Conceptual aircraft dynamics from inverse aircraft modeling

Abstract

This thesis presents a method of construe' ting a nonlinear dynamics model of a theoretical aircraft from the nonlinear batch simulation of an existing aircrew This method provides control law designers with a method of fabricating nonlinear models on which to test their control laws. The method involves the extraction of the aerodynamic and propulsive data from the existing simulation and their subsequent integration into a new nonlinear simulation. The subject aircraft from which the data is derived is a vertical/short-take-off-and-landing attack plane. The target aircrew to be modeled is a VSTOL uninhabited combat aerospace vehicle. The new model and simulation was successfully created and multiple test simulations were performed. The results show that this method is viable and produces a fairly accurate simulation with relatively little data from the original simulation.
