Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations. Spatial relational terms such as "below", "below", "under", "low", "above", "above", "high", etc. are used to facilitate the description and explain that an element is relative to the first The positioning of two elements means that these terms are intended to cover different orientations of the device in addition to those different orientations shown in the figures. In addition, for example, "one element is above / under another element" may mean that two elements are in direct contact, or that there are other elements between the two elements. In addition, terms such as "first", "second", etc. are also used to describe various elements, regions, parts, etc., and should not be regarded as limitations. Similar terms refer to similar elements throughout the description.

Abstract

The invention provides a landing support mechanism for sub-stage rocket body recovery of a rocket. The landing supporting mechanism comprises an implanted leg device arranged on a rocket body landingend cabin section. The implanted leg device comprises a support cylinder and extending supporting legs; one end of the support cylinder is fixedly connected with the rocket body landing end cabin section, the other end of the support cylinder is elastically connected with the extending supporting legs; and a hard drilling tip is further arranged at the end, away from a rocket body, of each extending supporting leg. When the rocket body lands, the extending supporting legs provided with the hard drilling tips are inserted into the surface of the landing area, so that stable landing of the rocket body is guaranteed. The landing supporting mechanism is assembled at the landing end of the liquid rocket; when the rocket body lands, the implanted leg device is inserted into the surface of the landing area, so that the rocket body can be prevented from toppling over while the first-stage rocket body is decelerated and damped, the rocket body recycling success rate and stability are improved,and the rocket body can be repeatedly used conveniently.

Description

Technical field [0001] The invention relates to the technical field of rocket recovery, in particular to a landing support mechanism and a liquid rocket used for the recovery of rocket sub-level rocket bodies. Background technique [0002] With the rapid development of the aerospace industry, various technologies involving rockets have also achieved rapid progress. At present, as the only vehicle for launching satellites into space, the continuous reduction of rocket manufacturing and launch costs is the goal pursued by major commercial aerospace companies. [0003] Take rocket recovery as an example. The current mainstream rocket recovery method is based on the reverse thrust landing method represented by Space X and Blue Origin. That is, by adding landing legs on the rocket body, the engine at the bottom of the rocket body ignites multiple times when it is close to the ground, and the thrust of the rocket is changed by the engine, and the rocket position is adjusted to achieve l...
