Research Abstract

This research is concerned with the theoretical and experimental development on the aerodynamic and dynamic characteristics of flying vehicles with spinning circular wing. The study aims are to develop the following two subjects which are not examined so far and of academic interest.
(1) Aerodynamic characteristics of spinning circular wing
Aerodynamic center of the conventional airplanes is located near a quarter chord point, and negative pitching moment is generated around the point. The aerodynamic location and its moment are not known when the wing is rotated.
The wind-tunnel experiments were done on the circular wings with several aerofoils. The results show that the aerodynamic characteristics with the Frisbee aerofoil are different from the Disk and other aerofoils because of the concave lower surface. Specifically, the Frisbee aerofoils has
* larger lift and drag coefficients, high stall angle of attack. and almost constant lift-to-drag ratio with angle of attack.
* low negative pit … More ching moment coefficient around the spinning axs, while the moments of the other aerofoils are positive.
* The effects of spinning of the wings on the surrounding air are negligible because of the unnoticeable unsymmetory between the right and left side streams.
(2) Dynamic characteristics of spinning circular wings
It is shown that the stability is improved with the increase of the spin rate. The ground trajectory of a flying Frisbee shows curved one on the left with left bank angle when the wing is rotating right on the top view. The left curved trajectory is caused due to a small positive pitching moment, which generates the change of the roll angle with the phase lag of 90 degrees. The derail examination from both experiment and simulation reveals that the pitching moment of Frisbee changes with the angle of attack from a small negative value to a small positive one around the angle of attack of 20 degrees. This causes the Frisbee curve on the left side during deceleration with high sink rate.
(3) Development of flight control theories
A number of the recent control theories such as the H infinity robust control, nonlinear control, control of time delay systems, and adaptive control are examined and the design methods of flight controllers are developed. Less
