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

[0023] 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.

[0024] 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.

[0025] 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 invention provides a recovery apparatus for a space launch vehicle. The recovery apparatus comprises a movable recovery platform, an actuating mechanism, auxiliary supporting structure s and a controller for controlling the actuating mechanism to be turned on or turned off. The movable platform is movably arranged in a range of a rocket recovery field, the auxiliary supporting structures are arranged on the movable platform, and after being started, the actuating mechanism is used for driving the auxiliary supporting structures to execute the auxiliary support for a to-be-recovered rocket.By adopting the recovery apparatus of the invention, the landing to-be-recovered rocket can be automatically supported in an assisting manner, the falling and rollover of the to-be-recovered rocket can be avoided, and the recovery success rate of the rocket can be increased.

Description

technical field [0001] The invention relates to the technical field of rocket recovery, in particular to a recovery device for space vehicles. 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 attitude. When the falli...
