Air spring slow-releasing mechanism

Abstract

The invention discloses an air reed type slow release mechanism which can improve the reliability of launching a rocket. The air reed type slow release mechanism comprises a gas supply system (1), a slow release cylinder (2), a traction cylinder (3), a soleplate (4), a traction arm (5), a swinging lever (6) and a lever arm (7); the soleplate (4) is connected with a rocket launching pad; the lever arm (7) is fixed on the soleplate (4); the lower ends of the slow release cylinder (2) and the traction cylinder (3) are movably fixed on the soleplate (4) respectively; the upper end of the slow release cylinder (2) is movably connected with the lever arm (7); the upper end of the traction cylinder (3) is connected with the lower end of the traction arm (5); the upper end of the traction arm (5) is fixedly connected with the swinging lever (6); the other end of the swinging lever (6) is movably connected with the lever arm (7); and the gas supply system (1) provides high-pressure gas for the slow release cylinder (2) and the traction cylinder (3). The mechanism can meet the requirement of traction load of 180 KN and can achieve the function of slow release after the rocket is launched.

Description

technical field [0001] The invention belongs to the technical field of rocket launch, and in particular relates to a gas spring type slow release mechanism for improving the reliability and economy of rocket launch and ensuring the safety of the launch site. Background technique [0002] my country has begun to develop a new generation of non-toxic and non-polluting launch vehicles for launching large-tonnage satellites, among which the slow release technology is one of the difficulties in the development. [0003] The pinning and slow release device is installed at the connection and fixed part between the rocket and the launch pad, and is an essential facility for the rocket to realize the pinning and slow release launch mode. When a rocket is launched in the past, before the rocket is released from the launch pad, the thrust generated by the rocket engine reaches a predetermined value and then the rocket is released. The impact generated by the sudden release of large thr...

Problems solved by technology

The United States uses the slow-release force generated by the plastic deformation of the pull pin to slowly release the rocket, but the slow-release pin has the characteristics of unstable slow-release force; France uses a hydraulic system slow-release mechanism, but the device has complex systems, etc. features

[0005] In China, the research on this technology starts relatively late, and there is no relevant research report and application
