COMMERCIAL SUPERSONIC TRANSPORT PROGRAM. PHASE 2-A. COMPREHENSIVE REPORT. VOLUME 7-A. SONIC BOOM AND NOISE
Abstract
The Boeing Company has submitted for Phase II-A evaluation an airplane design, which, in its intercontinental and domestic versions, will provide economical supersonic transports meeting the diverse requirements of various operators and also meeting the design objectives of the FAA. The two models of the airplane are identical in all respects except for operational empty weight and maximum gross weight. Both the domestic and intercontinental versions meet or are lower than all noise objectives established by the FAA. Notable progress has been made during Phase II-A toward developing a supersonic transport that has both interior and exterior noise levels lower than present subsonic airplanes. Significant configuration changes from the Phase I proposal that have contributed to improvement are: (1) Development of engine inlet and nozzle noise suppression techniques with no performance penalty; and (2) Relocation of engines aft on the wing to reduce engine noise heard in the cabin. These changes, coupled with test-proven structural design concepts, will ensure a 50,000-hour fatigue life for the airplane with minimum weight penalty. This document presents the substantiating data for sonic boom, engine noise, interior noise, and sonic fatigue effect on structures.
