Problems solved by technology

[0003] At present, most of the unlocking and separating mechanisms used for the release recorder at home and abroad use pyrotechnics as the power source. Due to the use of pyrotechnics, the explosion energy is large and the speed is fast, which is not conducive to the maintenance of the release recorder and the flight safety of the aircraft.

Abstract

The embodiment of the invention provides a novel unlocking separation mechanism, and belongs to the technical field of avionics. The novel unlocking separation mechanism specifically comprises a base,a recorder connecting seat and a spring unlocking mechanism, wherein the base is of a hollow tubular structure, one end of the base is provided with a shape memory alloy power source, and the side wall of the other end of the base is circumferentially provided with a plurality of first through holes; the recorder connecting seat is used for fixing a throwing recorder, and second through holes areformed in the positions, corresponding to the first through holes, of the side wall of the recorder connecting seat in the circumferential direction; and the spring unlocking mechanism comprises a thrust spring arranged on the outer wall of the base in a sleeving mode and a limiting steel ball used for limiting and locking the recorder connecting seat and the base. The novel unlocking separationmechanism can separate the throwing recorder from an aircraft body at the key moment of aircraft accidents, so that the throwing recorder escapes from the severe crash environment, and the survival capacity of the throwing recorder is improved.

Description

technical field [0001] The present disclosure relates to the technical field of avionics, in particular to a novel unlocking and separating mechanism. Background technique [0002] With the rapid development of aviation technology, more accidents such as plane crashes have occurred, which put forward higher requirements for the survival rate of the recorder. The fixed recorder does not have the ability to float in the sea, and the recorder is difficult to search and the salvage period is long. The problem of high cost. The drop recorder is a device that can improve the recovery efficiency of the recorder after a helicopter crash. When the helicopter crashes, it is separated from the body, lands or falls into the water after deceleration, can float on the water, and automatically completes the positioning, which is convenient for search personnel to quickly find the recorder. location, implement salvage. [0003] At present, most of the unlocking and separating mechanisms u...
