Abstract

In the field of aeroelastic instabilities, experimental results obtained from dynamic models have been a vital source of information needed to verify the accuracy of prediction methods, establish design criteria and to determine the structural adequacy of flight vehicles. Recently, the use of modeling for vibration and sonic fatigue prediction has been investigated and results indicate that modeling may be a valuable technique. This paper covers, first, the historical background of dynamic modeling and the evolution to the current state-of-the-art of modeling methods and uses. A review and discussion of recent research efforts dealing with various modeling problems, including flutter models for inflatable structures, high angles-of-attack, high temperature environments, vibration and sonic fatigue prediction are presented. Also included are remarks concerning future requirements and problem areas where research is needed to assure the availability of adequate modeling technology for the potential dynamic problems of advanced flight vehicles.
