Variable-wing type aircraft with controllable circular rector

Abstract

The invention discloses a Variable-wing type aircraft with a controllable circular rector, comprising a propeller, a main engine, an aircraft body, wings, a vertical tail and a horizontal tail, wherein an impeller power machine is arranged at the connecting part of the middle part of the aircraft body and the wings; each wing is internally provided with an impeller; the rotating shafts of the impellers are fixed on an end plate of the wings through bearings; an output shaft of the impeller power machine is connected with the rotating shafts of the impellers; the parts of the wings, above or below the impellers, are open; the front edge and the rear edge of each wing are internally provided with an upper movable arc-shaped cover plate and a lower movable arc-shaped cover plate which are used for covering the upper surface and the lower surface of the corresponding impeller; and the upper arc-shaped cover plate and the lower arc-shaped cover plate are connected with control motors through guide rails, worms and reducers. According to the controllable-circular-rector variable-wing type aircraft, the impellers rotate to accelerate air flow so as to generate circular rector, so that the wings increase the extra lift, and the aircraft can generate enough lift to fly when the speed of relative movement of the aircraft and air is very low; consequently, the taking off and landing safety of the aircraft is greatly improved, and the aircraft can generate enough lifting force to realize the short-distance taking off and landing.

Description

technical field [0001] The invention belongs to a circulation controllable variable-wing aircraft. Background technique [0002] Small and medium-sized manned aircraft (or unmanned aerial vehicles) have been widely used and developed rapidly in the civilian field in recent years because of their lightness, smallness and flexibility, and the need for parking and landing at large airports. In particular, general aviation has a great development trend in recent years. Various aircrafts have been designed and manufactured one after another, which represent an important development direction of current aviation technology. Among various small manned aircraft schemes such as light aircraft, ultra-light aircraft, and small helicopters, the aircraft that does not need to take off and land at the airport will have obvious advantages. But existing small aircraft also has many unsatisfactory parts and shortcomings in use and flight, such as large take-off distance and short flight ran...
