System for simulating the firing of a weapon at a target

Abstract

Abstract THE INVENTION CONCERNS A SYSTEM FOR SIMULATING THE FIRING OF A WEAPON, IN PARTICULAR A WEAPON MOUNTED ON A MOVABLE WEAPON CARRIER, AT A TARGET, PARTICULARLY A MOVING TARGET THE SIMULATOR SYSTEM INCLUDES A RADIATION TRANSMITTER FOR EMITTING A NARROW BEAM OF OPTICAL RADIATION, WHICH IS MOUNTED ON OR COUPLED TO THE WEAPON SO AS TO FOLLOW THE AIMING MOVEMENTS OF THE WEAPON IN AZIMUTH AND ELEVATION. THE TRANSMITTER COMPRISES A MIRROR OR SOME SIMILAR OPTICAL MEMBER DETERMINING THE EMISSION DIRECTION OF THE TRANSMITTER AND THIS MIRROR IS ROTATABLE SO THAT THE EMISSION DIRECT CAN BE MOVED IN AZIMUTH AS WELL AS IN ELEVATION BY CORRESPONDING ROTATION OF THE MIRROR. BEFORE THE INSTANT WHEN THE FIRING OF A PROJECTILE WITH THE WEAPON AT THE TARGET IS SIMULATED, THE MIRROR IS LOCKED IN A PREDETERMINED POSITION SUCH THAT THE EMISSION DIRECTION OF THE TRANSMITTER IS PARALLEL TO THE DIRECTION OF FIRE OF THE WEAPON. AT THE INSTANT OF A SIMULATED FIRING OF A PROJECTILE THIS LOCKING IS RELEASED AND THE MIRROR BECOMES GYROSTABILIZED SO AS TO BE INDEPENDENT OF ANY SUBSEQUENT MOVEMENTS OF THE WEAPON. IN ITS GYRO-STABILIZED UNLOCKED STATE THE MIRROR IS ALSO COUPLED TO A SERVOMOTOR FOR ROTATION OF THE MEMBER IN A DIRECTION CAUSING A CHANGE OF THE EMISSION DIRECTION OF THE TRANSMITTER IN ELEVATION. A COMPUTER UNIT IN THE SYSTEM COMPUTES THE PROPER GRAVITY CORRECTION ANGLE OR SUPERELEVATION ANGLE OF THE WEAPON FOR THE FIRING OF A REAL PROJECTILE AT THE TARGET AND PRODUCES A SIGNAL PROPORTIONAL TO THIS COMPUTED GRAVITY CORRECTION ANGLE. THIS SIGNAL IS SUPPLIED TO SAID SERVOMOTOR SO THAT THE GYROSTABILIZED EMISSION DIRECTION OF THE RADIATION TRAMSMITTER IS LOWERED IN ELEVATION THROUGH AN ANGLE EQUAL TO THE COMPUTED GRAVITY CORRECTION ANGLE. THE COMPUTER UNIT COMPUTES ALSO THE TIME OF FLIGHT TO THE TARGET FOR A REAL PROJECTILE AND AFTER A TIME INTERVAL EQUAL TO SAID COMPUTED TIME OF FLIGT AFTER THE INSTANT OF THE SIMULATED FIRING OF A PROJECTILE THE COMPUTER UNIT ACTIVATES THE RADIATION TRANSMITTER TO EMIT A SHORT PULSE OF RADIATION. ON THE TARGET RADIATION SENSITIVE RECIEVING MEANS ARE PROVIDED FOR DETECING ANY RADIATION PULSES RECEIVED AT THE TARGET FROM THE RADIATION TRANSMITTER ON THE WEAPON.
