Book Description
Beskriver detaljeret flystøjs påvirkning af omgivelserne. Nutidens kraftige fly- og raketmotorer producerer voldsomme vibrationer (støj), som kan forårsage træthedsbrud i den omgivende struktur med mindre, der i konstruktionsfasen er taget højde for problemet.

Book Description
Over the last thirty years the European aeronautical industry has achieved a respected and internationally successful position. This EC-Aeronautics Research Series provides the opportunity to present the results of recent research projects in areas critical to the future competitiveness of the industry in world markets. It contains Technical Publications of the completed EC-Aeronautics pilot phase project work, which has been supported under Area 5 : "Specific Activities Relating to Aeronautics" of the Brite/Euram Programme within the Second Framework Programme of European Community Activities in the Field of Research and Technology Development (1989?1992). This volume presents the three projects which, under this pilot phase, carried out work in three areas of noise and acoustics technologies: exterior noise, cabin noise, and acoustics loads in relation to structural fatigue.

Book Description
This report summarizes the work conducted by the Structural Acoustics Integrated Technology Development (ITD) Team under NASA's High Speed Research (HSR) Phase II program from 1993 to 1999. It is intended to serve as a reference for future researchers by documenting the results of the interior noise and sonic fatigue technology development activities conducted during this period. For interior noise, these activities included excitation modeling, structural acoustic response modeling, development of passive treatments and active controls, and prediction of interior noise. For sonic fatigue, these activities included loads prediction, materials characterization, sonic fatigue code development, development of response reduction techniques, and generation of sonic fatigue design requirements. Also included are lessons learned and recommendations for future work.Beier, Theodor H. and Bhat, Waman V. and Rizzi, Stephen A. and Silcox, Richard J. and Simpson, Myles A.Langley Research CenterACOUSTICS; RESEARCH AND DEVELOPMENT; CIVIL AVIATION; SUPERSONIC WIND TUNNELS; ACOUSTIC FATIGUE; TURBULENT BOUNDARY LAYER; JET AIRCRAFT NOISE; ENGINE INLETS; FINITE ELEMENT METHOD; NOISE PREDICTION (AIRCRAFT); ACTIVE CONTROL

Book Description
An analytical and experimental program was conducted to develop acoustic fatigue design criteria for aircraft structures subjected to intense noise in a high temperature environment. Equations for the dynamic response of a buckled panel were formulated for simply supported boundary conditions using large deflection plate theory. Random amplitude acoustic fatigue testing of representative aircraft structure was accomplished at temperatures up to 600 F to provide data for correlation with the analytical results. Empirical design criteria are presented in the form of design equations and nomographs for predicting the combined thermal and dynamic response of aircraft structures.
