A Flyer Type Heat Sensitive Burst

Abstract

The invention discloses a flying plate thermosensitive squib which includes a pedestal, a packaging base and a detonation propagation sequence which is installed on the pedestal and is packaged by thepackaging base. A first columnar accommodating chamber and a second columnar accommodating chamber are arranged on the pedestal and are connected to each other. A square pedestal groove and a squarepedestal boss are arranged at one side of the second columnar accommodating chamber. The square groove is located at the inner side of the square boss. The detonation propagation sequence comprises first charge and second charge, wherein a flying plate is located beside the first charge. A gun barrel is disposed at the outer side of the flying plate. A charging ring is arranged on the outer side of the gun barrel. The packaging base includes a square packaging boss and a square packaging groove. A third columnar accommodating chamber is arranged on the packaging base in the opening direction of the second columnar accommodating chamber, wherein a thin sheet is arranged on the inner side of the third columnar accommodating chamber. The flying plate thermosensitive squib guarantees action spontaneity in special status, such as fire hazard, and solves a problem of difficult of conversion from combustion to detonation of an insensitive explosive, and can enhance detonation development constrain.

Description

technical field [0001] The invention relates to a detonator, specifically designs a flyer-type heat-sensitive detonator that relies on ambient heat and belongs to the technical field of explosives. Background technique [0002] The cutting cable forms a metal jet under the action of the input detonation wave, which can cut various materials and is widely used in military and civilian fields. Generally, the cutting wire charge is detonated by the detonator at the front end. However, the explosives used in conventional detonators are relatively sensitive and cannot adapt to high and long-term environmental temperature shocks; shock-disc detonators are limited in their scope of use due to harsh detonation conditions. [0003] For example, when the missile is flying and launching, due to the high-speed friction between the shell and the air, heat will accumulate, and the temperature will be high (over 150°C when flying, and above 300°C when launching, or even higher) and the du...

AI Technical Summary

Problems solved by technology

[0004] The patent of the present invention discloses a non-electric detonator with high temperature resistance and safety, in order to solve the safety accidents caused by the rapid rise of the ambient temperature, the pressure in the airtight cabin rises until it explodes, and the safety door cannot be opened normally.

[0005] The detonation transfer sequence disclosed in the patent of the present invention pushes the flyer to detonate the explosive through the combustion of the explosive, in order to solve the problem of difficulty in transitioning from the combustion of the temperature-resistant explosive to detonation and low reliability.
