Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0017] Such as figure 1 As shown, it is a schematic diagram of the installation position of the engine variable thrust baffle and the release mechanism. The rear part of the baffle 8 is installed by a rotating shaft and can be turned over; the front end is located at the nozzle of the nozzle 10 of the engine 11; the release mechanism 9 of the present invention is installed The middle part of the baffle 8 can realize locking and release of the baffle 8 .

[0018] As shown in 2(a) and 2(b), the release mechanism 9 of the present invention includes a locking pin 1, a release pin 2, a screw 3, a pin spring 4, an electric squib 5, a support 6 and a release spring 7.

[0019] The support 6 is installed close to the lower surface of the baffle 8, and there are two inner passages perpendicular to each other inside the support 6: the first passage in the shape of ...

Abstract

The invention discloses a releasing mechanism of an engine flow baffle. A simple pin connection structure is adopted so that the connection is stable and reliable, the fact that the locking and releasing process is simple and easy to operate is ensured, by detonating two electric ignition tubes to eject pins, the release of the flow baffle is realized quickly, the accurate and rapid control effectis achieved, and the releasing mechanism gets success through multiple ground testing.

Description

technical field [0001] The invention belongs to the technical field of solid rocket motors, and in particular relates to a release mechanism for a motor baffle. Background technique [0002] The spacecraft is the first manned spacecraft developed by our country, and the first thing is to ensure the personal safety of the astronauts. The task of the escape system is to take the return capsule with the astronauts out of the danger zone when the launch vehicle fails, and provide the necessary conditions for the separation of the return capsule and the escape vehicle. The escape system includes four yaw and pitch engines. The task of the yaw and pitch engines is to provide power for the escape system to deviate from a certain horizontal distance and to deviate from the launch vehicle orbit when the escape tower separates when the rocket escapes. Its biggest feature is that variable thrust baffle devices are installed at the outlets of the engine nozzles, so that the yaw and pit...
