Abstract
The impacts of propellers on aircraft aerodynamic characteristics are crucial in propeller-driven aircraft design, which mainly consist of three parts including the propellers' pulling force & rolling moment, the propellers' radial force (when its axis have an angle with airflow) , and the indirect influence induced by accelerated airflow behind the propeller. The wind tunnel test method of propeller's radial force isn't mature in domestic. Combined with the design of aircraft, this paper mainly focused on the research of the essence of propeller radial force and its simulation method in wind tunnel, and advanced a simulation method of propeller radial force in wind tunnel based on propeller's direct simulation method. Further more, correction of propeller radial force test result was made by theory and tests, which included the upwash and other influence factors, and obtained available propeller radial force data for engineering use. The research is an important example in general aerodynamic design of similar propeller-driven aircraft.关键词
