    • A propeller related vehicle in accordance with one embodiment of the present invention is described as a helicopter having an airframe housing a motor mechanism for powering a main propeller attached to a main drive shaft that extends vertically through the airframe and for powering a tail rotor. The helicopter further includes a horizontal stabilizing mechanism attached between the main propeller and the main drive shaft, which permits the main propeller to freely pivot about the main drive shaft independently from the airframe. As such when the main propeller is rotating and the main propeller begins to pitch, the rotating main propeller has a centrifugal force created by the rotation thereof and will tend to pivot about the horizontal stabilizing mechanism in a manner that offsets the pitch such that the helicopter remains in a substantially horizontal position. In addition various main propeller configurations may be employed that provide additional self-stabilization.
    • 根据本发明的一个实施例的螺旋桨相关车辆被描述为具有机身的直升机,其具有容纳用于为主驱动轴连接的主螺旋桨供电的马达机构,所述主螺旋桨垂直延伸穿过机身并为尾部转子供电。 直升机还包括安装在主推进器和主驱动轴之间的水平稳定机构,其允许主螺旋桨独立于机身围绕主驱动轴自由枢转。 因此,当主螺旋桨旋转并且主螺旋桨开始俯仰时,旋转的主螺旋桨具有由其旋转产生的离心力,并且将趋向于以水平稳定机构的方式枢转,以偏移俯仰,使得直升机 保持在基本上水平的位置。 此外,可以采用提供额外的自稳定性的各种主要的螺旋桨结构。
