Abstract

The invention relates to a cassette hanging fixed wing aircraft. The cassette hanging fixed wing aircraft adopts cassette wing layout and all-electric drive, thus being able to improve the forward flight cruising efficiency and the flight speed of the aircraft, and the symmetrical structure of the cassette hanging fixed wing aircraft can ensure the stability of the aircraft during the tilting transition phase, and the high lift efficiency can reduce reduction of the altitude of the aircraft during the tilting transition period, thus guaranteeing safety of the aircraft. The cassette hanging fixed wing aircraft adopts a combination design of an undercarriage and a vertical fin, and the undercarriage and the vertical fin structure are shared, thus reducing the quality of the aircraft and improving the aerodynamic efficiency of the vertical fin of the aircraft. The cassette hanging fixed wing aircraft adopts an arch-like structure design, and the arch structure has good structural strengthand rigidity, thus improving the structural strength of the aircraft, and ensuring the structural safety of the aircraft. The cassette hanging fixed wing aircraft adopts a combined power device witha tilting rotor and a ducted fan, so that the aircraft has both vertical take-off and forward flight cruising performance, and the aircraft efficiency is improved. The cassette hanging fixed wing aircraft has high structural strength, high front flight cruising efficiency, high flight speed, longer voyage, long flight time, high maneuverability, high safety and high stability.

Description

technical field [0001] The invention relates to the field of aviation aircraft design, in particular to an aircraft that combines a tilting rotor and a box-type fixed wing, and has both vertical take-off and landing and forward-flying cruise performances. Background technique [0002] With the design and use of aircraft such as V247 and V22, tilt-rotor aircraft has gradually become a research hotspot at home and abroad. It has both vertical take-off and landing and forward flight cruise performance, and is of great significance in the military and civilian fields. Tilt rotor aircraft generally have three flight modes, namely vertical take-off and landing mode, tilt transition mode and forward flight cruise mode. When the rotor rotation plane is parallel to the plane of the aircraft body, the aircraft enters the vertical take-off and landing mode; the process of tilting the rotor rotation plane of the tilt rotor from parallel to the plane of the aircraft body to perpendicula...
