Radiation Suite for Hypersonic Flows and Surfaces Detection

Abstract

We propose the acquisition of a state-of-the-art radiation suite for detection of high-enthalpy flows and high-temperature reactive surfaces. The suite is composed of a new-generation infrared camera, able to provide high-resolution surface temperature distributions and spectral signatures of high-temperature surfaces, and an ultraviolet to near infrared optical emission spectrograph equipped with high-resolution intensified cameras, enabling detailed detection of non-equilibrium flows and plasma radiation processes. The instruments will be operated across a range of inductively coupled plasma wind tunnels and reactors for hypersonic testing. The simultaneous spatial and temporal resolution of surface radiation and emissivity, near-surface gas composition and temperature, and freestream conditions is key to enable true validation data for nonequilibrium models of hypersonic environments. The new instrumentation will directly impact ongoing basic research on non-equilibrium gas-phase recombination, on finite-rate heterogeneous chemistry at catalytic surfaces, and radiation signatures from hot surfaces and wakes.
