Abstract: In this paher, the behaviors of flexible and rigid thrust stand used in wind tunnel test are introduced. Impossibility for the flexible thrust stand to obtain high measurement accuracy is discussed, but it is not the situation in a rig test. Some differences are caused by different working medium used in the tests.
