Abstract

George C. Marshall's Saturn S-1C booster has a power output of 200 million acoustic watts for a period of 128 sec. A large number of static firings of this unique acoustic source are planned between 1966 and 1967. It is the purpose of this paper to show one method of utilizing, for acoustical investigation, the intense noise field generated during static firings of the Saturn vehicle. A testing facility, designated the Mobile Acoustic Research Laboratory (MARL), has been designed for positioning large test specimens in the field. The acoustical field around the Saturn booster is presently being defined by measurement and analytical techniques. It will be possible to obtain limited control of the intensity level and spectrum shape by choosing suitable locations in the region of the Saturn. Some of the projects planned for testing in the MARL are described.
