STUDY OF NUMERICAL INTEGRATION TECHNIQUES FOR REAL-TIME DIGITAL FLIGHT SIMULATION.

Abstract

A comprehensive and rigorous mathematical analysis of numerical integration techniques for real-time digital flight simulation is presented. Accuracy and efficiency of methods as well as stability of numerical solutions are examined in detail. These investigations allow the subject of 'best' integration methods and their derivation to be pursued. 'Best' methods based on accuracy/efficiency and on stability are developed; in addition, the Stability Chart and Z-Transform approaches are examined. This study allows certain evaluational techniques to be derived. Notable among these are a technique for evaluating any integration method and a technique for deriving a 'best' method for a given digital flight simulation problem. A demonstration section is included wherein the utility of these techniques is established. (Author)
