Abstract
A comprehensive study is being conducted to establish the sonic boom picture for the NASP X-30 vehicle in terms of its configuration and flight characteristics. The basic thrust of this study is to ascertain whether a sonic boom issue exists with the X-30 and, if so, to define its magnitude and recommend approaches to mitigate the problem. The purpose of this paper is to provide the results of the study findings that begin with the applicability and limitations of sonic boom prediction methods to the X-30 configuration and flight profiles, an indication of the transition focus booms on ground overpressures, and an assessment of the influence of the atmosphere on boom propagation. Sonic boom signatures, overpressure levels, and footprints are presented and comparisons are made to the existing sonic boom data base that includes F-104, SR-71, Concorde, XB-70, and STS Orbiter sonic boom measurements extending out to about a Mach number of 23 and altitudes to about 250,000 feet. In addition, a comparison is made of the X-30 configuration in terms of its shape factor with current vehicles so as to provide an indication of the sensitivity of vehicle geometric changes on sonic booms and their minimization. The significant effects vehicle climb angle can exert on the ground overpressures is also discussed.
