PARCS3 is an advanced computer code for the modeling and analysis of missile plume radar cross section (RCS) and RF attenuation. It integrates and upgrades the capabilities of the earlier PARCS+ (incoherent radar cross section) and PRATT (RF transmission attenuation) codes, extending support to 3D flowfields. PARCS3 is designed to work with plume flowfield properties generated by codes such as SPF-III, Vulcan, US3D, and others.
The Enhanced MODEX Toolkit is a user oriented interface to the application of Model Extrapolation in the development of threat signature databases. Model extrapolation uses government standard models to extrapolate IR and UV signature data to operational flight conditions. Threat signature databases developed using the E-MTK provide for a complete threat characterization over a flight trajectory envelope which is more complete than available data and more accurate than calculations alone. E-MTK is trusted by the Advanced Missile Signature Center.
MorphEx is a flowfield morphing software developed by PST to efficiently generate 3D plume flowfields. It interfaces with plume flowfield simulation tools such as SPF-III, Vulcan, US3D, and others. MorphEx uses landmark-based warping and interpolation techniques, along with mass and energy corrections, to produce accurate intermediate flowfields between high-fidelity simulations or extrapolate beyond available models, dramatically reducing the computational cost of comprehensive threat characterization.
SPF-III is a JANNAF standard computer code used for predicting the gas dynamic structure of single-phase and two-phase low altitude (<~70 km) rocket exhaust plumes. SPF is used to predict plume signatures and plume/vehicle interaction phenomena, and incorporate the effects of flow over the missile body and in the base separated region. SPF-III is distributed to the US propulsion community by CPIAC.
