|Developers of the Standardized Plume Flowfield Model
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
|Co-Developers of the Missile Plume Radar Cross Section
Code (PARCS+ )
PARCS+ is a computer code used to calculate the incoherent radar cross section of a rocket exhaust plume. PARCS+ is an upgraded version of PARCS 2.1 (available from CPIAC). Both codes are designed to be used with a plume properties code such as SPF. PST teamed with Sutton and Company, Inc. in the development of PARCS+
|Developers of the Missile Plume RF Attenuation Code
PRATT is a computer code used to calculate the attenuation of RF transmissions (uplink and downlink) by the rocket exhaust plume. PRATT requires plume flowfield properties computed by a code such as SPF. PST worked closely with Victor Technology in the development of PRATT.
|Developers of the Model Extrapolation Toolkit (MODEX
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 MODEX Toolkit provide for a complete threat characterization over a flight trajectory envelope which is more complete than available data and more accurace than calculations alone.
