Embodiment Construction

[0052] A wide-angle multi-buffering deformation assembly landing support mechanism is composed of an opening mechanism and a span expansion mechanism. Both the expansion mechanism and the span expansion mechanism are set on the rocket body to provide a landing impact environment for the rocket. The landing support mechanism is used to ensure The aerodynamic shape of the ascent section of the rocket ensures the stability and long-span requirements of the rocket during the recovery and landing process of the rocket. The landing support mechanism can be recovered after the rocket lands.

[0053] like figure 1 , figure 2 As shown, a reusable foldable, large-span, multi-buffer launch vehicle landing support mechanism, including an expansion mechanism and a span expansion mechanism.

[0054] like Figure 3 to Figure 11 As shown, the opening mechanism includes a support, a mounting pin, a left and right shaft end baffle plate, a trunnion, a fixing ring, an opening mechanism spring...

Abstract

A wide-angle multi-buffering deformation assembly landing supporting mechanism is composed of an opening mechanism and a span expansion mechanism, the opening mechanism and the span expansion mechanism are both arranged on a rocket body and provide a landing impact environment for a rocket, and the landing supporting mechanism is used for guaranteeing the aerodynamic configuration of the rising section of the rocket and improving the safety of the rocket. And in the rocket recovery landing process, the large-span requirement of rocket stability is met, the landing supporting mechanism can be recovered after the rocket lands, the structure is simple, installation is convenient, and repeated use can be achieved.

Description

technical field [0001] The invention relates to a wide-angle multi-buffer deformation assembly landing support mechanism, which belongs to the field of landing buffer mechanism design. Background technique [0002] Recoverable launch vehicles have wide application prospects because they can significantly reduce launch costs. Existing rocket recovery technology can generally be divided into three types: parachute type, winged flyback type and vertical return type. The parachute recovery scheme requires the rocket itself to carry a parachute, which not only puts high requirements on the structural design of the rocket, but also is greatly affected by the atmospheric operation during the parachute; the flyback structure with wings is not only complicated in mechanical structure, but also The rocket itself is required to ignite and brake; the vertical return recovery scheme and the landing buffer device are directly related to the success or failure of the recovery mission. ...
