目的 介绍一种新概念空投方式，即旋翼式空投系统及包装设计。方法 结合自旋转翼气动力学分析旋翼空投系统工作原理，并根据相关设计准则开展旋翼式空投系统关键件的包装设计研究。结果 自旋转翼气动升力是减缓空投物资下降速度的主要因素，而合成气流的攻角在内侧大而在外侧小，造成旋翼在整个翼面具有不同的功能分区。实验结果证明了旋翼空投系统减速原理的可行性。结论 旋翼空投系统具有成本低、包装快等优势，是一种值得推广的新型空投装备，同时应注重空投系统的包装设计。

The work aims to introduce a new concept airdrop equipment, namely the rotary-blade delivery system and its packaging design. The principle of the delivery system was analyzed based on rotary-wing aerodynamics; and the packaging design of key components was researched. Aerodynamic force on rotary wing was a key factor to slow down the airdrop system. The angle of attack of converged air flow was big inside and small outside. Relative air flow in different sections made different function divisions on the whole rotary wing. The experimental results confirmed the feasibility of this kind of the delivery system. In conclusion, low cost and fast packaging make the rotary-blade delivery system worth promoting. However, it is very important to pay attention to packaging design.
