Electric aircraft with a plurality of ducted propellers, telescopic wing and telescopic aircraft body

Abstract

The invention provides an electric aircraft with a plurality of ducted propellers, telescopic wing and telescopic aircraft body, which belongs to the field of air materials. According to the invention, the wing comprises a plurality of embedded wing sections; during taking off, landing and parking, the tail parts of the wing and the aircraft body can retract; after liftoff, the tail parts of the wing and the aircraft body are unfolded; and the plurality of ducted propellers capable of tilting are symmetrically distributed in front of and behind the wing and on left and right sides of the aircraft body. Through adoption of the layout, the aircraft can vertically take off and land and can also rapidly fly in a flat way; the floor area is reduced during vertical take off and landing and parking; and during flat flight, the plurality of ducted propellers can tilt for 90 degrees so that the flying speed and airborne period are increased. The takeoff and landing process is safe and reliable and the flight attitude is stable. The invention can be made into manned aircrafts and can be also made into unmanned aerial vehicles.

Description

technical field [0001] The invention relates to an electric aircraft composed of wings, a horizontal empennage, a vertical empennage and a plurality of ducted propellers, which belongs to the field of aviation equipment. Background technique [0002] At present, known helicopters or multi-rotor UAVs all rely on rotary wings to take off vertically, hover and fly horizontally. Due to the existence of the rotors, when taking off and landing in a small space, they are harmful to the surrounding pedestrians or themselves. Certain danger. Chinese patent literature application number: 200420063679.0, name: tandem double duct four nozzle single-person aircraft and application number: 200920053565.0, title: double duct vertical take-off and landing flying car etc. also provide some duct aircraft However, the former is a fixed wing, which occupies a large area when taking off and parking vertically; the latter has no wings, consumes a lot of power, has a short time to stay in the air,...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages of large floor space, energy consumption, and poor safety in the prior art, the present invention provides an electric aircraft solution with multiple tilting ducted propellers, retractable wings and fuselage, so that the aircraft can fly vertically Small footprint when landing, energy saving when flying horizontally, long air time, low resistance when flying at high speed, stable flight attitude, and safe and reliable takeoff and landing
