Abstract

The invention relates to the field of manufacturing of aircrafts, and provides a manual jettisoning system of a landing gear. A first fan-shaped member is connected with an unlocking rocker arm of a left main landing gear uplock through a bracket, a second pulley, a second bracket pulley assembly, a fifth bracket pulley assembly, a second steel rope and a second fan-shaped member; the second fan-shaped member is connected with a jettisoning valve through a fifth steel rope, a sixth bracket pulley assembly, a seventh bracket pulley assembly and a bracket rocker arm assembly; the first fan-shaped member is connected with an unlocking rocker arm of a right main landing gear uplock through the bracket, a first pulley, a fourth bracket pulley assembly and a third steel rope, and is connected with an unlocking rocker arm of a front landing gear uplock through a third bracket pulley assembly, a first bracket pulley assembly, a fourth steel rope, an eighth bracket pulley assembly and a ninth bracket pulley assembly. According to the manual jettisoning system of the landing gear, the landing gear is emergently put down when a hydraulic system fails.

Description

technical field [0001] The invention relates to the field of aircraft manufacturing, in particular to a landing gear manual ejection system. Background technique [0002] Existing aircraft landing gear throwing systems mostly use hydraulic systems. Once the hydraulic system fails, the aircraft will not be able to lower the landing gear. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manual release system for the landing gear, which can drop the landing gear in an emergency when the hydraulic system fails. [0004] The technical scheme of the present invention is: a landing gear manual release system, comprising a landing gear manual release handle, a first steel cable, a second steel cable, a third steel cable, a fourth steel cable, a fifth steel cable, a A sector, a second sector, a bracket, a first pulley, a second pulley, a first bracket pulley assembly, a second bracket pulley assembly, a third pulley bra...
