Abstract: One factor which influences the radiation of jet noise is the interaction with the heated moving flow of a parallel twin jet. Because of the temperature and flow discontinuity between the jet ...

Abstract: An analytical model to estimate the shielding of noise emitted from a point noise source has been developed assuming the shielding jet to be a cylinder of constant radius with uniform flow ...

Abstract: The low gravity environment of the Space Station is suitable for experiments or manufacturing processes which require near zero-g. Such experiments are packaged to fit into rack-mounted modules ...

Abstract: Relative and absolute shaft vibration data have revealed that the commonly made assumption of rigidly supported bearings may be grossly inaccurate, especially for fans, generator sets, and natural ...

Abstract: Many in-space research experiments require the microgravity environment attainable near the center of mass of the proposed space station. Since dynamic disturbances to the surrounding structure ...
