Abstract

The principles of flow generation in ventilated-wall transonic test-section are briefly reviewed. The application of auxiliary suction is shown to have remarkable advantages in speed control and the reduction of diffuser horse power. Tests in a small scale transonic wind tunnel show how suction and wall divergence can be utilized in an optimum fashion in the subsonic as well as supersonic range of operation.
