A comparison of the response of a captive carried store to both reverberant and progressive wave acoustic excitation

PDF Version Also Available for Download.

Description

Stores carried on high performance military aircraft are exposed to severe vibroacoustic environments which are caused by several different sources. Two methods available for simulating the acoustic portion of this environment in the laboratory are reverberant chambers and progressive wave tubes. The literature indicates that structures will respond differently to each of these acoustic sources as a function of frequency for the same Sound Pressure Level. Sandia National Laboratories participated in a test program that obtained acoustic data for a common store using both types of acoustic excitation. The purpose of this paper is to present the results from those ... continued below

Description

Stores carried on high performance military aircraft are exposed to severe vibroacoustic environments which are caused by several different sources. Two methods available for simulating the acoustic portion of this environment in the laboratory are reverberant chambers and progressive wave tubes. The literature indicates that structures will respond differently to each of these acoustic sources as a function of frequency for the same Sound Pressure Level. Sandia National Laboratories participated in a test program that obtained acoustic data for a common store using both types of acoustic excitation. The purpose of this paper is to present the results from those tests in such a way so as to document the existence or absence of any significant differences in the coupling efficiencies for these acoustic sources.
