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 liquid rocket, comprising a sub-stage rocket, wherein the end of the sub-stage rocket away from the main engine includes an attitude adjustment mechanism and a padlock mechanism; the attitude adjustment mechanism is used to adjust the landing attitude of the sub-stage rocket when the sub-stage rocket returns, so that The padlock mechanism is connected to the hanger structure in the ground rocket recovery device; the padlock mechanism includes a mounting frame, a hanging rod, a switch mechanism, a main padlock, a secondary padlock and a hanging rod holder, and the mounting frame is fixedly arranged on the sub-stage rocket. The installation frame is fixedly connected, and the other end is connected to the bracket of the hanging rod through the switch mechanism. The main padlock is arranged on the surface of the sub-stage rocket in the circumferential direction, one end of the auxiliary padlock is fixedly connected to the mounting frame, and the other end runs through the hanging rod in the axial direction Afterwards, it is fixedly connected with the main padlock. The rocket recovery device and the rocket of the present invention are connected to the pylon structure on the liquid rocket through the padlock mechanism to capture the rocket to be recovered, which can reduce the attitude and speed requirements for rocket recovery and improve the success rate of rocket recovery.

Description

technical field [0001] The invention relates to the technical field of rocket recovery, in particular to 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 the falling rocket sub-stage app...
