Measurements of flow quality in the Ames 2*2 ft transonic wind tunnel
Until now there has not been a systematic study of the turbulence flow quality despite the fact that it was originally built as a prototype of the Ames lift wind tunnel. Previous testing has been carried out in an unknown freestream environment. This lack of documentation is not limited to the Ames 2*2 ft wind tunnel, it is the case in practically all ground base test facilities. The need for improved fuel-efficient transports employing super-critical or LFC airfoils, for example, has increased the awareness of the possible influence of freestream turbulence on advanced experimental testing. This has already led to detailed flow quality measurements in two NASA transonic wind tunnels. The purpose of this study is to present results of a similar study in the Ames 2*2 ft transonic wind tunnel. This work is pertinent to fuel-efficient transports. 2 refs.
