Development and quality control method of variable torque propeller for wind tunnel power simulation

Abstract

Abstract In order to study the comprehensive influence of propeller power and sea surface effect of a seaplane, a composite material variable torque propeller for wind tunnel power simulation was developed. In order to make the quality of wind tunnel test data meet the standard of engineering application and control the quality of propeller products, a quality control method was developed to control the quality of design, checking, manufacturing, verification and operation of the propeller in all stages. In this paper, the research and development process and quality control method of the propeller, tests and the detection results, as well as the application test are described in detail. The results show that the quality control method described in this paper can be used to design and manufacture the propeller products which match the technical indicators, and the power simulation system composed of the propeller can exert slipstream influence on a certain seaplane under various working conditions, so as to meet the requirements of the study on the comprehensive influence of propeller power and sea surface effect of the aircraft.
