STOL Aircraft Structural Vibration Prediction Method. Volume II. Acoustic Prediction Details and Additional Plots for Small STOL Aircraft

Abstract

Structural response predictions have been made for two important areas of STOL-type aircraft. The method was developed to significantly improve environmental prediction methods that have been used in the past. A mathematically rigorous spectral analysis approach was developed that simulated the structure with a finite element model and used correlated and calculated acoustic input data for the forcing function.
