Liquid rocket recycling method

Abstract

The invention discloses a liquid rocket recycling method. A power tail cabin section of a liquid rocket is arranged in a first sub-stage in a detachable mode, wherein the power tail cabin section is separated from the first sub-stage after the first sub-stage of the rocket is separated. A parachute bag which is arranged in the power tail cabin section is opened, thus achieving the deceleration ofthe power tail cabin section, and the power tail cabin section can be recycled after landing. Compared with the prior art, the liquid rocket recycling method has the advantages of convenient control,safety and reliability, cost saving, convenient reuse and the like during the recycling process of the power tail cabin section.

Description

technical field [0001] The invention relates to the technical field of liquid rocket recovery, in particular to a liquid rocket recovery method. 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...
