Separable ignition device

Abstract

The invention discloses a separable ignition device which comprises ignition composition (6) and also comprises an fire transferring tube (2), an ignition tube (3), an ignition composition box (4) and an insensitive ignition head (1), wherein one end of the fire transferring tube (2) is arranged on the insensitive ignition head (1) in coaxial threaded connection; the axis of the fire transferring tube (2) is vertical to the axis of the ignition tube (3); the other end of the fire transferring tube (2) is in coaxial threaded connection with the side wall of the ignition tube (3); and the ignition composition (6) is arranged at the inner part of the ignition tube (3). When the ignition device works, the insensitive ignition head (1) is detonated and ignited by utilizing ignition current; the generated fire is transferred into the ignition tube (3) through the fire transferring tube (2) to ignite the ignition composition (6) in the ignition tube (3); the ignition composition (6) rapidly burns beginning from the outside surface; the ignition composition box (4) is burned out by the fire; and main charge (5) is ignited. The separable ignition device has the advantages that the safety and the stability of the system are enhanced, and the sufficiency of main charge ignition is realized.

Description

technical field [0001] The invention relates to an ignition device, in particular to a detachable ignition device. Background technique [0002] There are three types of ignition devices used in missile rockets: ignition head, electric detonator and igniter. The igniter widely used at present is made up of igniter, igniter shell, ignition wire, and principle is to ignite igniter by ignition current, and the flame that igniter produces ignites the main charge of missile rocket again. The igniter has unstable factors such as misignition, and the main charge is not fully ignited, the initial burning area is small, the burning speed is low, and the burning is not complete. Contents of the invention [0003] The purpose of the present invention is to provide a detachable ignition device, which can solve the problems of misignition instability, small initial burning area, low burning speed and incomplete combustion of the main charge in current igniters. [0004] A detachable ...
