Embodiment Construction

[0031] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0032] refer to Figure 1-3 , the aircraft with tiltable wings has a fuselage 10, and the cockpit is located under the windshield 11. The tail of the fuselage 10 is provided with a vertical empennage 12, and a rudder 14 is also arranged on the vertical empennage 12. A horizontal stabilizer 16 is also installed on the empennage 12 , and two elevators 18 are provided on the horizontal stabilizer 16 .

[0033]Three inclined wings are mounted on the fuselage 10 : a front wing 20 , a middle wing 22 and a rear wing 24 . Wings 20, 22 and 24 (which are also referred to as main wings) are respectively mounted on and are rotatable about rotational tilt axes 20D, 22D and 24D. Tilt axes 20D, 22D and 24D are transverse to the longitudinal axis ...

Abstract

A tilt wing aircraft is provided with multiple wings arrayed at intervals. The wings are installed on a fuselage and pivot along with corresponding tilt shafts between the taking off and landing position and the cruise position, and the multiple tilt shafts are parallel. At the cruise position, the interval between every two adjacent wings is less than the width, measured on the fuselage, of any one of the multiple wings. Multiple power units are installed on one or more wings and rotate along with the one wing or more wings between the vertical propulsion position and the forward propulsion position. When the power units are located at the vertical propulsion position, the wings rotate to the vertical position, so that the power units can generate downward airflow through the wings, to push the fuselage. When the angles of attack of revolving wings and the power units are decreased, the fuselage can move forward.

Description

technical field [0001] The invention relates to a vertical take-off and landing aircraft, in particular to an aircraft whose wings can be inclined relative to the fuselage. Background technique [0002] Conventional fixed-wing aircraft wings have rounded leading edges and pointed trailing edges. This aerodynamically shaped wing creates lift when air flows quickly over it. In order for the wings to create enough lift to sustain flight, this type of aircraft needs to traverse a fairly long runway to gain sufficient speed. When landing, the aircraft has a very fast speed when it touches the ground. After it has to travel a considerable deceleration distance, its speed can reach the standard for allowing turning or stopping, so the aircraft also needs a long runway for landing. [0003] Long runways are also not feasible in many environments, either because of terrain, or because of economic considerations. Understandably, there are many advantages to an aircraft that can tak...
