Embodiment 1

[0039] see figure 1 , an electric vertical take-off and landing aircraft structure, comprising a fuselage part 1, a wing part 2 connected to the left and right sides of the middle and upper part of the fuselage part 1, and a flat tail part 3 connected to the left and right sides of the tail of the fuselage part 1; The ends of the wing parts 2 and the ends of the left and right flat tail parts 3 are all provided with tilting propellers; the middle parts of the left and right wing parts 2 are respectively connected to the nacelle parts 4, and the nacelle parts 4 are provided with foldable propellers. Preferably, four groups of tilting propellers are arranged at the ends of the left and right wing parts 2 and the ends of the left and right flat tail parts 3, that is, four groups of power systems, and two groups of foldable propellers are arranged on the nacelle parts of the left and right wing parts 2, namely Two sets of power systems, six sets of power systems to provide power f...

Embodiment 2

[0053] Embodiment 2 of the present invention provides a structural working method of an electric vertical take-off and landing aircraft, including:

[0054] Initial stage: The aircraft is initially in a multi-rotor state. In the multi-rotor state, the left and right wing tilting nacelles and the left and right horizontal tail tilting nacelles are all rotated to 90° upward, and the foldable propellers on the nacelle parts are unfolded into a four-blade state;

[0055] Flight stage: After passengers board the plane, the six sets of power systems composed of left and right wing components, left and right horizontal tail components and left and right nacelle components provide lift to take off vertically and fly to a safe height;

[0056] Control the left and right wing tilting nacelles, and the left and right horizontal tail tilting nacelles to tilt forward slowly to provide forward flight thrust for the aircraft; the forward flight speed of the aircraft continues to increase unti...

Abstract

The invention relates to the technical field of urban air traffic, and discloses an electric vertical take-off and landing aircraft structure and a working method thereof. The electric vertical take-off and landing aircraft structure comprises a fuselage component, wing components (2) connected to the left side and the right side of the middle-upper portion of the fuselage component and flat tail components connected to the left side and the right side of the tail of the fuselage component, wherein tilting propellers are arranged at the end parts of the left and right wing components and the end parts of the left and right flat tail components; and nacelle components are respectively connected to the middle parts of the left and right wing parts, and foldable propellers are arranged on the nacelle components. The tilting power system has higher take-off and cruise performance, and the operation efficiency of the aircraft is obviously improved by increasing the cruise flight speed; a propeller tilting mechanism is designed, so that the vertical take-off and landing function is met, and course thrust can be provided for cruising; and a pitch changing mechanism is designed to change the pitch of the propeller, so that the propeller works in a high-efficiency interval under two working conditions of low-speed incoming flow during vertical take-off and landing and high-speed incoming flow during a cruising stage, and the endurance performance of the whole machine is improved.

Description

technical field [0001] The invention relates to the technical field of urban air traffic, in particular to a structure of an electric vertical take-off and landing aircraft and a working method thereof. Background technique [0002] With the continuous increase of urban road vehicle density, the daily commuting time of human beings is gradually increasing. The concept of Urban Air Mobility (UAM, Urban Air Mobility) has been put forward by virtue of the favorable condition that the city has low-to-medium airspace that has not yet been fully developed. Electric vertical take-off and landing aircraft has become the most important urban air traffic solution due to its important advantages of being green and less dependent on infrastructure. At present, there are two common layout forms in the industry. One layout is the multi-rotor layout form: this type of aircraft relies on multiple sets of lift rotors to provide the vertical take-off and landing and forward flight power of t...
