Modeling and research of a multi-stage parachute system for the booster recovery

Abstract

With the development of the aerospace technology, reducing the cost of exploring space has become the target of most countries. The recovery of rocket boosters is regarded as one of the most effective solutions to this problem. A whole recovery scheme of the drag parachute and controllable parafoil for accurate landing is designed in this paper, in view of the high reliability and low cost of the parachute recovery system. The models of the parachute-payload in the deceleration stage and the parafoil-payload in the gliding stage are established. On the basis of the high-fidelity models, the motion characteristics of the whole recovery process are simulated considering the external disturbances and internal disturbances such as the turbulent wind and angle uncertainty. This work provides the parameter reference for the accurate recovery control of the booster.

A novel dynamics modeling method for the heavy cargo airdrop based on reduced multibody system transfer matrix method

“…Purvis [6], Zhang [7] and Tang [8] considered the suspension lines as mass spring damping model to simulate the deployment phase for space vehicle recovery system. Xing [9] established a multi-stage parachute system model for the booster recovery. Ning [10] established a high-fidelity dynamics model for the heavy cargo airdrop and developed 3D visualization software based on Blender.…”
