Gas flow independent discharge structure suitable for guided missile canister launcher

Abstract

The invention provides a gas flow independent discharge structure suitable for a guided missile canister launcher. The structure comprises an inner cylinder body (10), an outer cylinder body (20), a fixed flow guide plate (30) and a movable flow guide plate (40). A first gas channel (11) and a second gas channel (21) are arranged among the fixed flow guide plate (30), the inner cylinder body (10)and the outer cylinder body (20), through the fixed flow guide plate (30), a gas flow (50) is changed to be discharged from the first gas channel (11) and the second gas channel (21) from the second gas channel (21) previously, the space between a guided missile (60) and the inner cylinder body (10) is effectively used, the gas flow (50) can be effectively discharged and guided, the guided missile(60) can be prevented from being burnt out, the gas flow (50) discharged from the second gas channel (21) can be reduced, the whole design size of the guided missile canister launcher is reduced, andthe space adaptation of the guided missile canister launcher is improved.

Description

technical field [0001] The invention relates to the technical field of missile launch for weapon equipment systems, in particular to a self-discharge structure of gas flow suitable for missile launch tubes. Background technique [0002] As the core technology for launching medium and long-range tactical missiles, the self-discharging launch tube has attracted more and more attention from all countries in the world with its independent gas self-guiding launch method. At present, the self-discharging launch tube mainly consists of an inner cylinder and an outer cylinder. Composition, the inner cylinder and the outer cylinder communicate with each other at the tail of the self-discharging launch tube, and the reversal of the wake is realized through the diversion cone and the rear cover. However, in actual use, missiles generally have airfoils and air rudders, resulting in an excessively large inner cylinder. When the overall size of the self-discharging launch tube is limited,...
