Popis:	In the summer of 2002, small cracks were found in the liquid hydrogen feedlines of several Space Shuttle Orbiters. During the ensuing investigation, the unsteady flow environment surrounding the cracked liner less than a foot upstream of the shuttle main engine low pressure fuel pump was characterized extensively. The engine fuel inlet fluctuating pressure environment established from highly instrumented single-engine hotfire tests both with and without a flow liner simulator are described. Cavitation induced oscillation phenomena common in the inlet region of high -speed rocket engine turbopumps were mapped as well as fluid-resonant liner edge-tones. Correlation of the dynamically rich measured fluctuating pressure fields to dynamic liner strains are discussed.
