Embodiment Construction

[0013] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention, specifically as follows:

[0014] see figure 1 , this embodiment is mainly composed of four sets of vertical landing support structures, which are symmetrically installed at the bottom of the first-stage engine of the launch vehicle. Wherein, each set of supporting mechanisms includes a separate rocket shell 1, landing legs 2, telescopic rods 3, supporting feet 4, hydraulic control devices 5, guide rails 6, and locking mechanisms 7. The upper end of the separated rocket shell 1 is hinged to the head of the guide rail 6, the upper end of the hydraulic control device 5 is hinged to the landing leg 2, and the lower end of the hydraulic control device 5 is connected to the lower end of the carrier rocket body with a fixed hinge. Wherein, a guide rail 6 is provided inside the rocket b...

Abstract

The invention relates to a reusable carrier rocket vertical landing recovery support mechanism which can ensure that an aerodynamic shape of a reusable carrier rocket at an ascending stage is not affected, and the carrying performance of the reusable carrier rocket is improved. The support mechanism comprises four groups of vertical landing support structures; each group of vertical landing support structure comprises a detached rocket housing, landing legs, telescopic poles, supporting feet, hydraulic control devices, a guide rail and a locking mechanism. At the ascending stage of the reusable carrier rocket, the landing legs, the telescopic poles, the supporting feet and the hydraulic control devices are folded into the detached rocket housing. In the recovery landing process, the detached rocket housing and the landing legs are unfolded downwards under the action of the hydraulic control devices; therefore, the stable support of vertical landing of the carrier rocket is realized. The invention provides a novel reusable carrier rocket vertical landing recovery support structure design scheme, by adopting the support mechanism, stable and reliable vertical landing support of a rocket body of the carrier rocket is realized under the condition that the aerodynamic shape of an original carrier rocket is not affected, and the support mechanism can be used for multiple times, and has a certain practical value.

Description

technical field [0001] The invention relates to the field of recovery of a reusable carrier rocket, in particular to a novel retractable carrier rocket vertical recovery landing support mechanism that does not affect the aerodynamic shape of the ascent section of the carrier rocket. Background technique [0002] The vertical take-off and landing reusable launch vehicle is based on mature launch vehicle technology, and the landing device is added to realize the vertical recovery of the launch vehicle. After simple maintenance and propellant replenishment, the recovered launch vehicle can be quickly put into the next launch, thus Realizing the reusability of the launch vehicle, the vertical take-off and landing reusable launch vehicle can greatly reduce the single flight cost of the launch vehicle, which is an important direction for the development of space launch vehicles. The landing mechanism is the key and core component of the vertical landing and recovery of the launch ...
