摘要
火星探测器伞系减速的主要特点包括火星特殊的环境、特殊的任务需求以及特殊的开伞条件.天问一号伞系减速分系统采用了直接弹伞的一级减速方案、超音速锯齿形盘缝带伞、低冲击高速弹伞筒,以及被动分离的轻型多功能筒盖等技术方案,以流固耦合仿真为代表的多项仿真、以重载直升机空投试验、火箭平台的高空开伞试验为代表的大量的研制试验,对减速方案进行了充分有效的验证.2021年5月15日,天问一号火星探测器成功着陆火星,伞系减速分系统各项飞行数据与预期相符.
The main parameters of the parachute deceleration system for the Mars probe include the special environment,mission requirements,and parachute opening conditions.The parachute deceleration subsystem of the Tianwen-1 Mars probe includes one parachute for deceleration,one motor deployment system,and one passive separation apex cap.The parachute deceleration subsystem has been fully and effectively verified by fluid-structure interaction(FSI)simulations,airdrop tests,and high-altitude parachute opening tests.On May 15,2021,Tianwen-1 successfully landed on Mars,and all flight data of the parachute deceleration subsystem were in line with expectations.
