Abstract
Last year, we succeeded in maiden flight of Aerobatic Airship Robot (AAR) which was equipped with the cycloidal propeller thruster, but we found that the thruster didn't produce enough thrust that enabled the robot fully aerobatic. Therefore, in this time, we improved the cycloidal propeller in order to produce more thrust and calculation was made to estimate the performances of the cycloidal propeller whose rotational speed is higher and the angle of attack is larger than that developed in the last year.
