Throwing separating mechanism for civil aircraft

Abstract

The invention belongs to the field of aviation safety design, and particularly relates to a throwing separating mechanism for a civil aircraft. In the prior art, a recorder and an aircraft body crash simultaneously in an aircraft accident. At present, most of existing domestic and overseas throwing separating mechanisms are used for military aircrafts. From consideration to life safety of people and flight safety of aircrafts, a throwing recorder which takes a large number of initiating explosive devices as power devices cannot meet requirements of civil aircrafts to throwing separating mechanisms of throwing type recorders. The invention provides the throwing separating mechanism used on the civil aircraft. The throwing separating mechanism used on the civil aircraft consists of a bottom cover, a base, a fixing clamp, a compression spring, a connecting flange, a steel ball, a fixing screw, a push shaft, a steel ball dropping groove and a driving component, is used for separating a throwing recording from an aircraft body before the aviation accident of the civil aircraft, and is simple in structure; and an energy source required for throwing separating action is small, so that damage to people and the aircraft is limited during throwing separating.

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...
