摘要：
Developing the cluster parachute deceleration landing system is a key to realize the requirements of efficient deceleration and lossless landing of heavy-duty spacecraft. Based on aerodynamic theory, simulation analysis was performed on aerodynamic performance of single parachute in the parachute system. Taking simulation results as a reference, the configuration design of large ring sail umbrella was optimized..Based on the correctness and convergence of the simulation method, the cluster parachute system with multiple single parachute configurations was regarded as a research object, the aerodynamic resistance performance and attitude stability of the parachute system when the canopy is full were studied Through the flow field analysis and data comparison of the simulation results, it is found that the parachute with window and gap can not only ensure the good resistance characteristics of the cluster parachute system, but also maintain the working stability of the parachute system. This design can avoid the collision between single parachute due to force. © 2022, NUDT Press. All right reserved.
