【Abstract】 The optimum angle was acquired, and the airflow power and efficiency of the turbine was investigated by the air dynamics theory and the angle kept transforms of the complex variable function in order to improve the character of the equipment and raise its efficiency .According to the result of testing ,the establishment of the mathematical model and the method of the analysis is correct .The total efficiency of the new product was up 13 55% and the noise down 4 dB,so the character of the product was improved.更多还原
