dc.description.abstract	A preliminary investigation made with temporary test liners in the RAE 3ft x 3ft tunnel has confirmed that there are significant advantages in using working sections with sound-absorbing walls for aeroelastic tests at subsonic and transonic speeds. In particular, tunnel resonances and flow unsteadiness can be reduced just as effectively in a large wind tunnel as in the small tunnel used for the previous pilot tests. The reduction in flow unsteadiness obtained with sound-absorbing walls significantly improved wing buffeting measurements on an ordinary wind tunnel model.	en_US
