摘要：	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 which 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.
