Shearing type air supply mechanism of refrigeration device for infrared missile

Abstract

The invention provides a shearing type air supply mechanism of a refrigeration device for an infrared missile. The shearing type air supply mechanism of the refrigeration device for the infrared missile comprises an air supply pipeline, a spherical joint, a locking nut, an air supply nozzle joint and an air supply nozzle body, wherein the air supply pipeline is connected with the spherical joint, the spherical joint is connected with the air supply nozzle joint, the locking nut is in threaded connection with the upper part of the air supply nozzle joint, the locking nut tightly presses the spherical joint, and the lower end of the air supply nozzle joint is fixedly connected with the air supply nozzle body; and the lower end part of the air supply nozzle body is partially embedded into the missile, and the air supply nozzle body is provided with a shearing stress groove with the outer surface of the missile as a boundary. When the missile is launched, the air supply mechanism and the missile are reliably separated in a shearing mode, so that the reliability and safety of the missile launching are improved.

Description

technical field [0001] The invention relates to a missile refrigeration device, in particular to a shearing air supply mechanism of an infrared missile refrigeration device. Background technique [0002] The cooling air supply device of traditional infrared missiles is installed in the missile cabin, which occupies the equipment installation space of the missile cabin, increases the weight of the missile, and affects the technical performance of the missile. In order to reduce the weight of the missile, increase the range of the missile and reserve enough equipment installation space for upgrading the electronic equipment of the missile, the cooling air supply device is arranged on the launch tube. Before the missile is launched, the cooling air supply device of the launch tube provides high-pressure cooling gas to cool the core components of the missile's seeker. When the missile is ignited and launched, the cooling air supply device needs to be separated from the missile ...
