Abstract:

PCBoom3 is a PC-based program that computes single-event sonic boom footprints from any supersonic vehicle exercising any maneuver in a real atmosphere, including winds. The user specifies the aircraft, the maneuver, and the atmosphere. The primary output is the sonic boom footprint in terms of contours of equal overpressure or other amplitude metric on the ground, relative to the aircrafts position. PCBoom3 also generates sonic boom signatures, the pressure-time history of the boom at a particular location on the ground. Spectra of these signatures are also computed. The program is operated through a menu interface, which simplifies its use and the presentation of results. The program is designed for use by personnel who are planning specific supersonic missions where sonic boom will be an issue or who are investigating sonic boom incidents. While the program is relatively simple to operate, it provides access to analysis which requires an understanding of sonic boom phenomena. A copy of this program can be obtained by contacting AFRLHECB at 937 255-3605 x423 or downloading the file directly from the public website at www.afcee.brooks.af.milECnoisenoisemodels.htm.
