The invention relates to a recoil generating device for a small arm simulator. The simulators of small arms such as 0.762 SLR rifle, 9mm carbine, 9mm pistol, light machine guns and similar weapons may use the recoil generating device. The device generate recoil by utilizing compressed gas such as air, C02 and any other non-toxic gas. The recoil generating device according to the invention can be utilized in simulators of small arms either to impart training to persons or to study the characteristics of small arms or measurement of static and dynamic parameters of different weapons. Accordingly the invention provides a recoil generating device for a small arm simulator comprising a dummy weapon having an extended barrel with a coUimated light source, grip, breech block with a piston attached to it, a magazine, a trigger and a butt, characterized in that said recoil generating device comprising a recoil generating piston in a cylinder with a compressed gas connector, said recoil generating piston being located for hitting on the piston attached to the breech block of the dummy weapon when compressed gas is provided through the compressed gas connector, a trigger sensor comprising a photo emitter, a photo receiver and a sensing lever located to move between said photo emitter and said photo receiver while triggering, to produce an activating trigger signal to allow compressed air through said compressed gas connector. The figure 1 of the accompanying drawing shows a typical recoil generating system attached to a dummy AK-47 assault rifle. In figure 1 the small arm simulator according to the invention comprises a dummy weapon having an extended barrel (4) with a coUimated light source (1, 3), a grip (19), a piston (8) fixed to a breech block (9), a magazine (12), a trigger (18) and butt (20). Operating the trigger (18) will send a collimated light from the extended barrel (4). The recoil generating device according to the invention comprises a recoil generating piston (7) in a cylinder with a compressed gas connector (5). Compressed gas is allowed to the gas connector through a solenoid valve. When the solenoid valve opens, the recoil generating piston (7) is pushed and hit the piston (8) fixed to the breech block (9) to provide the required recoil. The pressure at which the recoil generating piston (7) hits the piston (8) fixed to the breech block (9) is adjusted depending upon the type of weapon on which training is given or testing is carried out. A trigger sensor comprises a photo emitter (13) and photo receiver (14) located on the opposite sides of a sensing lever (15) located between them. The sensing lever (15) intercept the light emitting from the photo emitter (13), which in turn produces an activation signal at the output of the photo receiver (14). This activation signal is used for activating the solenoid valve through which compressed gas is allowed to flow through the compressor connector to push the recoil generating piston (7). The recoil generating piston (7) hit against the piston (8) fixed to the breech block (9) of the dummy weapon. The compressed gas pressure is adjusted for the required recoil depending upon the type weapon on which the trainee is being trained or measurement is being taken. Since piston is attached to the breech block (9) the recoil is felt on the breach block (9). A hammer hit sensor (10) is provided in the barrel to sense the movement of a sensing pin (SP) located in the path of a firing pin (11). The firing pin (11) is hit by hammer when the trigger (18) is pressed. The hammer hit sensor (10) senses the firing and produces a signal indicating the firing of the weapon. The magazine (12) is provided with a catch (17) to hold the magazine and sensors are provided to indicate that magazine is attached to the weapon. The number rounds available on the magazine can be adjusted depending upon the type of weapon on which the training is being provided. The system can be adapted for training on various type of small arms. By fixing an appropriate travel time for the recoil generating piston in the recoil generating device a realistic recoil can be achieved on various types of small arms. WE CLAIM : 1. A recoil generating device for a small arm simulator comprising a dummy weapon having an extended barrel with a collimated light source, grip (19), breech block (9) with a piston (8) attached to it, a magazine (12), a trigger (18) and a butt (20), characterized in that said recoil generating device comprising a recoil generating piston (7) in a cylinder with a compressed gas connector (5), said recoil generating piston (7) being located for hitting on the piston (8) attached to the breech block (9) of the dummy weapon when compressed gas is provided through said compressed gas connector (5), a trigger sensor comprising a photo emitter (13), a photo receiver (14) and a sensing lever (15) located to move between said photo emitter (13) and said photo receiver (14) while triggering, to produce an activating trigger signal to allow compressed air through said compressed gas connector. 2.
