Heat-flux gage measurements on a flat plate at a Mach number of 4.6 in the VSD high speed wind tunnel, a feasibility test (LA28)

, 1975
The feasibility of employing thin-film heat-flux gages was studied as a method of defining boundary layer characteristics at supersonic speeds in a high speed blowdown wind tunnel. Flow visualization techniques (using oil) were employed.

Improvements on the Control, Data Acquisition and Processing System for the Roll Damping Rig of 1.2m Wind Tunnel

, 2010
The control system was developed to control, acquire and process the data from the specially designed Roll Damping Rig to measure the roll damping derivatives of aerospace vehicle models. Steady roll technique was used for these measurements in the NAL 1.

Flow quality improvements in a blowdown wind tunnel 13; 13;

, 2001
Acoustic baffles installed in the extended settling chamber of the NAL 1.2-m tunnel have substantially reduced the noise levels in its settling chamber and the SW test section. The quieter test-section flow has led to (1) a substantial improvement in the
