Problems solved by technology

In addition, there is an obvious disadvantage of this folding method. After the wings are folded at the airport, the internal mechanism and system equipment on the folding surface will be exposed. Obviously, this is not conducive to preventing the aircraft from being exposed to the sun when it is parked at various airports. Invasion of external environmental factors such as sand, dust, rain and snow

Abstract

The invention relates to a pull rod type aircraft folding wingtip and an operation method thereof. The wingtip comprises a fixed end, a folding end, a connecting part and a power conversion part. Each of the fixed end and the folding end comprises an upper wing surface and a lower wing surface; the connecting part is connected with the fixed end and the folding end; the folding end is driven by the power conversion component to rotate, the folding end can rotate around the connecting component within the range of 0-90 degrees, wing tip folding is achieved, and an aircraft meets the requirements of airport runways, taxiways and parking places for the width of the aircraft.

Description

technical field [0001] The invention relates to the field of aircraft body structure design, in particular to a rod-type aircraft folding wingtip and an operation method thereof. Background technique [0002] Improving the lift-to-drag ratio of an aircraft by using wings with a large aspect ratio has become a major consideration for reducing fuel consumption in the design of modern wide-body airliners. In order to overcome the resulting adaptability of the aircraft to the airport, that is, the large wingspan of the aircraft may exceed the requirements for the width of the aircraft on the airport runway, taxiway and parking area. In recent years, the folding wing design has begun to be used on large wide-body passenger aircraft. It has received more and more attention, especially the successful application of Boeing's foldable wingtips on the B777X has shown a good market prospect for the further development of foldable wing technology in the future. Although the application...
