A methodology aimed at quantifying the admissible ranges of uncertainties in which relevant vehicle properties can be guaranteed is presented. The approach reduces the problem of determining the dynamic characteristics of the complete nonlinear system to an analysis of the robust stability of linear systems subject to uncertain parameters. Maximum acceptable uncertainties in terms of CLα and CMα have been identified, which can help to identify the needed level of accuracy in the aerodynamics model. The method's ability to identify the maximum admissible uncertainties and to address the areas of major concern is also highlighted.

Abstract

A methodology aimed at quantifying the admissible ranges of uncertainties in which relevant vehicle properties can be guaranteed is presented. The approach reduces the problem of determining the dynamic characteristics of the complete nonlinear system to an analysis of the robust stability of linear systems subject to uncertain parameters. Maximum acceptable uncertainties in terms of CLα and CMα have been identified, which can help to identify the needed level of accuracy in the aerodynamics model. The method's ability to identify the maximum admissible uncertainties and to address the areas of major concern is also highlighted.
