Abstract:

Surface pressures produced at distances of 150-300 meters from the launch of STS-5 are analyzed. The calculated attenuation, phasing and and spacial coherence of surface pressure observations are consistent with the pressure produced by acoustics propagating outward from a single, small source moving with the rocket. The OASPL estimates for STS-5, calculated from standard form spectra, point to low acoustic efficiency or axially asymmetric acoustics for the shuttle.
