초록

In this paper, Fly robot with electric power, a kind of Unmanned aerial vehicle (UAV), is considered as an autonomous hovering platform, capable of vertical lift-off, landing and stationary hovering. This aircraft has four rotor and DC motors of electrical Power, which is capable of Omni-direction for indoor application. In the earlier days of vertical flight experimentation developers looked at the intuitively easy control functionality of 4 rotor designs. But we need to obtain design method of suitable structures and adequate components because the existing prototypes of 4 rotor-craft don't analyze the propeller, motor characteristic and propose a methodology to optimize this system. In design of propeller, experimental results show that thrust and power are relatively efficient at a pitch angel of 20 degree. To the conclusion, the design method and optimization method of the propeller, motor, frame, Blimp, which are the main design elements of the blimp type 4 rotor craft, were studied to optimize the existing Blimp 4 rotor craft body design method.
