摘　　要：螺旋桨动力试验的目的在于获得螺旋桨滑流影响(间接影响)。由于滑流影响量与直接影响量直接相关,因此在试验前应对直接影响量进行校准,在试验过程中应扣除直接影响。结合某带动力试验任务,对CARDC的4m×3m风洞带动力试验技术进行了改进,完善了单体试验(即校准试验)方法及全机试验时螺旋桨直接影响扣除方法,使试验结果更趋合理。The purpose of the test for aircraft with propeller is to obtain the effects due to slipstream. Because of the relation of slipstream and propeller power, the effects of propeller power must be adjusted and deducted in test. The test method with the propeller was improved in 4m × 3m wind tunnel of CARDC, the means for monomer test was perfected and the effects were deducted on aircraft due to propeller power. The resuhs are in accordance with the theories.
