Carrier rocket sub-stage recycling system and method

Abstract

The invention discloses a carrier rocket sub-stage recycling system and method. The carrier rocket sub-stage recycling system comprises a recycling box body, a probe device, a signal transceiver, a plurality of airbags, an inflation device, moving mechanisms and a ground control system. The recycling box body is of a U-shaped box body structure with the top end being not closed; the probe device,the signal transceiver and the inflation device are arranged on the recycling box body; the multiple airbags are arranged at the bottom and on the side faces of the recycling box body correspondingly;the inflation device is connected with the multiple airbags; the moving mechanisms are arranged at the bottom of the recycling box body; and the ground control system makes remote communication withthe carrier rocket sub-stage recycling system through the signal transceiver. Based on a carrier rocket in active service, recycling of a sub-stage part is completed while the carrier rocket sub-stagepart is less changed.

Description

technical field [0001] The invention belongs to the technical field of aircraft systems, and in particular relates to a recovery system and method for a carrier rocket sub-stage. Background technique [0002] In order to reduce the launch cost of launch vehicles, recycling and reusing launch vehicle sub-stages has become an important technical route in the exploration and development process of various countries in the field of aircraft systems. The US SPACEX company has successfully realized the sea and land recovery and reuse of the first stage of the launch vehicle, which proves the feasibility of the recovery and reuse technology route. [0003] At present, the commonly used methods of recovery of the sub-stage of the launch vehicle are: parachute recovery or vertical recovery with a drop bracket. Both the parachute and the landing bracket are installed on the sub-stage of the launch vehicle, which increases the weight of the sub-stage of the launch vehicle, reduces the...

AI Technical Summary

Problems solved by technology

Both the parachute and the landing bracket are installed on the sub-stage of the launch vehicle, which increases the weight of the sub-stage of the launch vehicle, reduces the payload of the sub-stage of the launch vehicle, and changes the aerodynamic shape of the rocket to a large extent, increasing the risk during flight
