平流层浮空器快速部署平台的建模与仿真

针对目前平流层浮空器的部署方案中存在着放飞条件限制较多、升空过程中风险较大和部署时间较长等风险和不足，基于弾载弹射技术提出一种新型浮空器快速部署方案。该方案通过运载器将部署平台投放到预定空域，系统经过分离、减速伞减速、空中充气、展开等阶段，完成浮空平台的快速部署。通过分析系统构成和工作流程，建立了能够反映充气展开过程中，伞-艇-充气机构相互作用的多体动力学模型，并通过仿真计算校验了系统方案的可行性。研究结果表明：该方案能够实现平流层浮空器全天候快速部署。

Modeling and Simulation of Rapid Deployment System for Stratospheric Aerostat

Aiming at the risks and disadvantages such as lots of restrictive conditions of aerostat takeoff, great risk in levitation, a long time of deployment, a new scheme of rapid deployment for the aerostat is presented in this paper. In the scheme, the aerostat is launched by a vehicle to an objective airspace. Then, the rapid deployment is completed through system separation, brake parachute deceleration, inflation in air, and aerostat expansion. The multi-body dynamics model of the brake parachute, aerostat and Inflation mechanism during the process of Inflation and expansion is established through analysis of the system structure and work process. The results show that this scheme can achieve the all-weather rapid deployment of stratosphere aerostat.
