Description

technical field [0001] The invention relates to the field of flying equipment, in particular to an aircraft. Background technique [0002] There are many types of aircraft, such as ground-effect aircraft, tilt-rotor aircraft, etc., and different types of aircraft have different characteristics. [0003] For example, a ground-effect aircraft is an aircraft that uses the wing-ground effect to fly. The ground effect aircraft has the following advantages: (1) When the aircraft flies close to the water surface, ice surface or flat land surface (collectively referred to as the support surface), a high-pressure air cushion is formed between the wings of the aircraft and the support surface, which can greatly increase the lift and drag of the aircraft Ratio (increased lift coefficient, reduced induced drag), so that the aircraft has higher aerodynamic efficiency and greater load capacity; (2) Ground-effect aircraft can fly at very low altitudes, so it also has higher flight safety ...

AI Technical Summary

Problems solved by technology

At present, the most representative tiltrotor aircraft in the world is the V22 "Osprey". Its endurance can reach nearly 10 times that of ordinary helicopters, but its rotor system overload capacity is only 1.4, far less than 3.5 of helicopters. Therefore, the maneuverability Poor; in addition, the V22's engine and rotor tilt system components are mounted on the wingtips, requiring the wing to pay a huge structural weight penalty

Miniature / light tilt-rotor aircraft with four rotors have begun to appear in China, and the flight stability has been improved in theory, but it is only a mechanical combination of multi-rotor aircraft and fixed-wing aircraft, requiring a separate power equipment installation structure

Moreover, in the fixed-wing cruising state, if the four power units work at the same time, a pitch-variable structure is required to ensure the high efficiency of the four power plants. A power plant stops working and becomes a "dead weight", so the endurance is low
