Problems solved by technology

[0004] It is difficult to align the time when the camera takes pictures and the information collected by the sensor, and the trajectory of the center of gravity when the canopy is thrown, the state changes of various parts of the canopy and its throwing system, and the linkage between the mechanical actuation parts cannot be established. Accurate correlation in terms of time, and the process of canopy throwing involves high pressure and short time, so it cannot be accurately aligned in time, and it is very easy to have a great impact on the analysis of subsequent canopy throwing performance

Abstract

The invention relates to an aircraft canopy jettisoning test system, and the system comprises a canopy which is provided with a jettisoning system; a time mark lamp arranged close to the canopy; a camera which can continuously shoot images of the canopy and the time mark lamp; a plurality of sensors arranged at each information acquisition part on the canopy and the jettisoning system of the canopy; a plurality of voltage signal output devices which are connected with each mechanical action part on the seat cabin cover and the throwing system of the seat cabin cover and can output voltage signals, wherein the output voltage signals jump when mechanical actions occur at the corresponding mechanical action parts; and a data acquisition system which is connected with each sensor, each voltage signal output device, the jettisoning system, the time mark lamp and the camera, can receive information acquired by each sensor and voltage signals output by each voltage signal output device, and can control the jettisoning system to start at set time intervals after the camera is controlled to start and control the time mark lamp to be turned on. In addition, the invention relates to an aircraft canopy jettisoning test analysis method.

Description

technical field [0001] The application belongs to the technical field of aircraft canopy drop test, and in particular relates to an aircraft canopy drop test system and an analysis method thereof. Background technique [0002] When the aircraft is in a dangerous situation and cannot be recovered, the pilot in the cockpit will use the ejection life-saving method to escape, and throwing the canopy through the throwing system is the first step in ejection life-saving. [0003] Carry out the canopy throwing test, and study the trajectory of the center of gravity of the canopy throwing, the state changes of various parts of the canopy and its throwing system, and the linkage relationship between the mechanical actuating parts during the canopy throwing process, which can be used for the canopy The design and improvement of the canopy and its throwing system provide data support, in which the trajectory of the center of gravity of the canopy throwing is determined through the pict...
