| Title: |
| Wings of the Future: The Potential of Shape Optimization |
| Lecturer: |
| Antony Jameson |
| Abstract: |
| A historic review of the aircraft design process will be given first. Then the case will be made for efficient shape optimization algorithms. After that, an efficient design methodology based on the control theory will be presented. The method can handle a large number of design variables efficiently because the cost of one design iteration is approximately one flow solution plus one adjoint solution. The formulation will be described in detail, and many "real world" design problems will be shown to demonstrate the capability of the method. Some new developments will also be discussed. |
 ANTONY JAMESON has authored or co-authored 260 scientific papers, and is the principal developer of the well known series of `flo' codes, which have been used throughout the Aerospace Industry. He was born in Gillingham, Kent in 1934. Much of his early childhood was spent in India where his father was stationed as a British Army Officer. He first attended school at St. Edwards, Simla. Subsequently he was educated at Mowden School and Winchester College. He served as a Lieutenant in the British Army in 1953-1955, and was sent to Malaya. On coming out of the army he worked in the compressor design section of Bristol Aero-Engines in the summer of 1955, before studying engineering at Trinity Hall, Cambridge University, graduating with first class honors in 1958. Subsequently he stayed on at Cambridge to obtain a Ph.D. in Magnetohydrodynamics, and he was a Research Fellow of Trinity Hall from 1960-1963.
On leaving Cambridge he worked as an economist for the Trades Union Congress in 1964-1965. He then became Chief Mathematician at Hawker Siddeley Dynamics in Coventry. In 1966 he joined the Aerodynamics Section of the Grumman Aerospace Corporation in Bethpage, New York. In this period his work was largely directed toward the application of automatic control theory to stability augmentation systems. Starting in 1970, he began to concentrate on the problem of predicting transonic flow. Existing numerical methods were not equal to the task, and it was clear that new methods would have to be developed. At that time limitations in computer capabilities also precluded any attempt to calculate the flow past a complete aircraft, but useful efforts could be made for simpler configurations such as aerofoils and wings.
In 1972 he moved to the Courant Institute of Mathematical Sciences at New York University, where he continued his work on transonic flow. In 1974 he was appointed Professor of Computer Science at New York University. He joined Princeton University in 1980, and in 1982 he was appointed James S. McDonnell Distinguished University Professor of Aerospace Engineering. He was Director of the University's Program in Applied and Computational Mathematics from 1986 to 1988. During the last decade Professor Jameson has devised a variety of new schemes for solving the Euler and Navier-Stokes equations for inviscid and viscous compressible flows, and has written a series of computer programs which have been widely used in the aircraft industry. He and his co-workers were finally able to realize their goal of calculating the flow past a complete aircraft in 1985, using a new finite element method.
In 1980 he received the NASA Medal for Exceptional Scientific Achievement in recognition of his earlier work on transonic potential flow. In 1988 he received the Gold Medal of the British Royal Aeronautical Society for his outstanding contribution to the development of methods for the calculation of transonic flow over real aircraft configurations. In 1991 he was elected a Fellow of the American Institute of Aeronautics and Astronautics, and he was also elected an Honorary Fellow of Trinity Hall, Cambridge. In 1993, he was selected to receive the American Institute of Aeronautics and Astronautics Fluid Dynamics Award in recognition of numerous contributions to computational fluid dynamics and the development of many widely used computer programs which have immeasurably improved the capability to analyze and understand complex flows. In 1995 he was elected a Fellow of the Royal Society of London for Improving Natural Knowledge. In 1995, he was selected by ASME to receive The Spirit of St. Louis Medal for numerous outstanding contributions to computational fluid dynamics and the development of many widely used computer programs that have immeasurably improved understanding of complex flow fields and become a dominant tool for aerodynamic design. In 1996 he was selected to receive the Theodorsen Lectureship Award from ICASE/NASA, Langley. In 1997 he was elected as a Foreign Associate to the National Academy of Engineering. In 2001 he recieved the degree Docteur Honoris Causa from the University of Paris, and in 2002 he recieved the degree Docteur Honoris Causa from Uppsala University. |
