Influence of Wind Tunnel Noise on the Location of Boundary-Layer Transition on a Slender Cone at Mach Numbers from 0.2 to 5.5. Volume I. Experimental Metho... A study was conducted to investigate the effects of wind tunnel noise on the location of boundary-layer transition. The study was ca...
The turbulent boundary layer on the wall of a 9 by 7 foot wind tunnel was measured with 12 different transducers at Mach numbers of 1.6, 2.0, and 2.5. The results indicated that the wall surface-pressure-fluctuation field was more homogeneous at a Mach number of 2.5 than at Mach numbers ...
CONSTITUTION:Since a nozzle is axially symmetric (that is, cylindrical) a center body 5 to be inserted thereinto has an axially symmetric cross-sectional area so as to support the center body in a rectifying cylinder 9. A center body sup port section 8 is provided therein with a drive ...

In a supersonic wind tunnel, the contour of the nozzle, the second throat setting and the stagnation pressure controlled by the Pressure Regulating Valve (PRV) are fundamental parameters without which the required Mach number in the test section cannot be achieved. For operating the Variable Mach...
To conduct this unprecedented experimental investigation, an arc-heated hypersonic wind tunnel facility with 1-second test time is used for generating high Mach number (Mach 4.5, 6 and 9) and high-enthalpy flows of total temperature up to 3,500 K. An integrated model scramjet is installed in...
