The purpose of this utility model is, on the basis of former technology, additional several means, realize the emission common cartridge, can obtain and the almost corresponding to effect of ballistic trajectory, flying speed, flight time that strengthens each point in rocket projectile post-boost phase starting point to the 1.7 times battle-sight range, and the correction that can facing the wind inclined to one side training.
Above-mentioned purpose of the present utility model is that (one) that realizes in the following manner increases a time-delay firing device in the firing pin chamber below rocket launcher, and its operation principle is similar to the operation principle of common cannon recoil brak, and its inside is full of liquid.The time-delay firing device plays a part to postpone emission, so that the flight time and the live shell basically identical of simulating training shell each point in live shell post-boost phase starting point to 1.7 times battle-sight range.(2) increase a pressure regulator at the gun barrel rear portion, kick when offsetting the emission of common firearms, and make muzzle velocity drop to the initial velocity of design, make the flying speed of bullet each point in live shell post-boost phase starting point to 1.7 times battle-sight range consistent with live shell.(3) increase a gun sight Connection Block.Textural, the gun sight Connection Block is a specific angle because the slotting falcon of its pedestal slot and sliding seat is staggered on meridian plane, so connected gun sight, its aiming zero line and body of a gun axis also just form a specific angle, this special angle can make the ballistic trajectory of simulating training shell each point in live shell post-boost phase starting point to 1.7 times battle-sight range almost consistent with the ballistic trajectory of live shell under the comprehensive function of the flying speed that provides with pressure regulator.The gun sight Connection Block also can be used for the correction training of facining the wind inclined to one side.
Major advantage of the present utility model is: (one) compared with the prior art, simulating training shell more approaches the outer trajectory characteristic of live shell in ballistic trajectory, flying speed and the flight time of the interior each point of the straight distance of post-boost phase starting point to 1.7 times.(2) shooter can shoot by rear sight, the moving target lead of Extended Range Rocket bullet and the inclined to one side correction of facining the wind.Unmatched towards the back seat phenomenon during emission, the sound during except emission and dynamic sense are less than the live shell, and be all identical with the live shell training effect.(3) this simulating training shell adopts the common cartridge of standard, compares with the bullet that adopts extraordinary explosive payload, and cost is low, is easier to management.
