Computational Methods for Control and Optimal Design of Aerospace Systems (FY 91AASERT)

摘要

This final technical report contains a summary and highlights of the researchfunded by AFOSR under Grant F49620-924-0261, titled 'Computational Methods for Control and Optimal Design of Aerospace Systems (FY 91 AASERT)', for tbe period 1 June 1992 to 31 May 1995. This AASERT grant supported two graduate students to work on the following topics; (1) the development of shape optimization algorithms for flow tailoring with applications to the design of forebody simulators, and (2) control of fluid/structure interactions. A new sensitivity equation method was developed and integrated into an optimization package for optimal design and flow tailoring. This method was transitioned into software packages at several industrial and government sites. In addition, this research produced a new understanding of the role that dissipation plays in optimization based design, and produced a new framework to analyze convergence of algorithms based on approximations of sensitivity equations. The report contains a summary of these results and a list of papers produced during this period. (AN).
