Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] It should be noted that all directional indications (such as up, down, left, right, front, back, forward, reverse...) in the embodiments of the present invention are only used to explain the position of each direction in a certain posture (as shown in the figure). If the relative positional relationship, movement conditions, etc. between the components change, the directional indication will also change accordingly.

[0041] In addition, in the...

Abstract

The invention discloses a non-rebound aircraft landing buffer system and a non-rebound aircraft landing method. The landing buffer system comprises an aircraft, an air bag, a landing bottom plate, a rope and a rope control mechanism. The landing bottom plate is detachably arranged at the bottom of the aircraft; the rope control mechanism comprises a rotating shaft, an energy storage assembly and a limiting assembly, the rotating shaft is rotationally connected to the aircraft, one end of the rope is fixedly connected with the landing bottom plate, and the other end of the rope is wound around the rotating shaft so as to drive the rotating shaft to rotate forwards when the landing bottom plate falls; the energy storage assembly is arranged on the rotating shaft so as to store energy when the rotating shaft rotates forwards and release energy to drive the rotating shaft to rotate reversely to recycle the rope in a winding mode after the landing bottom plate lands; and the limiting assembly is arranged on the rotating shaft so as to limit the rotating shaft after the landing bottom plate lands, and the rotating shaft can only rotate reversely. The system and the method are applied to the field of aircraft recovery, can effectively avoid hard landing and rebound of aircrafts in the use process, ensures safe landing of the aircrafts, has good universality, and can adapt to various terrains.

Description

technical field [0001] The invention relates to the technical field of aircraft recovery, in particular to a non-rebound aircraft landing buffer system and an aircraft non-rebound landing method. Background technique [0002] Recycling technology is an important technical field in aerospace engineering. With the development of the aerospace industry, the research on the safety recovery technology of aircraft is getting deeper and deeper. The buffer airbag device has the characteristics of small size, light weight, low cost, simple structure, reliable performance, and good stability, so it is widely used in the fields of equipment airdrop and aircraft landing buffer. [0003] Although the airbag structure is various, the existing airbag devices all have the problems of rebound or hard landing during use, which will bring hazards such as uncontrollable attitude of the aircraft (such as rolling, toppling), secondary impacts and the like. For the airbag cushioning system, no h...
