Evaluation of 3-D Turbulence Techniques for Designing Aircraft
Abstract
A recently developed multiple input power spectral technique is applied to predict the response of a C-5A aircraft to three-dimensional turbulence. Results are compared to the equivalent one-dimensional turbulence analysis, using corresponding C-5A dynamic response test data as a reference. Load variations range from an increase of 3% to a decrease of 14%. Because the coherence properties of the turbulence field are fully accounted for in the 3-d gust response analysis, theoretical results which depend upon the cross spectra between responses and probe-measured gust components tend to show a marked improvement over the 1-d case.
