Novel helicopter stub wing and helicopter

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of helicopters, in particular to a novel helicopter short wing and a helicopter. Background technique [0002] Helicopters have features that fixed-wing aircraft do not have, such as: high-efficiency hovering, low-speed forward flight, etc., and have a wide range of practical applications in military and civilian fields. Helicopters usually use short wing parts to hang weapons, which will produce Lift is unloaded by the rotor, especially during maneuvering flight, it will increase the maximum flight overload of the helicopter. When the short wings are arranged on the fuselage, the longitudinal position of the aerodynamic center should be as far behind the center of gravity of the whole aircraft as possible, so that the short wings can play a role of stability. The role of the surface to increase the longitudinal static stability of the whole machine. [0003] Most of the existing short wings of helicopters ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of helicopter short wing and helicopter, which solves the problem that most of the existing helicopter short wings use fixed short wings, which may cause reduced lift during flight, increase the load on the rotor blades, and reduce the maximum Flying overloads made it impossible to fit more external fuel tanks or weapons under the short wings etc.
