JAMES L. BETTNER retired from Rolls-Royce Aero Engines in 2002, where he was the Program Manager for the AE 3007H engine, which is the propulsion system for the Air Force’s high-altitude, long-endurance Global Hawk unmanned aerial vehicle. Previously, he was the supervisor of the Preliminary Design Department, where he conducted studies on material properties in advanced engines, convertible engines, gearboxes for high-speed rotorcraft, wave rotors, and fuel-cooled engines. Dr. Bettner also directed ERAST studies of optimum propulsion systems for very-high-altitude research aircraft. He directed the preliminary design of a propulsion system for a large fan-in-wing Special Operations Force aircraft, where the engines powered a conventional fan in forward flight but were clutched to the fan-in-wing for vertical takeoff and landing. He directed the preliminary design analysis of developing a 2000-pound-thrust turbofan from the T800 turboshaft engine for a medium-altitude application. Prior to that, Dr. Bettner was a member of the propfan development team, which included the NASA-funded single-rotation propfan test assessment (PTA) and the company-funded counter-rotation PW-Allison 578 projects.

PAUL BEVILAQUA, NAE, is a Distinguished Professor in the Department of Mechanical and Aerospace Engineering at the University of Miami. Previously he was Manager of Advanced Development Programs at Lockheed Martin Aeronautics Company.

Consequently, his research has included study of the thermodynamics of energy conversion for propulsion systems, including turbojet engines, ramjets, and thrust augmenting ejectors. He has also investigated the development of turbulent jets and wakes, in order to understand the fundamental mechanisms of turbulent mixing and entrainment and the jet induced forces on aerodynamic surfaces. This has lead to interests in computer aided engineering and technical management, especially in applying the principles of lean manufacturing to engineering and design processes. He has also contributed to the technologies associated with the design and development of stealth aircraft.

EARL H. DOWELL, NAE, is William Holland Hall Professor and Dean Emeritus in the Edmund T. Pratt, Jr. School of Engineering at Duke University. The fundamental areas of Professor Dowell's research interests are dynamics, fluid and solid mechanics and acoustics. A particular focus at present is on the dynamics of nonlinear fluid and structural systems and their associated limit cycle and chaotic motions. Examples include flexible plates and shells excited by dynamic fluid forces, oscillating airfoils and wings in a transonic flow, and aero-mechanical instability of rotorcraft systems. Also of interest are studies of systems with many degrees-of-freedom. Three aspects of such systems are being considered: eigenfunctions of nonconservative (fluid or fluid-structure) systems, turbulence as a multi-mode chaotic phenomena, and the asymptotic behavior of a dynamical system as the number of degrees-of-freedom becomes very large (asymptotic model analysis). The potential applications for the results of these research efforts are very broad, but a principal emphasis is on aerospace, automotive, naval and other transportation.
