Abstract

The invention discloses a large-span foldable reusable rocket landing buffer structure, which comprises a main leg (1), two subsidiary legs (2) and a landing plate (3), wherein an upper joint at one end of the main leg (1) and an upper joint at one end of each subsidiary leg (2) are connected with a mounting seat of a rocket body through knuckle bearings arranged on the main leg (1) and the subsidiary legs (2) respectively, and the knuckle bearings are arranged on the upper joints and the lower joints of the main leg (1) and the subsidiary legs (2); a rotating shaft is arranged on one side ofthe landing plate (3); the lower joint at the other end of the main leg (1) and the lower joint at the other end of each subsidiary leg (2) are connected to the same rotating shaft on the landing plate (3) through knuckle bearings arranged on the main leg (1) and the subsidiary legs (2) respectively; and a rubber buffer pad is arranged on the other side of the landing plate (3) and can make buffercontact with the ground when the rocket lands slowly.

Description

technical field [0001] The invention relates to a large-span, foldable and reusable rocket landing buffer structure, which belongs to the technical field of mechanical combination load-bearing buffer devices with high light weight, high efficiency and good operability. Background technique [0002] The launch vehicle is the main tool for human beings to enter space. The high launch cost limits the development and utilization of space for human beings. The one-time use of the launch vehicle is the main reason for the high launch cost. Therefore, the reuse of launch vehicles is of great significance for reducing launch costs and improving the ability of humans to enter space. For the vertical round-trip reusable launch vehicle, the landing process is the last step of the return of the launch vehicle, and it is also the key to the overall plan of the rocket's vertical return technology. A large-span, foldable landing buffer structure for reusable rockets is designed, which can...
