Abstract

A flexible and versatile holographic interferometry system is being developed for the Rocket-dyne Hypersonic Flow Laboratory (RHYFL) which will be a free-piston shock tunnel operating in the reflected shock mode. The RHYFL's large test section allows testing of full scale engine components, simulating a true hypersonic flight speeds up to re-entry conditions. The holographic system incorporates a diffuse back-lighting along with both double plate and rapid double pulse methods to provide 3-D visualization of the flow field inside the test section, and it has been designed to obtain the qualitative data on mixing rates and density structures as well as the location and shape of the shock waves.
