Improved Dynamic Models for Air Combat Analysis.
Abstract
This report summarizes a multi-year research effort to develop improved dynamic model for air combat analysis. Reaching this objective is demonstrated by providing a zero-order feedback solution to the three-dimensional medium range air-to-air interception engagement, formulated as a zero-sum differential game. Using realistic aerodynamic and propulsion models, control strategies are expressed in a feedback form expressing explicitly the dependence on the measurable state variables and aircraft performance parameters The successive analysis is based on an innovative, variable modelling approach applying the method of forced singular perturbations. An imaginary air defence scenario serves as an illustrative example, showing the efficiency and the usefullness of the method for a rapid systematical parametric study. The accuracy of the zero-order feedback approximation and for most cases higher order terms may not be needed. Such corrective terms can be obtained, if necessary, by additional off-line computation. Computing the zero-order feedback strategies requires a minimal effort and presents therefore an extremely attractive candidate for real time implementation onboard of advanced fighter aircraft. It is, therefore, recommended to incorporate the implementation of the FSPT algorithm for optimal medium range air combat strategy in a future flight test program. (Author)
