Abstract

The invention relates to a tiltrotor aircraft, which comprises a body, a pair of wings positioned on two sides of the body, ailerons positioned on the wings and emages arranged on the tail part of the body. The pair of wings is both provided with an engine; each engine is connected with a propeller; the wings are rotatably connected to the body; the engines are fixed on the wings; and the rear part of each propeller corresponding to the wing is respectively provided with a horizontal tilt wing, a vertical stable wing and a vertical resistance plate. Compared with the prior art, the tiltrotor aircraft is simple, safe and reliable to realize without depending on a complex mechanical and electronic system; the engines are fixedly connected relatively to the wings, the wings can rotate relatively to the body, the wings and the engines tilt together in the takeoff and landing process, the rotor surface is always vertical to the wing surface under any working condition, and the wing surface cannot obstruct airflow from the propellers, so that the pneumatic efficiency of the engine is improved; and the engines are positioned at the root of the wings so as to effectively reduce the requirement on the strength of the wings and facilitate reducing weight.

Description

technical field [0001] The invention relates to aircraft, in particular to a tilt rotor aircraft. Background technique [0002] Tilting rotor aircraft is a new type of aircraft that combines the advantages of fixed-wing aircraft and helicopters. Some people vividly call it a "hybrid" in the air. Compared with helicopters, tiltrotors have longer range and higher speeds. Compared with fixed-wing aircraft, tilt-rotor aircraft can take off and land vertically, and require less space. [0003] The U.S. military aircraft V-22 "Osprey" is the tilt rotor aircraft that is actually put into use. The fuselage and wings of the V-22 are basically similar to ordinary fixed-wing aircraft. The difference is that the propeller engines located at both ends of the wing can rotate up and down, and the angle of attack of the rotor is controllable, which can realize the functions of vertical take-off and landing and fixed-wing cruise. Its novel concept, excellent performance and wide applicati...
