Abstract:

The basic requirements for the development of a six-degree-of-freedom digital simulation model are outlined, and three coordinate systems are specified which are both adequate and convenient for such a development. The nontrivial coordinate transformations are shown. The equations of motion are developed, with indications of the standard assumptions. The principal forces and moments are discussed. The thrust misalignment effects are derived and the formulas for the jet damping moment are included. Aerodynamic forces and moments are discussed, and the necessary aerodynamic angles are defined. These forces and moments are described from the stability derivative point of view, and components of the major forces and moments are derived.
