Embodiment Construction

[0045] 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.

[0046] 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.

[0047] 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 rocket recovery device and a liquid rocket. The rocket recovery device comprises a fixing seat, N supporting structures and M hanging frame structures, the supporting structures are evenly distributed in the circumferential direction and fixedly arranged on the fixing seat, the bottom ends of the supporting structures are fixedly connected with the fixing seat, the top endof each supporting structure is connected with one end of the corresponding hanging frame structure through a rotating structure, the other ends of the plurality of hanging frame structures extend towards the direction in which the hanging frame structures are close to each other, the hanging frame structures are used for moving downwards along with a rocket to be recovered through the rotating structures after making contact with the rocket to be recovered so as to buffer the acting force of the rocket to be recovered in the landing process and fix the rocket to be recovered, and rocket recovery is achieved. According to the rocket recovery device and the rocket, hanging lock mechanisms are connected with the hanging frame structures on the liquid rocket so as to capture the rocket to berecovered, the requirements for the posture and speed of rocket recovery can be lowered, and the success rate of rocket recovery is increased.

Description

technical field [0001] The invention relates to the technical field of rocket recovery, in particular to a rocket recovery device and a liquid rocket. 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. As t...
