The invention provides a combined type high-speed helicopter based on a conventional rotor wing structure. The combined type high-speed helicopter comprises a helicopter body, a rotor wing system, wings located on the two sides of the helicopter body, propeller systems installed on the wings, a horizontal tail and double vertical tails, wherein the horizontal tail and the double vertical tails are installed at the tail end of the helicopter body. When the helicopter is in a hovering state and a low-speed forward flying state, the rotating speed of rotors in the rotor systems is A, the propeller systems are used for balancing reaction torque generated by the rotor systems, and when the helicopter is in the low-speed forward flying state, the propeller systems provide part of forward flying power; when the helicopter is in a high-speed forward flying state, the rotating speed of the rotor wings in the rotor wing system is B, the propeller system is used for providing all forward flying power, and A is larger than B. The helicopter has the advantages of a common helicopter and a fixed-wing aircraft, the vertical take-off and landing and hovering characteristics of the helicopter are reserved, the flight speed of the helicopter is increased to a certain degree, and the application field of the helicopter is widened.
本发明提供一种基于常规旋翼构型的复合式高速直升机,包括机身、旋翼系统、位于所述机身两侧的机翼、安装在所述机翼上的螺旋桨系统、安装在所述机身尾端的平尾和双垂尾;所述直升机在悬停和低速前飞状态时,所述旋翼系统中旋翼的转速为A,所述螺旋桨系统用于平衡所述旋翼系统产生的反扭矩,在低速前飞状态时,所述螺旋桨系统提供部分前飞动力;所述直升机在高速前飞状态时,所述旋翼系统中旋翼的转速为B,而所述螺旋桨系统用于提供全部前飞动力,其中A大于B。该直升机兼具普通直升机和固定翼飞机的优点,既保留了直升机垂直起降、悬停的特性,又一定程度的提高了直升机的飞行速度,拓宽了直升机的应用领域。
