Problems solved by technology

Helicopters occupy a high position in the aviation industry because of their great advantages of vertical take-off and landing, but they also have obvious disadvantages: the transmission mechanism is complex and heavy, and the cost is high
At present, there is no aircraft that combines the advantages of helicopters and autogyro. In view of this phenomenon, the present invention designs an unmanned autogyro that can take off and land vertically, which can be used for tasks such as military transportation and tourism.

specific Embodiment approach

[0020] When on the ground, the tilt rotor disc is parallel to the ground (such as image 3 As shown), the rotation speed of the tilt rotor is changed by controlling the motor speed in the nacelle through the control system. When the rotation speed reaches a certain value, the lift generated by the tilt rotor will balance the gravity of the autogyro, continue to increase the speed, and the autorotor The machine can take off vertically;

[0021] After rising to a safe height, start the engine located inside the fuselage of the autogyro through the control system, and the engine will drive the propeller to rotate. At this time, the autogyro will be thrust by the propeller, and the autogyro can fly forward. At this time The blades of the main rotor system will rotate automatically due to the effect of the incoming flow, the autorotation speed of the rotor will increase with the increase of the forward flight speed of the autogyro, and the lift generated by the rotor will also incr...

Abstract

The invention discloses an unmanned self-rotation rotorcraft capable of vertically taking off and landing. The rotorcraft is characterized in that blades are installed at the tail part of the rotorcraft, wings and short chambers which are installed at the outer ends of the wings are arranged on the two sides of a fuselage, a main rotor wing system comprises a main rotor wing manipulating system, rotor wing heads and main rotor wing blades, the rotor wing blades are installed on the tops of the main rotor wing manipulating system through the rotor wing heads, tilt rotor wing systems comprise atilt rotor wing manipulating system which is installed at the front end of the short chamber, hubs and tilt rotor wing blades, and the short chamber is internally provided with steering engines whichare used for achieving the tilting adjustment and rotary driving of the tilt rotor wing systems and motors. The rotorcraft combines the advantages of a helicopter and has the advantages that the structure is simple, the cost is lower, the operation is convenient, the rotorcraft has vertical take-off and landing capability, minimum altitude flight capability and flexible manipulation, and thereforethe maneuverability of the self-rotation rotorcraft is greatly improved to help popularization and use.

Description

technical field [0001] The invention relates to an unmanned autogyro capable of vertical take-off and landing, and belongs to the technical field of aviation vehicles. Background technique [0002] In recent years, with the rapid development of the aviation industry, various aircrafts emerge in endlessly. Helicopters occupy a high position in the aviation industry because of their great advantages of vertical take-off and landing, but they also have obvious disadvantages: the transmission mechanism is complex and heavy, and the cost is high. As an aircraft with a longer history than helicopters, autogyro also has great advantages: simple structure and low cost. At present, there is no aircraft that combines the advantages of helicopters and autogyro. For this phenomenon, the present invention designs an unmanned autogyro that can take off and land vertically, which can be used for tasks such as military transportation and tourism. Contents of the invention [0003] Purpo...
