Electromechanical contact fuse for warhead of aerial rotary rocket projectile

Abstract

The invention discloses an electromechanical contact fuse of a warhead of an aerial rotary rocket projectile. The electromechanical contact fuse comprises a body, a collision trigger switch, an inertia trigger mechanism, an explosion-proof mechanism, a centrifugal safety mechanism, a fuse piece safety mechanism, a fault prevention mechanism, a thermal battery activation mechanism, a recoil safetymechanism, a detonating tube, a booster tube, an upper body, a circuit box, a thermal battery assembly, an electric ignition tube assembly, a pressing ring, a shooting body, a standby fastening screwand at least one short-circuit switch. The circuit box is supplied with power by the thermal battery assembly; the thermal battery assembly is activated by the thermal battery activation mechanism; and the short circuit switch enables the electric ignition tube assembly to be in a short circuit state at ordinary times so as to prevent accidental ignition. The fuse has a fault prevention function,ensures that the fuse is in a safety state in an active stage of the projectile so as to ensure the safety of an aerial carrier; the fuse adopts two ignition modes, including collision triggering andinertia triggering, has a small-falling-angle triggering function and achieves high action reliability; the fuse also has a fire insulation function and can guarantee the treatment safety of unexploded explosives; and the fuse is simple in structure and low in cost.

Description

technical field [0001] The invention belongs to rocket fuze technology, in particular to an electromechanical trigger fuze for aviation rotary rocket warhead. Background technique [0002] Traditional standard aviation rockets mostly use proximity fuzes, including capacitive proximity fuzes, laser proximity fuzes, and radio proximity fuzes, etc., or multi-functional fuzes with proximity functions. Fuzes have complex structures and high costs. Proximity fuzes are prone to ballistic bombing problems, which pose a safety hazard to the carrier aircraft. Moreover, standard fuzes seldom have the function of wiping the ground. When the aircraft flies near the ground and launches ammunition, the ammunition tends to land in a small corner, with a low effect rate and a high dud rate. Contents of the invention [0003] The purpose of the present invention is to provide an electromechanical trigger fuze for the warhead of an aviation rotary rocket, which has the function of wiping th...

Proximity fuzes are prone to ballistic bombing problems, which pose a safety hazard to the carrier aircraft

And the standard fuze seldom has the function of wiping the ground. When the aircraft flies near the ground and launches the ammunition, the ammunition often lands in a small corner, the effect rate is low, and the dud rate is high.
