Application of the Lateral and Longitudinal (Coupled) Equations of Motion to an Inertially-Slender Aircraft in Unsymmetric, Rectilinear Flight.

Abstract

The dynamics of an aircraft in flight may be represented by a set of six coupled non-linear equations of motion that are usually linearized about a symmetrical equilibrium position and divided into uncoupled lateral and longitudinal equations. The present high speed fighter aircraft requires a configuration that is prone to lateral instabilities which are not analyzed by the uncoupled equations. Solution of the coupled equations of motion is of considerable value because the cross-coupling effects may be determined and analyzed. For this study the F-4D aircraft was chosen as the physical model because of known stability difficulties. (Modified author abstract)
