Abstract

The invention provides a retractable helicopter short wing and relates to the field of helicopter structure design. The short wing comprises a first short wing box section (1), which includes a leading edge telescopic channel (11), a main load-bearing telescopic channel (12) and a trailing edge telescopic channel (13); the second short wing box section (2) , which includes a leading-edge telescopic section (21) that can expand and contract from the leading-edge telescopic channel (11), a main load-bearing telescopic section (22) that can expand and contract from the main-bearing telescopic channel (12), and a self-rear-edge telescopic channel (13) The inner telescopic rear edge telescopic section (23); and the three-axis electric cylinder (3), the three synchronously driven output shafts are respectively connected to the front edge telescopic section (21), the main force-bearing telescopic section (22) and the rear edge telescopic section (22). Paragraph (23). When the helicopter is flying forward, extending the short wings can effectively increase the lift of the helicopter and enhance the plateau performance of the helicopter.

Description

technical field [0001] The invention relates to the field of helicopter structure design, in particular to a retractable short helicopter wing. Background technique [0002] Helicopter short wing refers to the structure used for mounting in the middle or middle front of the helicopter body. It can generally be used to hang auxiliary fuel tanks, rockets, missiles, etc., and can also unload the rotor to provide part of the lift for the helicopter. The design of existing short wing of helicopter is that short wing box section is connected on the body, is fixed structure, and wingspan is shorter. [0003] The short wing span of the existing helicopter is relatively short, and the lift provided for the helicopter is limited. If the short wing is designed too long, on the one hand, the downwash flow will generate downward pressure on the upper surface of the short wing during hovering, which will have an adverse effect on the lift system of the helicopter; on the other hand, it w...
