Parachuting type recovery method used for first-stage rocket body recovery

Abstract

The invention provides a parachuting type recovery method used for first-stage rocket body recovery. The parachuting type recovery method comprises the following steps that after a first-stage rocketbody and a second-stage rocket body are separated, the first-stage rocket body is turned over to the state that a separation cabin section is located above a lower power cabin section; a parachuting structure arranged on the power cabin section of the first-stage rocket body is opened to decelerate the first-stage rocket body; the sliding direction of the first-stage rocket body is controlled, sothat the first-stage rocket body flies to the position above the landing area; and when the first-stage rocket body lands, an implantation leg device is inserted into the surface of the landing area,and a landing stability augmentation support is flatly laid and unfolded along the surface of the landing area, so that the first-stage rocket body lands stably and recovery is completed. According tothe parachuting type recovery method used for first-stage rocket body recovery, the first-stage rocket body is turned over to the state that the separation cabin section faces downwards after being separated, then the parachuting structure is opened for speed reduction, the landing posture and direction of the rocket body are adjusted in real time, when the rocket body lands, the implantation legdevice is inserted into the landing area, and meanwhile the landing stability augmentation support is flatly laid and unfolded along the surface of the landing area, and therefore the first-stage rocket body lands stably and recovery is completed.

Description

technical field [0001] The invention relates to the technical field of rocket recovery, in particular to a parachute recovery method for recovery of a first-stage rocket body. 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 rocket body recovery method is mainly the reverse thrust landing method represented by American Space X and Blue Origin. That is, by adding landing legs to the rocket body, the engine at the bottom of the rocket body is ignited multiple times when it is close to the ground, and the thrust is changed by the engine, and the position of the rocket is adjusted to achieve landing and fixed-poi...
