Abstract

An AGA Thermovision® System 680 was used in studying the IR signature from an axisymmetric nozzle after-body model at transonic Mach numbers (M = 0.0, 0.6, 0.9, 1.3). Radiance measurements from the exhaust plume in the CO2 emission band were observed through a narrow spectral filter (4.21-4.41 µm). Results are presented in the form of axial and radial plume radiance profiles. Such spatially resolved plume radiance measurements serve as a flow visualization to reveal shock structure and as a baseline for plume radiation model prediction.
