Problems solved by technology

Although research on four-rotor unmanned aerial vehicles has begun to flourish, there has been no progress in aircrafts such as the U.S. "Osprey" helicopter that have both the vertical take-off and landing function of a helicopter and the horizontal high-speed cruise function of a fixed-wing aircraft.

Abstract

The invention relates to a tilted four-rotor aircraft. The tilted four-rotor aircraft comprises a fuselage, wherein the fuselage is provided with a front wing and a rear wing, two ends of the front wing and two ends of the rear wing are respectively provided with a set of rotor system, and the front wing and the rear wing are respectively and internally provided with a worm-wheel shaft which passes through the fuselage and is used for driving a rotor wing system to do tilted rotating motion; each set of rotor wing system comprises a direct-current brushless motor and a propeller, and the direct-current brushless motor is arranged at the end of the worm-wheel shaft and provided with the propeller. Compared with a conventional tilted double-rotor aircraft, the safety and reliability of the tilted four-rotor aircraft provided by the invention are higher; four rotors have strong lift force, so that the payload, flight radius and flight stability are all greatly improved. The tilted four-rotor aircraft provided by the invention can realize three flight modes, namely a helicopter mode, a transition mode and a horizontal propulsion mode, and has the characteristics of simple structure, high strength, reliable function realization and the like.

Description

technical field [0001] The invention belongs to the technical field of unmanned aviation, and in particular relates to a tilting quadrotor aircraft. Background technique [0002] Since the reform and opening up, my country's aviation industry has made great progress and has become one of the top in the world. However, there is still room for further development in some major areas, the most typical being advanced UAV technology. While the U.S. government has drastically reduced defense spending, the cost of UAV equipment and research and development has not decreased but increased. Nearly 30 other countries, such as Israel, Russia, the United Kingdom, France and South Africa, have also formulated UAV development routes. Figure, to promote the development of unmanned aerial vehicles, the extremely important strategic position of advanced unmanned aerial vehicles can be seen, but the current research on advanced unmanned aerial vehicles is not enough. Although the research on...
