Description:The objective of this sonic fatigue summary is to provide major findings and technical results of studies, initiated in 1994, to assess sonic fatigue behavior of structure that is being considered for the High Speed Civil Transport (HSCT). High Speed Research (HSR) program objectives in the area of sonic fatigue were to predict inlet, exhaust and boundary layer acoustic loads; measure high cycle fatigue data for materials developed during the HSR program; develop advanced sonic fatigue calculation methods to reduce required conservatism in airframe designs; develop damping techniques for sonic fatigue reduction where weight effective; develop wing and fuselage sonic fatigue design requirements; and perform sonic fatigue analyses on HSCT structural concepts to provide guidance to design teams. All goals were partially achieved, but none were completed due to the premature conclusion of the HSR program. A summary of major program findings and recommendations for continued effort are included in the report.Rizzi, Stephen A. (Technical Monitor) and Beier, Theodor H. and Heaton, PaulLangley Research CenterACOUSTIC FATIGUE; AEROACOUSTICS; AIRCRAFT STRUCTURES; FATIGUE TESTS; SUPERSONIC TRANSPORTS; AIRCRAFT DESIGN; STRUCTURAL DESIGN; BOUNDARY LAYERS; INTAKE SYSTEMS; EXHAUST SYSTEMSWe have made it easy for you to find a PDF Ebooks without any digging. And by having access to our ebooks online or by storing it on your computer, you have convenient answers with High Speed Research Program Sonic Fatigue.
