Aerodynamic coefficients approximations for arbitrary angles

Z. V. Didyk, V. A. Apostolyuk

Abstract


This paper addresses the whole angle approximations of aerodynamic coefficients. Several nonlinear approximations are proposed to describe lift, drag and side force coefficients in the range from 0 to 360 degrees based on accuracy and simplicity

Keywords


flight simulations; aerodynamic coefficients; nonlinear approximations
