25TH INTERNATIONAL CONGRESS OF THE AERONAUTICAL SCIENCES THE INVESTIGATION OF CYCLOGYRO DESIGN AND THE PERFORMANCE Hu Yu, Lim Kah Bin, Tay Wee Beng Department of Mechanical Engineering, National University of Singapore Keywords: Cyclogyro, Cycloidal Propeller, Unsteady Vortex Lattice Method Abstract A tail rotor is installed to balance the torque caused by main rotor. As shown in Fig. 2, the The investigation over several possible coclogyo tail rotor in this case also generated lift which designs was performed in the paper. The unloads the main rotor and save power. This is concept of cyclogyro has existed almost 100 also superior to helicopters since helicopters years, but still more research are needed. The waste power to balance the main rotor torque. effects of taper ratio, aspect ratio and winglets The major disadvantage of the cycloidal are investigated in this paper. The comparison propeller is that it is much heavier than screw between different designs shows that the tapered propellers since big strut was need
