Paper Abstract

As part of the development of any computer simulation of procedures, equipment, or airspace, an appropriate model of aircraft must be selected. Due to the complexity and aviation safety-critical nature of these development efforts, a detailed survey of the current state-of-the-art in aircraft flight dynamic models is desired. Options include basic 3-D performance envelopes of various aircraft (e.g., acceleration, deceleration, turn rate, and climb rate), high-fidelity models (e.g., proprietary aircraft manufacturer models), commercial-off-the-shelf models (e.g., Laminar Research's X-Plane and Microsoft's Flight Simulator), Government models (e.g., NASA or FAA), and originally developed six degree-of-freedom mathematical models. Here, the simple kinematics model (using basic kinematic relationships without considering the impact of aerodynamics), the small perturbation theory model (which uses only the known, non-dimensional aerodynamic properties of the aircraft), the total forces and moments method (which solves the complete set of nonlinear differential equations and requiring large tables describing aircraft parameters in different flight regimes), and blade element theory (which makes use of the aircraft's physical structure to calculate the aerodynamic forces and moments on thin strips of the aircraft) are reviewed.
