Abstract

The generation of high-fidelity imagery of infrared radiation from missile and aircraft exhaust plumes is a CPU intensive task. These calculations must include details associated with the generation of the plume flowfield and transport of emitted, scattered, and absorbed radiation. Additionally, spatial and temporal features such as mach discs, intrinsic cores, and shear layers must be consistently resolved regardless of plume orientation to eliminate nonphysical artifacts. This paper presents computational techniques to compute plume infrared radiation imagery for high frame rate applications at the Kinetic Kill Vehicle Hardware-in-the-loop Simulator facility located at Eglin AFB. Details concerning the underlying phenomenologies are also presented to provide an understanding of the computational rationale. Finally, several example calculations are presented to illustrate the level of fidelity that can be achieved using these methods.
