- W2035561328 abstract "Recently, members of the Marshall Space Flight Center (MSFC) Fluid Dynamics Branch and Wyle Labs measured far-field acoustic data during a series of three reusable solid rocket motor (RSRM) horizontal static tests conducted in Promontory, UT. The test motors included the Technical Evaluation Motor 13 (TEM-13), Flight Verification Motor 2 (FVM-2), and the Flight Simulation Motor 15 (FSM-15). Similar far-field data were collected during horizontal static tests of sub-scale solid rocket motors at MSFC. Far-field acoustical measurements were taken at multiple angles within a circular array centered about the nozzle exit plane, each positioned at a radial distance of 80 nozzle-exit-diameters from the nozzle. This type of measurement configuration is useful for calculating rocket noise characteristics such as those outlined in the NASA SP-8072 “Acoustic Loads Generated by the Propulsion System.” Acoustical scaling comparisons are made between the test motors, with particular interest in the overall sound power, acoustic efficiency, non-dimensional relative sound power spectrum, and directivity. Since most empirical data in the NASA SP-8072 methodology are derived from small rockets, this investigation provides an opportunity to check the data collapse between a sub-scale and full-scale rocket motor." @default.
