Laser Scattering Applications Development Test in AEDC Tunnel B at Mach Number 8.

Abstract

Free stream and local flow field measurements on a blunt (0.375-in. radius) nose 5-deg cone were made in Tunnel B at Mach number 8. The nonintrusive flow field measurements were made using various laser scattering optical systems to determine the free stream and local flow field particulate concentration and size distribution, the nitrogen molecule number density, and the local stream velocity using a Fabry-Perot interferometer system. The 5-deg cone pressure distributions were used to confirm the test section Mach number and to produce a known local flow field which could be used to demonstrate potentially useful laser scattering measuring techniques.
