Description
Technical Field
The invention belongs to the technical field of war-leading devices, relates to a mechanical transmission war-leading device, and particularly relates to a war-leading device which utilizes wind resistance to transmit power to realize mechanical transmission.
Background
The high-energy fuel is filled in the bulk detonation warhead, and is thrown into the air under the explosive detonation throwing driving action, the high-energy fuel is mixed with the air to form a large-range active cloud cluster, and the active cloud cluster is secondarily detonated by the detonating device to generate bulk detonation and release strong shock waves, so that the high-energy fuel bulk detonation warhead is one of the most powerful weapons.
The whole-course movement speed of the body detonation warhead is within 50m/s, two initiation devices can be used and are symmetrically distributed, and the symmetry of a warhead system is improved. The active cloud cluster formed after the body detonation warhead is thrown is flat and cylindrical, and a cavity is arranged in the center of the cloud cluster. Wang Yongxu et al report in "300kg charge FAE fuel explosion misting experimental study" (blasting apparatus, 4 months 2020, vol 49, page 2, 27): the detonation position of the detonation device is crucial, and the detonation device cannot be too close to the center of the cloud cluster because of the cavity in the center of the cloud cluster, and the area has little fuel or low fuel concentration; meanwhile, detonation products of the thrown explosives and shell fragments can damage the initiation device, so that the initiation device cannot be detonated normally. The initiation device also cannot be too far from the cloud centre, otherwise the initiation device cannot completely initiate the entire cloud. The document gives an empirical formula for the optimal initiation position.
Yao Jinxia et al reported a method of throwing a priming device in the document "current state of development and prospect of fuel-air explosives" (flying missile, 2 nd 2014, page 2). The priming device is fixed on the side wall of a shell of a body detonation warhead part, and is thrown to obtain a certain radial velocity while fuel is thrown to form a cloud cluster by using the explosion of a central explosive, and the priming device is provided with a delay fuse and is detonated after reaching a delay time. The velocity deviation of this throw mode initiation device is large.
Shi Changjun et al report in "anti-interference method for secondary detonation fuse in cloud blasting warhead" (teaching for warrior and guidance, 2016, 8/2016, vol 36, page 4, 51): the delay Shi Yinxin on the priming device is hundreds of milliseconds in delay time with 1% precision. In summary, the speed and the detonation time of the detonation device both deviate, the positional deviation of the detonation device during detonation is large, if the detonation device deviates from the optimal detonation position, the force of the warhead is reduced, and if the detonation device deviates from a cloud cluster, the cloud cluster cannot detonate, and the warhead fails.
