Abstract: This disclosure is directed to a single blade propeller and systems, devices, and techniques pertaining to assisting in critical stages of flight (e.g., takeoff, landing, emergency situations, etc.) in vertical takeoff and landing (VTOL) aircraft. The single blade propeller may be incorporated into fixed and rotary wing VTOL aircraft as part of a first propulsion system. The first propulsion system may include one or more single blade propellers driven by electric motors, combustion engines, and/or hybrid engines. Each of the single blade propellers may include a lift-producing blade and a counterweight opposite the lift-producing blade. As each of the single blade propellers spins, it may produce lift in a direction approximately perpendicular to the horizon to effect vertical flight.

Abstract translation: 本公开涉及一种涉及在垂直起飞和着陆（VTOL）飞机中辅助关键飞行阶段（例如起飞，着陆，紧急情况等）的单个桨叶螺旋桨和系统，装置和技术。 作为第一推进系统的一部分，单桨螺旋桨可以并入固定和旋转翼型垂直起降飞机中。 第一推进系统可以包括由电动机，燃烧发动机和/或混合发动机驱动的一个或多个单个叶片螺旋桨。 单个叶片螺旋桨中的每一个可以包括提升产生叶片和与提升产生叶片相对的配重。 当每个单刀片螺旋桨旋转时，它可能在大致垂直于地平线的方向上产生升力以实现垂直飞行。
