Example Embodiment

[0038] Example one

[0039] See figure 1 , An electric vertical start-off aircraft structure includes a body member 1, a wing member 2 coupled to the upper left and right side of the body member 1, and is connected to a flat end member 3 on the left and right sides of the fuselage member 1; The wing member 2 ends and left and right tail members 3 are provided with a tilted propeller; the short cabin member 4 is respectively connected in the middle of the left and right wing member 2, and a foldable propeller is provided on the short cabin member 4. Preferably, four sets of tilted propellers are disposed at the end portion of the left and right wing member 2 and the left and right tail member 3, that is, a four sets of power systems, and two sets of foldable propellers are disposed on the short cabin member of the left and right wing member 2, that is, Two sets of power systems, multifocal-wide state six sets of power systems provide power to the whole machine to effectively preven...

Example Embodiment

[0052] Example 2

[0053] The second embodiment of the present invention provides an electric vertical starting aircraft structure, including:

[0054] Initial phase: The aircraft is initially in the multi-rotation state, the left and right wing of the left and right wings, the left and right tail tuning is rotated to 90 °, the foldable propeller on the short cabin is deployed as a four-leaf axle.

[0055] Flight stage: After the passenger is closed, the left and right wing components, the left and right tail parts, and the left and right short-tail components, the six-set power system consisting of the left and right, and the left and right power systems provide lift vertical takeoff, flying to the safety height;

[0056] Control the left and right wings, the left and right tail tuning the short-term slow forward, providing the front flying force for the aircraft; the flying speed of the aircraft is increasing until a specific speed, the foldable propeller on the left and right s...

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...
