Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] see figure 1 , the present invention comprises a fuselage 1, a pair of wings 2 and three groups of rotor systems with the same structure arranged on the fuselage 1, a pair of wings 2 are symmetrically arranged on both sides of the fuselage 1, each wing 2 It is connected with the fuselage 1 through the wing reinforcing rod 12, and the wing reinforcing rod 12 can enhance the stability; the two symmetrically arranged wings 2 are provided with a front rotor tilt axis 5 for driving the rotor system to perform tilting motion, and the front rotor system The rotor tilting shaft 5 passes through the fuselage 1 and is installed inside the wings 2 on both sides, which plays a certain supporting role. A group of rotor systems are respectively arranged at the two ends of the front rotor tilting shaft 5 . The rear end of the fuselage 1 of the present invention is p...

Abstract

The invention relates to a tilt-three-rotor craft. The tilt-three-rotor craft comprises a craft body, a pair of wings and three groups of rotor systems, wherein the wings are symmetrically arranged on two sides of the craft body, and the rotor systems are arranged on the craft body; a front rotor tilting shaft for driving the rotor systems to do titling motion are arranged in the wings, one group of rotor system is arranged at each of two ends of the front rotor tilting shaft, and the third group of rotor system is arranged at the rear end of the craft body. The tilt-three-rotor craft has the beneficial effects that vertical take-off and landing functions of a traditional helicopter can be realized, and a high-speed cruising function of the craft can be realized by tilting the three pairs of the rotors to the horizontal position; by utilizing three tilt rotors, the craft has good symmetry and high safety and high reliability; the three rotors have large lifting forces, so that the effective load, the flight radius and the flight stability are greatly improved. The tilt-three-rotor craft has the advantages of simple structure, high strength, reliability in realizing of the functions and the like.

Description

technical field [0001] The invention belongs to the technical field of unmanned aviation, and in particular relates to a tilting three-rotor aircraft. Background technique [0002] Since the reform and opening up, my country's aviation industry has developed rapidly and has already ranked among the top in the world. However, there is still room for further development in some major areas, the most typical being advanced UAV technology. At present, it has an extremely important strategic position for an advanced aircraft like the American "Osprey" helicopter that can realize vertical take-off and landing like a helicopter, and can also realize high-speed cruise like a fixed-wing aircraft. Tilting rotorcraft is a blind area of ​​current research, and it has high research value. At present, research on quadrotor aircraft is popular, but this quadrotor aircraft cannot tilt, cannot realize horizontal high-speed cruise function, and has a complicated design.
