Canopy jettison experiment device and system and canopy

Abstract

The invention discloses a canopy jettison experiment device and system and a canopy. The canopy jettison experiment device comprises a mounting platform, a folding corn control component, a supporting component, a release device and a jettison power device, the folding corner control component is arranged on a mounting face and used for containing one end of the canopy, the canopy can rotate around the folding corner control component, the supporting component is arranged on the mounting face and supports the canopy, and the release device is arranged on the mounting platform; the jettison power device comprises a power member, one end of the power member is fixed while the other end of the same is connected with the release device, the power member can be in a fixed state and in a moving stage, and the power member has preset force and is stationary in the fixed state and release the preset force and is driven by the preset force to move in the moving state. By adopting the canopy jettison experiment device, an existing experiment verification means can be replaced at a scheme design stage before specific design work is conducted to perform preliminary experiment verification on performance of newly-developed life-saving system jettison canopies.

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to a canopy throwing test device, a canopy throwing test system and a canopy. Background technique [0002] There are two main ways to test and verify the performance of the existing aircraft lifesaving system by throwing the canopy to clear the ejection channel: one is to use a test bench that simulates the structure of the aircraft cockpit, install the canopy throwing system, and throw the real canopy or A simulated canopy with the same weight and center of gravity as the real canopy; the second is to directly use the real aircraft fuselage structure and throwing system to throw the real canopy. Both methods require the manufacture of corresponding test systems and equipment before they can start Test verification. According to the requirements of the "dumping test", the ground static test needs to be carried out 10 to 14 times during the development of the ditching syst...

AI Technical Summary

Problems solved by technology

Therefore there are the following two problems: a, high cost of testing

Because it is impossible to verify the key design parameters and actual working effects before the detailed design of the system is carried out, the life-saving system under test has a low technical maturity, which makes the test process have many uncertain factors. Adjust the life-saving system design plan and The cycle of repeated test verification is longer
