Agility Metric Robustness Using Linear Error Theory

Abstract

The robustness of agility metrics has been studied to determine the sensitivity of selected metrics to variations in initial conditions and uncertainties in physical characteristics and coefe cients. The selected metrics are time to roll through bank angle metric, time-averaged integral of pitch rate metric, and power onset/loss parameter. Each metric was evaluated with initial condition errors and parametric uncertainties of physical constants using linear error theory to validate the use of linear approximations to propagate the errors.
