- 用等离子体电风产生推力，无机械部件
- 双自由度舵机实现稳定悬停与全飞行包线操控
- 适合对噪音敏感的室内或近太空场景
本研究提出一种新型等离子体驱动超静音飞艇（PUB），采用氦气浮力平台实现长续航，通过四层环形非对称电容器产生离子风推力。模块化推进单元支持任务定制配置，双自由度（DOF）头部实现推力矢量控制。闭环滑移控制策略保障飞行稳定性。飞行实验验证了起飞、爬升、悬停、下降和平稳着陆的全包线能力，证实了等离子体矢量推进的可行性、矢量控制的有效性及控制系统的稳定性。由于声学特征低、结构简单且机动性强，PUB适用于对噪声敏感、封闭空间及近太空环境的应用。
原文摘要 · Abstract (English)
This study presents the design and control of a Plasma-propelled Ultra-silence Blimp (PUB), a novel aerial robot employing plasma vector propulsion for ultra-quiet flight without mechanical propellers. The system utilizes a helium-lift platform for extended endurance and a four-layer ring asymmetric capacitor to generate ionic wind thrust. The modular propulsion units allow flexible configuration to meet mission-specific requirements, while a two-degree-of-freedom (DOF) head enables thrust vector control. A closed-loop slip control scheme is implemented for stable maneuvering. Flight experiments demonstrate full-envelope capability, including take-off, climb, hover, descent, and smooth landing, confirming the feasibility of plasma vector propulsion, the effectiveness of DOF vector control, and the stability of the control system. Owing to its low acoustic signature, structural simplicity, and high maneuverability, PUB is well suited for noise-sensitive, enclosed, and near-space applications.
