摘要
常规部署的平流层浮空器受放飞条件和时间限制,相比之下,空基投放浮空器系统具有高效和灵活的优势。建立了减速伞和浮空气球的动力学模型,提出了平流层浮空器区域驻留轨迹控制策略,构建了一款空基投放无动力平流层浮空器的动力学仿真平台,并对系统的部署过程和区域驻留过程进行了轨迹仿真分析。仿真结果表明,采用空基投放的快速部署方式,可以在335 s内快速部署平流层浮空器,且当区域驻留控制半径设定为距投放点30 km时,浮空器偏离投放点的最大距离约为40 km,实现了较好的区域驻留控制效果。为平流层浮空器的快速部署与长期区域驻留提供了理论支持和技术参考。
Conventional deployment of stratospheric aerostats is limited by launch conditions and time constraints.In contrast,airborne-deployed systems offer advantages in efficiency and flexibility.This paper establishes the dynamic models for the deceleration parachute and aerostat balloon,proposes a territory-hovering control strategy for stratospheric aerostats,and develops a dynamic simulation platform for airborne-deployed unpowered stratospheric aerostats.The paper also conducts a trajectory simulation analysis of the system s deployment and territory-hovering processes.The simulation results indicate that the airborne-deployed method enables rapid deployment of stratospheric aerostats within 335 seconds.Furthermore,when the territory-hovering control radius is set to 30 km from the deployment point,the maximum deviation of the aerostat from the deployment point is approximately 40 km,demonstrating effective territory-hovering control performance.This paper provides theoretical support and technical reference for the rapid deployment and long-term territory-hovering of stratospheric aerostats.
