A civil aircraft jettison separation mechanism

Abstract

The invention belongs to the field of aviation safety design, and in particular relates to a throwing and separating mechanism of a civil aircraft. In the prior art, when an aircraft crashes, the recorder and the aircraft body crash simultaneously. Most of the existing throwing and separating mechanisms both at home and abroad are used for military aircraft. For the consideration of personnel safety and aircraft flight safety, the ejection recorder with a large amount of explosives as the power device cannot meet the requirements of civil aircraft for the ejection separation mechanism of the ejection recorder. The invention provides a throwing and separating mechanism for civil aircraft, which is composed of a bottom cover, a base, a fixing clip, a compression spring, a connecting flange, a steel ball, a fixing screw, a push shaft, a steel ball drop groove and a driving part, and is used for The release recorder is separated from the aircraft body before the crash of a civil aircraft. Its structure is simple, the energy source required for the release and separation action is small, and the damage to personnel and the aircraft is limited during the release and separation.

Description

technical field [0001] The invention belongs to the field of aviation safety design, and in particular relates to a throwing and separating mechanism of a civil aircraft. Background technique [0002] In the prior art, when an aircraft crashes, the recorder and the aircraft body crash simultaneously. [0003] At present, most of the existing throwing and separating mechanisms at home and abroad are used in military aircraft. For the requirements of military aircraft on the timing of throwing and separating, pyrotechnics are mostly used as the power device of the throwing and separating mechanism. It has the advantages of fast separation speed and thorough separation. However, due to the use of a large number of pyrotechnics, the explosion energy is large and the speed is fast, which may cause greater damage to passengers on board, ground maintenance personnel and the aircraft body. The release recorder with pyrotechnics as the power device cannot meet the requirements of c...
