Sensitivity and Adjoint Methods for Design of Aerospace Systems

Abstract

This final technical report contains a summary and highlights of the research funded by the Air Force under AFOSR PRET Grant F49620-96-1-0329, titled "Sensitivity and Adjoint Methods for Design of Aerospace Systems". This research was conducted by the Air Force Center for Optimal Design and Control (CODAC), during the period 1 July 1996 to 31 December 2001. The Center conducts a wide range of research and educational programs, and promotes linkages between Air Force Laboratories, industry and university scientists. The PRET grant focuses on transition through industrial partnerships. During this period, CODAC researchers produced more than 115 scientific papers, made more than 150 presentations at conferences and colloquium and directed more than 20 graduate students and 7 postdocs. The research effort has produced several new computational tools for optimal design and these tools have already been transitioned into commercial software packages. Progress was made on a new sensitivity based method for estimating rotary stability derivatives. A new approach improved the efficiency of automatic differentiation when used in shape optimization. In the area of control, a new computational tool for controller reduction was devised and tested. This tool is based on proper orthogonal decomposition techniques. In addition, this report outlines some of the interactions between CODAC, industrial partners and Air Force facilities.
