Three-flight-mode electric universal aircraft capable of vertically taking off and landing

Abstract

The invention discloses a three-flight-mode electric universal aircraft capable of vertically taking off and landing, and belongs to the field of aircrafts. The aircraft comprises a fuselage, wings, a power system, an empennage, an undercarriage, a cabin, a fairing, a first rotating shaft, a second rotating shaft, a wing support and a switching mechanism; the power system adopts propellers for propelling, blades of the propellers are unfolded to rotate around a shaft in a working state, and the blades are retracted to the fairing in a non-working state; the wings on the two sides are connected into a whole through the switching mechanism and rotationally connected through the first rotating shaft, so that the wings can rotate around the axial direction of the first rotating shaft relative to the switching mechanism, and switching between the vertical take-off and landing posture and the fixed wing posture is achieved. The switching mechanism is fixed right above the fuselage through the wing support, and the wing support is rotationally connected with the switching mechanism through the second rotating shaft, so that the switching mechanism drives the wings on the two sides to rotate around the second rotating shaft, and switching between the fixed wing posture and the rotor posture is achieved. The aircraft has the advantages of three different flight modes, and can overcome the defects caused by a single flight mode.

Description

technical field [0001] The invention belongs to the field of aircraft, in particular to an electric universal aircraft capable of vertical take-off and landing with three flight modes. Background technique [0002] In recent years, China's general aviation aircraft has developed rapidly, with an average annual growth rate of more than 10% of the total number of flights. The scale of the industry is expanding, the application fields are expanding, the types of flight are increasing, and the demand for flight is becoming stronger. Promoting the development of general aviation is of great significance to building a civil aviation power. General aviation aircraft has many advantages such as easy operation and low requirements for take-off and landing sites. [0003] Electric aircraft use electric propulsion instead of internal combustion engine power, thereby gaining many advantages and unique qualities. The most prominent advantages are energy saving and environmental protect...

Problems solved by technology

However, when the V-22 engine stops in the air, its propeller is driven by the engine shaft and cannot spin and land.

[0006] General-purpose aircraft has good application prospects due to its many advantages such as easy operation and strong flexibility. However, it needs to run during take-off and landing, and is highly dependent on the flight site and environment; Time is short, reliability is low, this is the technical problem to be solved by the present invention
