A large-load flexible and controllable landing buffer device and method

Abstract

The invention discloses a large-load flexibility-controllable landing buffering device and method. Due to the combination of an air bottle set, charging and exhausting valves, electric explosion valves, filters, pressure monitoring devices, diverters and buffering air bags, landing buffering of a new-generation multi-purpose airship re-entry capsule is achieved, and the buffering capability reaches the magnitude of 7000 kg; switching of the landing work modes of the re-entry capsule in two landing environments is achieved, and adaptability of the air bag landing buffering device to the highland low-pressure environment condition and the slope environment condition is improved; initiative control over the buffering process is achieved, and the landing buffering overload can be controlled in the required range; and a rollover preventing function and a toppling preventing function of the re-entry capsule in the landing process are achieved.

Description

Technical field [0001] The invention relates to a large-load flexible and controllable landing buffer device and method, belonging to the technical field of landing buffers for aerospace vehicles. Background technique [0002] When the new generation multi-purpose spacecraft is landing on the return module, it is necessary to carry out landing buffer protection for the return module to reduce the landing overload of the return module and protect the safety of the astronauts. Therefore, the landing buffer device of the return cabin of the multi-purpose spacecraft is one of the key technologies. [0003] Commonly used landing buffer devices include reverse thrust rockets, landing legs, and buffer airbags. Reverse rockets and landing legs have been more developed for the landing buffer of the return module of the new generation of multi-purpose spacecraft, so they are not suitable for the landing buffer of the return module of the new generation of multi-purpose spacecraft. Because ...
