The invention discloses a novel helicopter stub wing and a helicopter, which relate to the technical field of helicopters. The stub wing comprises a mounting frame, stub wing bodies are fixedly mounted on the two opposite side faces of the mounting frame, servo motors are fixedly mounted on the inner bottom faces of the stub wing bodies, the output ends of the servo motors are rotationally connected with connecting rods, one ends of the connecting rods are fixedly connected with driving gears, and mounting plates are fixedly connected to the inner top faces of the stub wing bodies; shaft sleeves are fixedly connected to the two opposite side faces of the mounting plate, and rotating shafts are rotationally connected into the shaft sleeves. A servo motor is arranged, the servo motor rotates to drive a connecting rod, a driving gear, a driven gear, a rotating shaft and a lead screw to rotate, and the lead screw is in threaded connection with a thread sleeve, so that the thread sleeve can transversely move on the lead screw, finally, a top plate and a lengthened wing can be driven to move, and the lengthened wing is lengthened; during maneuvering flight, the lift force can be increased, the load of the rotor blades is reduced, and the maximum flight overload can be improved.

    本发明公开了一种新型直升机短翼及直升机,涉及直升机技术领域。本发明包括安装架,安装架相对两侧面均固定安装有短翼本体,短翼本体内部底面固定安装有伺服电机,伺服电机输出端转动连接有连接杆,连接杆一端固定连接有主动齿轮,短翼本体内部顶面固定连接有安装板,安装板相对两侧面均固定连接有轴套,轴套内转动连接有转动轴。本发明通过设置设置伺服电机,伺服电机转动带动连接杆、主动齿轮、从动齿轮、转动轴和丝杆转动,配合丝杆与螺套螺纹连接的设置,进而可以使螺套在丝杆上横向移动,最终可以带动顶板和加长翼移动,使加长翼伸长,在机动飞行时可以增加升力,降低旋翼桨叶的载荷,可以提高最大飞行过载。
