Abstract

The invention provides a buffer structure, a buffer energy-absorbing recovery device and an aircraft. The buffer structure comprises: a honeycomb core having a plurality of accommodating holes for accommodating residual parts of explosion bolts during the stage separation process of the aircraft, a first panel and a second panel, wherein the honeycomb core is arranged between the first panel and the second panel; cross-sections of the first panel and the second panel and the honeycomb core are designed in shape; and during the stage separation stage of the aircraft, the buffer structure can absorb the energy of the residual parts of the explosion bolts through self moulding and deformation. The technical solution of the buffer structure is applied to solve the technical problem that the prior art cannot safely and reliably recover the separated parts with high hazardness of the explosion bolts.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a buffer structure, a buffer energy absorption recovery device and an aircraft. Background technique [0002] During the separation process of the hypersonic vehicle, the huge explosion can push the remnants of the explosive bolts to advance at a relatively high speed, generally up to 30m / s. The impact of high momentum will cause damage to the structure of the projectile and the equipment in the cabin. In order to avoid such damage during the separation process, a buffer recovery device must be installed in the cabin to buffer and recover the separated remnants. The recovery device must have the characteristics of safety, reliability and stability. However, in the prior art, material fracture is usually used as an energy-absorbing method. This method cannot safely and reliably recover the highly harmful detached parts of the explosive bolt, which greatly reduces the safety perfo...
