摘要： An ultralight coaxial dual rotor helicopter having a substantially L shaped frame. Attached to the back of the frame is a vertical shaft engine, and a pair of yaw paddles for controlling yaw of the craft. The drive shaft connects to a belt drive at the top of the frame, which transmits the engine power to a transmission and coaxial drive gear for driving the rotors. Crank actuators are provided for tilting the rotor axis to control the pitch and roll of the craft. A pilot seat and ballast tank are attached to the front of the frame. The ballast tank may be filled with a volume of water to balance the craft for the weight of the pilot. The fuel tank is located behind the pilot seat on the centerline of the helicopter, such that as fuel is used and the weight of fuel in the tank changes, the balance of the craft will not be affected.
摘要翻译： 一种具有大致L形框架的超轻同轴双转子直升机。 连接到车架背面的是垂直轴发动机和用于控制飞行器偏航的一对偏转桨。 驱动轴连接到框架顶部的皮带传动装置，其将发动机功率传递到用于驱动转子的变速器和同轴驱动齿轮。 提供曲柄致动器用于倾斜转子轴线以控制工艺的俯仰和滚动。 飞行员座椅和压载舱附在机架的前部。 压载舱可以装满一定量的水以平衡飞行员重量的飞行器。 燃油箱位于直升机中心线上的驾驶员座椅的后面，使得当使用燃料并且罐中的燃料重量改变时，工艺的平衡将不受影响。
