Abstract:

The methods and results of the study of the effects of operational SST maneuvers on sonic boom are contained in three volumes. Volume III describes the computer program, Sonic Boom Propagation in a Stratified Atmosphere, written in FORTRAN IV for processing on an IBM 7090 or CDC 6600 and plotting on a CALCOMP digital incremental plotter. It provides the capability to calculate sonic boom pressure signatures generated by arbitrary maneuvering airplanes in horizontally stratified atmospheres with wind. Author
