Abstract

The invention discloses a liquid rocket. The liquid rocket comprises a first sub-stage of the rocket, a power tail cabin section, a parachute bag and an explosion separation structure, wherein the power tail cabin section is connected with the first sub-stage of the rocket through the explosion separation structure; an explosion separation surface is positioned between the bottom of a storage tankof the first sub-stage of the rocket and the power tail cabin section; the parachute bag is arranged on the power tail cabin section in a folding manner; after separation of the first sub-stage of the rocket, the explosion separation structure is detonated, so that the power tail cabin section is separated from the bottom of the storage tank along the explosion separation surface; and the parachute bag is opened to reduce the descending speed of the power tail cabin section. Compared with the prior art, the structure has the advantages of convenience in control, safety, reliability, low costand the like; and after the power tail cabin section is recycled, the power tail cabin section can be overhauled, tested, cleaned and reused.

Description

technical field [0001] The invention relates to the field of liquid rocket engines, in particular to a liquid rocket. Background technique [0002] With the rapid development of the aerospace industry, various technologies related to rockets have also achieved rapid progress. At present, as the only vehicle for launching satellites into space, continuous reduction of rocket manufacturing and launch costs is the goal pursued by major commercial aerospace companies. [0003] Taking rocket recovery as an example, the current mainstream liquid rocket recovery method is the reverse thrust landing method represented by American SpaceX and Blue Origin. That is, by adding landing legs to the rocket body, the engine at the bottom of the rocket body is re-ignited when it is close to the ground, and the thrust of the engine is changed to adjust the position of the rocket to achieve landing and fixed-point landing, thereby completing the recovery of the first sub-stage of the rocket. ...
