The invention provides two types of manned multi-propeller aircrafts and two types of unmanned remote control multi-propeller aircrafts, outer edge ring wing blade type propellers are used for generating lift force and flight power, outer edge flat ring wings are used for cutting and adapting to windward rapid laminar flow or crosswind laminar flow, and after the windward or crosswind laminar flow is cut and drained through the outer edge flat ring wings, direct airflow impact of windward or crosswind laminar flow on the blades on the inner sides of the ring wings is avoided, shock wave tremor of the tips of the blades in the ring is avoided, and the problems of large wind resistance, unstable flight or hovering wind blowing yawing caused by the reasons are avoided or relieved; in addition, by adopting the outer edge ring wing blade type propellers, fingers or flying obstacles can be prevented from being cut by blades on the inner sides of the ring wings, hooking of obstacles such as branches and cables to the blades during flying is reduced, personal safety is protected, and flying safety is further improved. Compared with a common blade type propeller unmanned aerial vehicle needing to be additionally provided with a blade protection ring, the outer edge ring wing blade type propellers still have safety if the blade protection ring is not installed after the outer edge ring wing blade type propellers are adopted.
本发明提供两种有人驾驶和两种无人遥控的多旋桨飞行器,其采用外缘环翼叶式螺旋桨来产生升力和飞行动力,利用外缘扁平环翼来切割和适应迎风快速层流或横风层流,使迎风或横风层流经外缘扁平环翼切割引流后,避免迎风或横风层流对环翼内侧桨叶产生直接气流冲击,避免环内桨叶翼尖产生激波震颤,避免或减轻这些原因带来的风阻较大、飞行不稳或悬停风吹偏航问题;此外,采用外缘环翼叶式螺旋桨可避免环翼内侧桨叶砍击切割手指或飞行障碍物,减少飞行时树枝线缆等障碍物对桨叶的钩挂,有利于保护人身安全和进一步提高飞行安全性;且相比需要加装桨叶防护圈的普通叶式螺旋桨无人机,采用外缘环翼叶式螺旋桨后如果不安装桨叶防护圈也仍具备安全性。
