Abstract

Speed, power and flow inclination calibration tests run in the Merrill-GALCIT wind-tunnel are described and results presented. A description of the new balance-system is included. Turbulence measurements with hot-wires were made in the tunnel at various speeds and with various screen configurations.

Tests run in a small scale model of the projected cooperative wind-tunnel at subsonic and sonic velocities are briefly described. A suggestion for introducing variable working- section walls in the new scale model undergoing construction is discussed and presented.
