An experimental study on performance of curved-plate bladed rotor

This paper reports author’s experiences of technical assistance for developing countries.The authors proposed a curved-plate bladed rotors based on the design concept of an appropriate technology. From the wind tunnel test, the highest power coefficients both 3-bladed and 5-bladed rotors are around 0.35 as the same value for high performance solid propeller type bladed rotor. Thus, the proposed curved-plate bladed rotors will have good prospect not only for developing countries, but also for educational materials.
