Embodiment Construction

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] The purpose of the present invention is to provide an active and passive multi-stage buffer energy-absorbing structure oriented to the survival requirements of the internal components of the missile body, which can buffer and absorb energy at the moment when the positioning missile strikes the target, so as to ensure the survival rate of the core components of the positioning missile, and to return the attack to the target. info...

Abstract

The invention discloses an active and passive multi-stage buffering energy-absorbing structure facing the survival requirement of an internal component of a projectile body. The active and passive multi-stage buffering energy-absorbing structure comprises a tray, a first passive energy-absorbing structure, a second passive energy-absorbing structure and an active energy-absorbing structure. The first passive energy absorption structure comprises a pull rod and an expansion pipe arranged on the outer side of the pull rod in a sleeving mode. The second passive energy absorption structure comprises a first energy absorption ring connected with the tray in a welded mode and a second energy absorption ring detachably installed on the second-stage missile. The active energy absorption structure comprises a cylinder body, a piston, a rod body and a magnetic coil. Compared with the prior art, the active and passive multi-stage buffering energy absorption structure conducts buffering energy absorption at the moment when the positioning missile hits the target, the survival rate of the core assembly of the positioning missile can be guaranteed, and relevant information of the hit target is transmitted back.

Description

technical field [0001] The invention relates to the technical field of buffer energy absorption, in particular to an active and passive multi-stage buffer energy absorption structure that meets the survival requirements of internal components of a projectile. Background technique [0002] As the form of warfare continues to develop in the direction of digitization, unmanned, remote and intelligent, strike accuracy is undoubtedly an important indicator of future warfare. In the process of missile strike, due to the influence of climate environment, calibration error and other factors, there is often a certain deviation between the actual landing point and the expected landing point. In addition, if the enemy interferes with our satellite's target positioning, navigation and guidance and other functions, it will inevitably lead to a further decline in the accuracy of missile strikes. In such a strong interference environment, if a positioning missile that can return informati...
