Embodiment Construction

[0041] The power output of the power unit of the aircraft has various forms: the power unit is directly connected to the rotor, and the rotor is directly driven by the power unit; the power unit indirectly drives the rotor to rotate through the pulley and the drive shaft; Two rotors. The embodiment of the present invention will be described in combination with drive shaft transmission.

[0042] aircraft embodiment

[0043] Such as figure 1 As shown, the aircraft 100 includes a fuselage 101 , a main rotor assembly 102 , a secondary rotor assembly 103 , a power plant (not shown) and a folding arm 104 .

[0044] Such as figure 2As shown, the main rotor device 102 includes a first main rotor device 1021 and a second main rotor device 1022, the auxiliary rotor device 103 includes a first auxiliary rotor device 1031 and a second auxiliary rotor device 1032, and the axis 1033 is the inclination of the auxiliary rotor device axis. The folder arm 104 includes a connecting arm 104...

Abstract

The invention provides an aircraft with convertible drive. The main rotor device includes the main rotor that can be positioned at a backward tilt position relative to the fuselage, and the disconnection mechanism that can connect or disconnect power to the main rotor; the auxiliary rotor device includes the auxiliary rotor and the auxiliary tilting mechanism; the diameter of the main rotor is larger than that of the auxiliary rotor. The diameter of the rotor; the main rotor is installed on the front side of the fuselage; the auxiliary rotor is installed on the rear side of the fuselage through the auxiliary tilting mechanism, and the auxiliary tilting mechanism drives the auxiliary rotor around the axis of the width direction of the fuselage in the height direction close to the fuselage Tilt between a first position and a second position close to the length of the fuselage. Along the length direction of the fuselage, the center of gravity of the aircraft is located between the center of the rotation plane of the main rotor and the tilt axis of the auxiliary rotor; the first main rotor and the second main rotor are symmetrically installed on both sides of the fuselage; The first auxiliary rotor and the second auxiliary rotor are symmetrically installed on both sides of the fuselage. It can flexibly switch between the flight modes of rotorcraft and multicopter.

Description

technical field [0001] The invention relates to an aircraft, in particular to an aircraft with a convertible drive mode and a flying method. Background technique [0002] Aircraft include unmanned aerial vehicles and manned aerial vehicles. Unmanned aerial vehicles are referred to as "drones" for short, which are unmanned aircraft controlled by radio remote control equipment or embedded programs. A gyroplane is a rotorcraft that utilizes the relative airflow during forward flight to blow the rotor to rotate to generate lift. Its forward force is directly provided by the engine driving the propeller. Cyclogyro is actually a kind of aircraft between helicopter and fixed-wing aircraft, and it removes outside the rotor, also has a pair of vertically placed propellers to provide forward power, and generally less wings are also housed in flight. To provide some lift, the gyroplane must roll and accelerate to take off. [0003] Current rotorcraft UAVs are relatively inefficient,...
