Formulation of the Equations of Motion of a Deformable Aircraft Using Lagrange's Equations in an Arbitrary Non-Inertial Frame of Reference

Abstract

The equations of motion of a deformable aircraft are developed in detail from Lagrange's equations for a non-inertial frame. Particular account is taken of the influence of the propulsive and effective forces produced by power units containing rotating parts. The development ventures to a certain extent into the non-linear regime. By an appropriate choice of deformation modes the principal frame of reference can be specified as, for example, mean-body axes or body-fixed axes.
