Telescopic wing of aircraft

Abstract

The invention relates to a telescopic wing of an aircraft, in particular to a telescopic wing on a small aircraft which can lift in complex regions of high mountains, gorges and the like. The telescopic wing comprises a wing body which is vertically arranged. A wing cover is fixed on the rear side of the middle of the gravity center of the wing body, outlets are formed in both the left end and the right end of the wing cover, a worm gear case is arranged at the center of an inner cavity of the wing cover, and telescopic wing bodies are arranged on both the left side and the right side of the worm gear case and in sliding fit with the outlets. Rectangular notches are formed in the lower sides of the outer ends of the two telescopic wings, wing blocks are arranged in both the rectangular notches, and a worm and gear mechanism is arranged in the worm gear case. Through the worm and gear mechanism and the like, the telescopic function of the telescopic wing can be achieved, and the angles of the wing blocks can be adjusted. The aircraft with the telescopic wing is small in oil consumption, high in flight speed, and long in voyages.

Description

technical field [0001] The invention relates to an aircraft wing. Specifically, it is a retractable wing on a small aircraft that can take off and land in complex areas such as mountains and canyons. Background technique [0002] The China No. patent specification discloses a kind of small aircraft that can take off and land in narrow and complicated terrains such as high mountains and canyons. This small aircraft contains a main frame, two ducts, a lateral swing wing, a longitudinal swing wing, a direction control mechanism, an engine and a support, and the axes of the two ducts are parallel. There is a shaft seat in the center of the inner cavity of the duct, and supports are evenly distributed between the shaft seat and the inner wall of the duct. A paddle shaft is arranged in the shaft seat and the two are rotatably matched. A propeller is arranged at the upper end of the paddle shaft, and the outer walls of the two ducts are connected by a connecting frame. The main...

Problems solved by technology

However, since the take-off of this kind of aircraft depends entirely on the lift generated by the high-speed rotation of the propellers in the two ducts, it consumes a lot of fuel, and most of the power consumption is used to lift the weight of the aircraft. The power consumption of the forward flight is small, which makes the aircraft consume a lot of fuel, fly slowly, and have a short range
