A Refined and Less Conservative Day-of-Launch Atmospheric Flight Loads Analysis Approach
Abstract
A day-of-launch atmospheric flight loads analysis approach that reduces conservatism by better defining the components of flight loads that have to be treated statistically and those that can be established with measured wind profiles just prior to launch is described. The approach introduces the concept of removing from measured day-of- launch winds the rapidly varying features, and only using the more slowly changing components in day-of-launch placard calculations. The proposed approach takes advantage of a recently-developed methodology that defines the spectral boundary, as a function of time, between wind components that can be considered slowly varying and those that change rapidly and, hence, have to be addressed statistically.
