Effect of Moment of Inertia and Aerodynamics Parameters onAerodynamic Coupling in Roll Mode

Abstract

The influence of moment of inertia and aerodynamic parameters on the aerodynamic coupling in rolling mode has been analyzed for Aircraft F-94A (case study) for different rolling rate in rolling mode , the equations of motion for aircraft has been analyzed to get the required equations of motion for aerodynamic coupling. The stability of these equations has been tested by Routh Discriminate.The influence of moment of inertia and aerodynamic parameters on Routh Discriminate was clear, for example the wing span was the most positive influence on aerodynamic coupling stability.
