ATA Engineering, Inc., in collaboration with IERUS Technologies, Inc., proposes the continued development of the Rotorcraft Advanced Signature Prediction (RASP) toolkit. This will involve extension of existing widely used, well-validated EO/IR toolsets to rotorcraft through a modular, variable-fidelity, hierarchical approach to signature analysis. To achieve this capability, the project team will integrate the NASA FUN3D unstructured CFD solver with the JANNAF Spectral and In-band Radiometric Imaging of Targets and Scenes (SPIRITS) and Fast Line-of-sight Imagery for Target and Exhaust Signatures (FLITES) EO/IR signature modeling tools, in addition to extending support for Standard Plume Ultraviolet Radiation (SPURC).The Phase II effort will focus on integration with the aforementioned EO/IR solvers and expansion of their support with the RASP toolkit, improving the toolkit’s physics modeling capabilities, and verifying the predictive accuracy of the toolkit. The effort will establish a variable-fidelity approach where modeling components, such as the inclusion of fuselage conjugate heat transfer, may be switched on and off in a hierarchical approach to ascertain the underlying sensitivities to the choice in numerical models. This approach also directly supports situations where advanced modeling parameters may not be known and lower-fidelity models are preferred.
