Single-rotor helicopter without tail rotor

Abstract

The invention discloses a tail-rotor-free single-rotor helicopter, and relates to the technical field of helicopters and unmanned aerial vehicles. The tail-rotor-free single-rotor helicopter comprises a helicopter body, an electrical cabin is arranged in the helicopter body, and a fixing device is mounted on the helicopter body through screws; during use, the torque of the lift folding rotors is balanced through the course wind wheels, and the aircraft body is compact in structure; the upper attitude wind wheel and the lower attitude wind wheel are controlled through the upper attitude driving motor and the lower attitude driving motor, so that the attitude of the aircraft body is adjusted, and decoupling control over the dynamics of the aircraft body can be achieved; in addition, the folding rotors and the helicopter body are directly connected with the helicopter body through the motors and the motor bases, a traditional helicopter hinge mechanism is optimized, the structural connection strength and folding and unfolding reliability of the helicopter body are improved, and the axial overload impact resistance of the helicopter body is enhanced. The application of unmanned helicopter launching deployment in narrow space, high-speed ground and air maneuvering platform cluster deployment and urban narrow roadway launching deployment is expanded.

Description

technical field [0001] The invention relates to the technical field of helicopters and unmanned aerial vehicles, in particular to a single-rotor helicopter without a tail rotor. Background technique [0002] A helicopter is a type of aircraft that flies by rotating its rotors. According to research by Western scholars, the Chinese toy bamboo dragonfly is the prototype of modern helicopters, which was born in the Warring States Period in 400 BC. Afterwards, the bamboo dragonfly was brought to Europe by Western missionaries, which inspired the design of Leonardo da Vinci during the Renaissance and created the prototype of the modern helicopter. In 1940, Russian Sikorsky tested the first practical manned helicopter VS-300 in the United States, which established the classic structure of modern helicopters. VS-300 is mainly composed of main lift rotor, tail rotor, mechanical hinge mechanism and airframe. [0003] Existing helicopters are composed of main rotors, tail rotors, a...

AI Technical Summary

Problems solved by technology

[0003] Existing helicopters are composed of main rotor, tail rotor, body and mechanical hinge structure, and the volume is difficult to reduce; in order to reduce the size of helicopters and meet the requirements of narrow space use, people have developed coaxial helicopters; coaxial helicopters use upper and lower rotors Instead of the main rotor of the original helicopter, there is strong aerodynamic interference between the upper and lower rotors, resulting in low aerodynamic efficiency

[0004] In addition, helicopters can generally only be released and deployed from a stationary open platform or a relatively stationary open ship platform, and cannot be deployed in narrow alleys of dense buildings in urban areas, difficult to pass through dense tree canopies such as rainforest forests, and cannot be deployed from high-speed ground vehicles and Aerial vehicle release; in order to expand the deployment and release platform and work field of the original helicopter, so that the unmanned helicopter can meet the above complex application environment, it is necessary to increase the initial speed of the unmanned helicopter from the above-mentioned carrying platform, and adapt to the high pressure generated by the platform gunpowder gas. Overload launch requirements

[0005] In the traditional helicopter structure, the rotor hinge mechanism is an important part of the helicopter, which plays the role of transmitting power to adjust the attitude; the rotor hinge mechanism is connected together through clearance fit, and the connection process determines that the hinge mechanism cannot withstand strong impact deformation and cannot To adapt to the severe impact caused by the launch of gunpowder and gas separated from the platform

[0006] In order to solve the problems existing in the technical background, the present invention proposes a tailless rotor single-rotor helicopter to solve the application and deployment problems of the above-mentioned tailless rotor single-rotor helicopter high-speed motion platform and complex environmental conditions
