Retractable angle-adjustable helicopter stub wing

Abstract

The invention discloses a retractable angle-adjustable helicopter stub wing. A fuselage, an empennage and a stub wing are included, an undercarriage is mounted under the fuselage; a main rotor is installed at the top of the fuselage, the empennage is arranged at the tail end of the fuselage, the stub wing is arranged on the outer side of the middle of the fuselage, a storage cavity located in thefuselage is formed in the outer side of the stub wing, a hinge is installed at the tail end of the stub wing, a driver is installed in the storage cavity, and a center control box is arranged on the outer side of the driver. According to retractable angle-adjustable helicopter stub wing, the defect that the stub wing of a retractable helicopter cannot be unfolded in high-speed movement is overcome; the defect that the included angle between a stub wing and a fuselage of a retractable helicopter is fixed and cannot be adjusted is overcome, the stub wing can be adjusted when the helicopter fliesforwards at a high speed, flies in a circling maneuvering mode, hovers, takes off and lands vertically, flies at a low speed and slides down in an autoroatation mode, and power can be used to the maximum extent.

Description

technical field [0001] The invention relates to the field of overall design of the helicopter, which is used to increase the flight speed of the helicopter, or to reduce the required power of the helicopter when flying forward, and specifically relates to a retractable and adjustable angle helicopter short wing. Background technique [0002] Helicopters have features that fixed-wing aircraft do not have, such as: efficient hovering, low-speed forward flight, etc., and have a wide range of practical applications in both military and civilian fields. However, with the advancement of science and technology and the rapid development of the times, the demand for increasing the flying speed of the helicopter, or reducing the power required for the forward flight of the helicopter, and reducing the fuel consumption of the helicopter are becoming more and more urgent. [0003] Armed helicopters usually use short wing parts to hang the weapons outside, which will generate lift when f...

AI Technical Summary

Problems solved by technology

[0007] In order to improve the flight efficiency of the helicopter when it is flying forward, the present invention proposes a retractable and adjustable angle helicopter short wing solution for the short wing part of the helicopter, which solves the disadvantage that the retractable short wing of the helicopter cannot be deployed in high-speed motion , which solves the disadvantages of fixed and non-adjustable angles between the short wing and the fuselage of the retractable helicopter
