Abstract:

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.
