A tilt-rotor UAV

Abstract

The invention discloses a tilting-rotor unmanned aerial vehicle, comprising wings, ailerons, empennages, a fuselage, a power system, a control system, and a ground-to-air data link system, and the power system includes a power tilting mechanism, a motor and a propeller , the middle part of the wing is designed and installed with a pressure pulley and a free-steering guide ring. The fuselage adopts a load-bearing bulkhead and a full-skinned form. The bulkheads are connected and positioned by carbon tubes. To guide the circle, the middle section of the fuselage is equipped with a landing gear installation partition and an equipment compartment floor, which are connected with the middle section of the fuselage frame with tenons and tenons. The upper edge of the middle fuselage is opened with platform grooves, and the carbon tube beam grooves are made of laminates on the platform. It is connected with the wing spar with screws, and the upper edge of the tail of the fuselage has a platform groove, and is connected with the flat tail with screws. The invention has compact structure, improved reliability and is suitable for popularization and application.

Description

technical field [0001] The present invention relates to an unmanned aerial vehicle, in particular to a tilting rotor unmanned aerial vehicle. Background technique [0002] The tilt-rotor aircraft combines the features of fixed-wing aircraft and helicopters, and is vividly called the "hybrid" in the air. It has the functions of vertical take-off and landing of helicopters, hovering, front, rear and side flight, and high-speed cruise of fixed-wing aircraft. The characteristics of long range, showing extremely superior maneuverability, has a wide range of application prospects in military and civilian fields, and also lays a technical foundation for the future development of aircraft in the direction of intelligent aerial robots and dexterous aircraft. Marked by the U.S. V-22 "Osprey" aircraft entering service, the research on multi-mode aircraft has made a breakthrough, and initially played an important role in actual combat. [0003] A tilt-wing aircraft acts like a transver...

AI Technical Summary

Problems solved by technology

Due to the unique design of the tilt-rotor aircraft in terms of power plant and structural layout, especially the influence of its power tilt angular velocity on the stability and control characteristics of the aircraft, it is significantly different from traditional aircraft. Therefore, the tilt-rotor The mathematical modeling and control problems of aircraft are much more complicated than traditional aircraft

The current theoretical research, especially the research on the dynamic process of power tilting, is still not perfect, which leads to the obvious lack of reliability and maintainability of the current tilt-rotor aircraft, and the design method of flight safety needs to be improved

[0004] In the working mode of the scheme of using two independent engines to work at the same time, it is very likely that the entire aircraft will crash due to an engine accident at one end
