A Cyclogyro-based Flying Robot with Variable Attack Angle Mechanism

Abstract

We develop a cyclogyro-based flying robot with a new variable attack angle mechanism. Cyclogyro is a flying machine which is supported in the air by power-driven rotors, which rotate about a horizontal axis, like the paddlewheels of a steamboat. Machines of this type have been designed by some companies, but there is no record of any successful flights. The proposed new variable attack angle mechanism has an eccentric point that is different from a rotational point. The main feature of the mechanism is to be able to change attack of angles according to the rotational angles of the cyclogyro without actuators. The lift and drag forces of the robot are calculated and measured through simulations and experiments. The simulation and experimental results show that the new mechanism generates positive lift forces at any rotational angles of the cyclogyro.
