Atmospheric Flight Gust Loads Analysis

Abstract

A new Monte Carlo atmospheric flight gust loads analysis approach is presented. The procedure uses forcing functions that were derived by extracting the turbulent, short-duration, non-persistent components of measured wind profiles. Over 1000 forcing functions were used in each analysis. The results were analyzed statistically to establish the 99.7 percent enclosure, 90 percent confidence level, load values. Results are presented for a medium lift launch vehicle and a heavy lift launch vehicle. Loads for various altitude bands, time of year, and the Eastern Range and Western Range launch facilities in the United States are compared. Also, the Monte Carlo results are compared to a prevalent synthetic gust analysis approach in use today.
