Background
Under the working mode of secondary detonation of the cloud detonation of the powerful rocket, the bullet is separated from the parent bomb at a certain height and is decelerated to delay the falling time, and the bullet is dragged into the formed cloud cluster and detonated through a high-tensile-strength towing cable which is rapidly released between the bullet and the parent bomb, so that the warhead exerts the maximum power. After one end of the high-strength streamer is subjected to self-locking fixation by adopting a special coiling method, one part of the high-strength streamer is wound on a spool of a pay-off device according to the process requirement of parallel close winding, and the other part of the high-strength streamer is wound on a roller of a parent bomb damping device. In the process of separating the bullet from the mother bullet, the high-strength towing cable is gradually released from the bullet end pay-off device and the mother bullet end damping device, and after the towing cable is released, the bullet and the mother bullet move at the same speed at a certain distance through the pulling action force of the towing cable, so that accurate secondary detonation is realized when the bullet falls into the center of the cloud cluster.

Therefore, reliable fixing, precise winding and reliable releasing of the towing cable are realized in a limited space, a similar winch steel wire clamping plate clamping and fixing mode and a spiral winding and releasing method are not suitable, a fixing and releasing device without damage to the towing cable is adopted, and the design requirement of accurate secondary detonation of the high-power cloud detonation bomb is met.
In a domestic researched rocket cloud bomb weapon system, a secondary detonation working mode does not exist. Thus, there is no problem with reliable fixing and releasing of the streamer. The invention patent with application number 20111001017.6 describes an onboard optical fiber towing bait casting deceleration device, which comprises a rubber air bag, a metal friction plate and a stamping air guide pipe. The rubber air bag is automatically inflated by punching the air entraining pipe, so that the rubber air bag has proper pressure under different flight conditions of the airplane, and accordingly, proper friction force is generated between the reel and the metal friction plate, and the speed reduction function in the throwing process is realized. Because the towing line diameter is smaller, the installation space is large, the cruising speed of the aircraft and the bait release speed are relatively lower, the release environment is better than the missile-borne environment, strong impact response borne by the towing cable after the bullet is instantly thrown under the working mode of secondary detonation of the powerful cloud detonation bomb is avoided, the bait is released through the throwing speed reducer, the force bearing of the towing line is relatively lower, and similar fixing and releasing problems do not exist.
