Preliminary Infrared Radiation Emissions Prediction (PIREP). Volume II. User Manual
Abstract
PIREP (Preliminary Infrared Radiation Emissions Predictions) is a computer routine for providing preliminary IR signature estimates for turbojet, turbofan and turboshaft engines. The peak plume and hot parts infrared emissions can be made available as part of the output for each and every engine, cycle, and flight condition at low cost to the user. In this way estimates of susceptibility to missile threats can be included as an integral factor in preliminary engine design and realistic efforts can be made to select cycles which present low IR signatures to specific threat environments. Extended PIREP can also evaluate the suppression potential of several candidate engines or missions for relatively low cost during the early selection of phases of engine designs. The user can judge the potential of more advanced missiles and calculate lock on ranges for use in survivability studies or for comparison of different cycle/engine designs. Quick estimates are available to judge whether a candidate cycle can possibly meet given IR specifications before more expensive detailed studies are initiated. (Author)
