Description
Technical Field
The invention relates to a detonator detonating device, in particular to a multipoint sequential detonating in-line type parent bullet detonator.
Background
The primary and secondary bullets are a weapon in which a certain number of same or different types of bullet warheads are arranged in one primary bullet, the primary bullet is opened at a preset throwing point, and the bullets are thrown out of the primary bullet according to preset time intervals, so that a certain scattering area and a certain scattering density are formed. The primary and secondary bullet relates to a plurality of key technologies, and the primary bullet fuze technology for controlling the primary bullet initiating explosive device to open the cabin and the initiating explosive device to throw out is one of the key technologies. After the parent bullet reaches a preset position, the parent bullet fuze firstly detonates the cutting rope to complete the cabin opening function, and then detonates the explosion bolts according to a preset time interval to complete the throwing of a plurality of bullets, so that the bullets are ensured to be in a supposed spreading state above a target area, and a better damage effect is achieved.
At present, the domestic multi-point detonation system generally adopts conventional initiating explosive devices such as an explosion logic network and the like as initiating elements, and because a large number of conventional initiating explosive devices are used, the initiating explosive devices are required to have independent mechanical safety devices, and the independent safety devices have mechanical movement because of adopting a dislocation type mechanical explosion-proof fuse device, and cannot be checked before the warhead is assembled, so that the safety and the reliability of the warhead are reduced, and the weight and the volume of the warhead are increased.
In-line fuses established by striking sheet detonators with core components in weapon fuze systems have attracted general attention from the domestic and foreign fuze world since the first disclosure in the united states in the 70 s of the 20 th century. The multipoint sequential detonating fuze based on the in-line fuze can avoid a plurality of sets of mutually independent mechanical safety devices, and has the advantages of small volume, high time precision, large adjustable range of detonating interval time and high safety and reliability.
After the electronic component of the single-point detonating and the multi-point simultaneous detonating in-line type fuze detonates the detonators, all functions are completed, the influence of the detonators on the electronic component is not required to be considered, and the structural design is relatively simple. The in-line type mother bullet fuze for multi-point sequential detonation has the advantages that as the condition of reliable detonation of the N-1 detonator is that after the detonation of the N-1 detonator, the electronic component is not damaged by detonation energy of the N-1 detonator, the integrity and the functionality of the fuze are not affected, and meanwhile, the detonation product of the N-1 detonator is sealed in a smaller space and does not affect other components of the whole bullet, the structural constraint factors are more, and the design is relatively difficult and complex.
