Layout and control method of a distributed power tilt-wing aircraft

Abstract

The invention discloses a layout and control method of a distributed power tilting wing aircraft. The canard layout aircraft is selected, and a plurality of engines are installed inside the front canard and the main wing of the wing to realize the distributed power; before the vertical take-off state The front canard and the main wing of the wing are tilted to be vertical, and the eight engines generate pulling force to lift the body off the ground, and at the same time, the differential work corrects the attitude of the body; Throttle dynamic adjustment; when the forward flight speed is sufficient to make the lift generated by the front canard and the main wing of the wing offset the gravity, the front canard and the main wing of the wing completely turn to the level, enter the high-speed level flight state, and realize hanging and hovering to The conversion of level flight; the conversion process of level flight, hovering and landing is exactly the opposite. The power system of the present invention is simple to set up, and a locking mechanism is provided; the control of the present invention is direct and reliable, and the tilting mechanism and attitude control are separated to avoid the failure of multiple functions caused by one system failure.

Description

technical field [0001] The present invention relates to a layout and control method of a distributed power tilting wing aircraft, and relates to a layout scheme of a vertical take-off and landing aircraft based on tilting wing technology and its modes of vertical take-off and landing, hovering, and level flight. and the control method for switching between modes. It belongs to the field of aviation technology. Background technique [0002] In recent years, vertical take-off and landing aircraft is very popular in both military and civilian fields. After the U.S. wars against Iraq and Afghanistan ended, the U.S. paid more and more attention to the development of vertical take-off and landing aircraft, and gave it the top ten categories of future key equipment for the U.S. military. Its ability to adapt to complex terrain and environments is what the US military values. The rest of the countries are also catching up with the pace of the United States, putting more energy in...

Problems solved by technology

[0006] The purpose of the present invention is to provide a layout and control method of a distributed power tilting wing aircraft, to solve the problem of aerodynamic interference between the rotor and the wing and the problem of the reliability of the mode conversion control. The excellent controllability of the propulsion system and the vertical take-off and landing capability of the tilting wing aircraft are well combined to form a brand-new model scheme.
