Problems solved by technology

[0004] This kind of vertical recovery technology of the rocket sub-stage has high requirements on the control of the attitude and speed of the rocket when it lands. If the attitude or speed of the rocket sub-stage is not well controlled, it is likely to cause the rocket to topple or explode, causing the rocket to fall. Recovery completely failed

Embodiment Construction

[0029] Various exemplary embodiments of the present invention will now be described in detail. The detailed description should not be considered as a limitation of the present invention, but rather as a more detailed description of certain aspects, features and embodiments of the present invention.

[0030] It will be apparent to those skilled in the art that various modifications and changes can be made in the specific embodiments of the present invention described herein without departing from the scope or spirit of the present invention. Other embodiments will be apparent to the skilled person from the description of the present invention. The specification and examples in this application are exemplary only.

[0031] The existing liquid rocket recovery technology needs to add, for example, 4 telescopic support legs to the rocket sub-stage, and equip it with a set of high-pressure gas actuating mechanism. Among them, the high-pressure gas actuating mechanism is used to dep...

Abstract

The present invention provides an auxiliary recovery system for carrier rocket recovery, comprising: a carrying platform, a side wall arranged on one side of the carrying platform and connected to the carrying platform, and a plurality of retractable device and a controller for controlling the start of the retractable device; the parts of the side walls facing each other are provided with a plurality of pairs of openings corresponding to each other, and at least one of each pair of openings corresponding to each other is equipped with the adjustable A telescopic device, the elongation length of which is greater than the distance between two corresponding openings after the telescopic device is activated. The auxiliary recovery system of the embodiment of the present invention can guide and limit the movement of the substage of the rocket to be recovered before it lands, avoiding its rollover or overturning during the landing process, and reducing the attitude requirements of the substage of the rocket to be recovered , improving the recovery success rate.

Description

technical field [0001] The invention relates to the technical field of rocket recovery, in particular to an auxiliary recovery system for launch vehicle recovery. Background technique [0002] Rocket recovery technology is a bright pearl in the field of aerospace technology and a comprehensive manifestation of the strength of aerospace technology. Therefore, it has also received great attention from various aerospace powers. At present, there is no liquid rocket recovery scheme that has been put into use in China. SpaceX and Blue Origin of the United States have successfully recovered rockets many times. For example, the rocket recovery technology scheme adopted by Space X in its recent launches is: during the landing process of the rocket sub-stage, the main engine is ignited to achieve deceleration, and at the same time, the attitude control engine is used to adjust the flight attitude of the rocket sub-stage, so that Make sure the rocket falls in a nearly vertical attit...
