摘要
Abstract
The method of measuring rotate speed with piston motor is used to judge the aerodynamic capability of manufactured propellers in engineering .But the method is not good in fact .Accordingly ,in base of results of rotate speed measured by piston motor in ground condition ,the aerodynamic characteristics of the same type of propeller in different velocities and rotate speeds ,such as efficiency ,thrust coefficient and power coefficient ,are measured in low‐speed wind tunnel test ,and flight emulation method is used to compute flight capabilities of the same UAV after getting the test data .Results show that the efficiency ,thrust coefficient and power coefficient of propeller are not directly in relation with the rotate speed measured in ground condition with piston motor by comparing the results in wind tunnel test and computation .Consequently ,the method of measuring rotate speed with piston motor is not crucial but only referenced in checkout method of UAV’s propeller .关键词
