Book Description
A compilation has been made of all calibration data obtained since 1958 in the von Karman Gas Dynamics Facility's 12-Inch Supersonic Tunnel (D). Test section flow characteristics are presented for the nominal Mach number range from 1.5 to 5 over the available Reynolds number range. Along the axis of the test section for all contours the maximum variation in Mach number is within =0.01, and the average flow angles in pitch and yaw are less than 0.2 deg. Somewhat larger variations in Mach number and flow angularity are found off-axis. At the higher Mach numbers, significant changes in the average test section Mach number with decreasing Reynolds number are accompanied by corresponding changes in the tunnel boundary layer.

Aerodynamic Data Accuracy and Quality

Book Description
The wind tunnel continues to be the main instrument for providing experimental aerodynamic data to the aerospace industry and the aerodynamic researcher for the purpose of load and performance evaluation and for verification of theoretical results. In both cases it is imperative that the user has confidence in the quality of the results, which means that he must have information on what accuracy to attach to the data. The quality of wind tunnel results depends upon both the accuracy of measurements and the imperfections provided by the wind tunnel environment. Great strides have been made in recent years on measurement accuracy and as a rule this need no longer be of much concern if properly attended to. However, imperfections provided by the wind tunnel environment are still with us and these are today the main sources affecting the quality and accuracy of aerodynamic data obtained in a wind tunnel. It was the purpose of this symposium to try to define what accuracy has presently been achieved in modern facilities and to compare these achievements with the actual demands of the user.
