Helicopter

Abstract

A helicopter has a main rotor with propeller blades which is driven by a rotor shaft and which is hinge-mounted to this rotor shaft. The angle between the surface of rotation of the main rotor and the rotor shaft may vary. A swinging manner on an oscillatory shaft is essentially transverse to the rotor shaft of the main rotor and is directed transversally to the longitudinal axis of the vanes. The main rotor and the auxiliary rotor are connected to each other by a mechanical link. The swinging motions of the auxiliary rotor controls the angle of incidence (A) of at least one of the propeller blades of the main rotor.

Description

RELATED APPLICATION[0001]This application claims priority to Belgian Patent Application No. 2006 / 0043 entitled AUTOSTABIELE HELICOPTER by Alexander VAN DE ROSTYNE, which was filed on Jan. 19, 2006. The contents of that application are incorporated by reference herein.BACKGROUND[0002]The present disclosure concerns an improved helicopter.[0003]The disclosure concerns a helicopter generally. In particular, but not exclusively it is related to a toy helicopter, and in particular to a remote-controlled model helicopter or a toy helicopter.SUMMARY[0004]It known that a helicopter is a complex machine which is unstable and as a result difficult to control, so that much experience is required to safely operate such helicopters without mishaps.[0005]Typically, a helicopter includes a body, a main rotor and a tail rotor.[0006]The main rotor provides an upward force to keep the helicopter in the air, as well as a lateral or forward or backward force to steer the helicopter in required directio...

AI Technical Summary

Benefits of technology

"The patent text describes an improved helicopter design that is more stable and easier to operate. The design includes a main rotor and a tail rotor, and an auxiliary rotor that is driven by the main rotor and can be controlled to adjust the angle of incidence of the propeller blades. This design allows the helicopter to quickly stabilize itself and requires less pilot experience to operate. The text also mentions that the helicopter can be equipped with a gyroscope or other stabilization system to compensate for small variations in the resistance torque of the main rotor. Overall, the patent aims to make helicopters safer and more stable for flying without the need for a pilot."

Problems solved by technology

It known that a helicopter is a complex machine which is unstable and as a result difficult to control, so that much experience is required to safely operate such helicopters without mishaps.

The main rotor has a natural tendency to deviate from its position, which may lead to uncontrolled movements and to a crash of the helicopter if the pilot loses control over the steering of the helicopter.
