Flight Loads Analysis with Inertially Coupled Equations of Motion

In this work an approach for simulation of a large passenger aircraft with high precision equations of motion and a new method of dynamic loads calculation is presented, which can be used for maneuver and gust loads analysis in the time domain. Equations of motion and equations of structural loads are derived from first principles. The consistent set of equations includes all inertial coupling terms and is tailored for direct integration of finite element models. A dynamic simulation of a large transport aircraft is used to show the influence of inertial coupling terms on simulation and loads computation.
