Variable adjustment backswept wing mechanism of fixed-wing aircraft

Abstract

The invention discloses a variable adjustment backswept wing mechanism of a fixed-wing aircraft. The variable adjustment backswept wing mechanism comprises a wing, a wing pull sheet, a pull sheet sliding frame, a wing pull rod, a pull rod fixing seat and a guide seat, wherein an end part of the outer side of the wing pull sheet is fixedly connected with the wing; an end part of the inner side of the wing pull sheet is hinged with a pull sheet sliding block and the wing pull rod; the pull sheet sliding frame is fixed on an aircraft body; a pull sheet sliding rail slot which is in sliding fit with the pull sheet sliding block is formed in the pull sheet sliding frame; the other end of the wing pull rod is hinged with the pull rod fixing seat; a screw rod is mounted in the guide seat; the pull rod fixing seat is mounted on the screw rod in a sleeving manner and is connected with the guide seat in a sliding manner; a driving end of the screw rod is connected with a driving motor through atransmission mechanism. The variable adjustment backswept wing mechanism of the fixed-wing aircraft is reasonable in structural design; a backswept wing can reasonably change according to a flying requirement, so that a better flying speed can be provided for flying of the aircraft.

Description

technical field [0001] The invention relates to the field of swept wing structure of unmanned aircraft, in particular to a variable adjustable swept wing mechanism of a fixed wing aircraft. Background technique [0002] Fixed-wing aircraft, referred to as fixed-wing aircraft, is often referred to simply as an aircraft. It refers to an aircraft that is heavier than air and flies in the atmosphere with the forward thrust or pull generated by the power plant and the lift generated by the fixed wings of the fuselage. It is a type of fixed-wing aircraft, and the most common one, the other type of fixed-wing aircraft is the glider. Aircraft can be divided into jet aircraft and propeller aircraft according to the type of engine they use. In recent years, the field of unmanned aerial vehicles has developed rapidly, among which, the frequency of use of fixed-wing unmanned aerial vehicles is also increasing. [0003] In fixed-wing unmanned aerial vehicles, the wing is an extremely i...

AI Technical Summary

Problems solved by technology

Therefore, the wing plays an important role. However, most of the current aircraft swept wings are fixed structures. In order to overcome the problem that the larger the area of ​​the wing, the greater the lift and the greater the resistance, our company developed this variable adjustable swept wing mechanism. , which allows the drone to provide better flight speed when flying
