Thermo-Vibro-Acoustic Loads and Fatigue of Hypersonic Flight Vehicle Structure ( Book )
1 edition published in 2009 in English and held by 1 library worldwide
Research was completed in 1989. A three-phase study of the "Thermo-Vibro-Acoustic Loads and Fatigue of Hypersonic Flight Vehicle Structure" is being performed by Rohr Industries, Inc., McDonnell Douglas Corporation and Science Applications International Corporation. The Phase I Study (AFWAL-TR-89-3014) evaluated various hypersonic vehicle designs and identified potential fatigue related issues resulting from high temperature vibroacoustic loads. This report contains the results of Phase II. A typical trajectory calling for ascent to orbit in 15 minutes and a generic Blended Wing Body vehicle design have been identified. Detailed designs for forebody, ramp, stabilizer, and nozzle skin panels are developed. Aerothermal and acoustic loads are determined. Analysis is made to determine temperatures, mean stress, and dynamic stress in panels. The results show that aeroacoustic loading will be critical for the design of ramp, stabilizer and nozzle vehicle skin panels.
Sonic Fatigue Design Techniques for Advanced Composite Aircraft Structures ( Book )
1 edition published in 1980 in English and held by 1 library worldwide
A combined analytical and experimental program was conducted in order to develop a semi-empirical sonic fatigue design method for curved and flat graphite-epoxy skin-stringer panels. A range of multi-bay panels was subjected to high intensity noise environments in a progressive-wave tube. Shaker tests were also performed in order to provide additional random fatigue data. Finite- element analyses were carried out on the test panel designs, generating static strains and frequencies. Multiple stepwise regression analysis was used to develop the sonic fatigue design method. Design equations and a nomograph are presented. Comparisons of sonic fatigue resistance between graphite and aluminum panels were also carried out. The design method developed is presented as a self-contained section in this report and is suitable for practical design use.
