The PCBOOM computer program, described in this technical report, calculates the location and magnitude of sonic-boom overpressures on the ground due to supersonic flight under standard atmosphere and no wind-propagation conditions. The program is intended for environmental planners and engineers who may need to estimate the noise impact from individual flights of supersonic military aircraft. The program runs on a Zenith Z-248 personal computer and also should run on most similarly configured IBM-compatible computers. The program contains information for all current military aircraft and allows updating for additional aircraft. The user can select either 'Quick look' computations which assume steady-state flight or detailed ray-tracing calculations which can handle non-steady flight and sonic-boom focus conditions. Several types of simple maneuvers can be selected for computations; the program will also handle up to ten connected straight-line segments. Flight segments from the MOAOPS library of supersonic combat training flights may also be selected. User-specified output for printer, plotter or screen includes tables of overpressures and graphic display of the sonic-boom overpressure 'footprints' on the ground. The footprint plots show the location of all ray positions that exceed overpressures of a given level. Flight track, Mach number, and altitude profile plots are also provided. This report summarizes the technical basis for PCBOOM. Two other reports provide a program users/computer operations manual and a program maintenance manual.
