weapon by the adoption of a second articulation at the center of gravity.
- Another advantage lies in the reduction of parasitic couples between the weapon and the flange.
- the invention consists in providing two engines of the weapon relative to its support.
- a first engine, or main engine allows to steer the weapon in a coarse manner.
- This motorization allows to position the weapon without any constraint.
- a second motorization allows to orient the weapon finely by leaning on the main engine.
- the advantage of such a system lies in the fact that the clearance between the weapon and the flange is limited to stabilization errors, which leads to a very simple realization.
- the dimensioning of the second motorization being linked only to the inertia of the weapon to steer, a powerful torque control is performed without specific constraints.
- FIG. 1 shows the weapon 1 to be orientated in a site secured to a flange 2 itself rotatably mounted relative to a support 5, for example a turret, by means of journals 6 and bearings 7
- the flange 2 is in the form of a cage in which the rear part of the weapon is engaged.
- the weapon 1 is itself mounted to move relative to the flange 2 by means of journals 8 connected to an actuator 4 by means of a shaft 9 and by bearings 10.
- the pins 6 and the bearings 7 define the axis A1 around which is the main motorization following a large deflection and the rotation of the flange 2, so the weapon relative to the support 5.
- the pins 8 and the bearings 10 define the axis A2 around which is done the secondary motorization following a low clearance and the rotation of the weapon relative to the flange.
- the actuator 4 is a motor integral with the flange.
- FIG. 2 shows the weapon 1 mounted on a support 5 via a frame 11.
- the rotation of the flange 2 is obtained using the rotating means 3 consisting of a jack whose rod 12 is secured to the flange 2 via an axis 13 and the body of the frame 11.
- the flange 2 is rotated, so the weapon 1 around the pins 6 to roughly orient a large amplitude the weapon relative to the frame 11.
- This amplitude can cover a range of the order of -10 to + 60 ° following the arrow F1.
- the weapon 1 is itself rotatably mounted relative to the flange 2 at a low amplitude to ensure its fine orientation.
- This rotation has been schematized by the arrow F2. This rotation takes place here with the aid of a jack 14 whose body is secured to the flange 2 and the rod of the weapon. This jack 14 prints a movement of the weapon around the pins 8 relative to its supporting structure that is to say the flange. This amplitude can cover a range of about 1 °.
- FIG 3 there is shown a view of a weapon 1 provided with the flange 2 surrounding the entire rear part of the weapon.
- This flange comprises an interface 15 connecting to the frame 11, a passage opening 16 for receiving the bearings 10 (not shown) receiving the journals 8.
- the flange is provided with a bellows 17 to close the door. space between the tube of the weapon and this flange.
- system according to the invention is integrated in a complex assembly for orienting the weapon according to firing coordinates, to determine its position and its deviations from a setpoint, to measure the pointing variations during rolling and correct any deviations measured.
- the tightness to put in place at the bellows 17 therefore has a relatively small dimension and the limited movement does not require the introduction of a friction system but simply a system with elastic bellows.
- the bearings of this joint are also limited in size in that they do not have to integrate heavy functional constraints (feeding of the weapon for example).
- the acceleration disturbances have no effect on the orientation of the weapon.
- an actuator 4 to ensure the small amplitude of the movement of the weapon relative to the flange 2.
- This actuator can be in fact an electric gear motor whose servocontrol in bandwidth effort is sufficient and of sufficiently low stiffness. It is also possible to envisage a hydraulic motorization constituted by a hydraulic cylinder with low clearance. To impose a minimum of elasticity on the oil, one can artificially increase the dead volume of each of the two chambers of the cylinder by small accumulators purged.
- the actuator with pressure control is used to enslave the absolute speed of the weapon, speed obtained directly by a gyro or from a gyroscope mounted on the flange 2, with derivation of the sum the gyro gap and the relative position between the flange 2 and the weapon 1.
- FIG 4 there is shown a secondary drive constituted by a jack 18 whose body is secured to the frame 11 with the aid of an axis 19 and whose rod is secured to the weapon.
- This articulated jack absorbs the relative movements between the weapon and the frame and ensures the fine motorization of the weapon.
- FIG. 5 shows a secondary motorization consisting of a deformable parallelogram 20 whose arm 21 connects the trunnions 7 and 8 and the arm 22 the trunnion 7 and the frame 5.
- This parallelogram is completed by a fourth point 24 to which the arms 23 and 25 are connected.
- a geared motor 26 integral with the journal 8 makes it possible to actuate the weapon in rotation with respect to the flange 2 by resting on the frame via the arm 25.
- any secondary motorization capable of applying on the cradle of the weapon a torque in a sufficient bandwidth may be used.
