TUTORS Dr Karl Friedrich Doherr Dr Doherr retired from the DLR Institute of Flight Mechanics in 1998, where he was Head of the Mathematical Methods and Data Handling Branch. He had previously been an engineer within the DLR Recovery Systems Branch ultimately becoming Group Leader. Dr Doherr has lectured on the AIAA Parachute Short Course since 1987 on parachute flight dynamics. He was awarded the DFVLR Flight Mechanics Award in 1982, the AIAA Aerodynamic Decelerator Systems Technology Award in 1993 and the DGLR "Ehrennadel der Deutschen Luftfahrt" (Honory Pin of the German Aeronautics) in 1996. He is an Associate Fellow of the AIAA. Dr Doherr obtained his first degree at Technische Universität Braunschweig in 1965 and his PhD at the Technische Universität München in 1981 on Theoretical-experimental investigation of the dynamic behavior of parachute-payload systems in the wind tunnel. Dr Steve Lingard Steve Lingard is the Technical Director of Vorticity Ltd. He obtained BSc and PhD degrees in Aeronautical Engineering at the University of Bristol. After graduating he worked initially at RAE Farnborough on parachute unsteady aerodynamics and aircraft dynamics. Subsequently he moved to GQ Parachutes Ltd, where he became Technical Director and led the development of a large range of parachute systems. Steve joined Martin-Baker in 1990 to head their Systems Engineering Department. At Martin-Baker in addition to leading the systems engineering effort for all ejection seat programs, including Eurofighter and Joint Strike Fighter he established the Martin-Baker Space Systems department and was program manager and chief engineer for the Huygens interplanetary probe Descent Control Sub-System. Steve founded Vorticity in 2001 and has and has been successful in attracting extensive business from both the US and European Space industries including studies on probes for Mercury, Venus, Earth return, Mars and Europa, aerocapture at Titan and Mars, inflatable decelerator systems, and descent and landing systems for Mars missions. Steve has extensive experience in program and business management, theoretical and experimental aerodynamics, dynamics and aerospace systems engineering. He has been a Member of Faculty, AIAA / University of Minnesota Parachute Systems Technology Short Course since 1989, teaching steady aerodynamics, unsteady aerodynamics, gliding parachutes, supersonic parachutes, and parachutes for space use. He was awarded the AIAA Theodor Knacke Aerodynamic Decelerator Systems Award in 1997 and has published over 20 papers related to extra-terrestrial probes and decelerator systems. Dr Ralph Lorenz Dr Ralph Lorenz has a B.Eng. in Aerospace Systems Engineering from Southampton (UK). He worked for ESA/ESTEC (NL) during the design phase of the Huygens project and during his Ph.D. research Physics at the University of Kent (UK) he designed and built the penetrometer for Huygens' Surface Science Package. Since 1994 he has worked as a planetary scientist at the 3
Lunar and Planetary Lab, University of Arizona (USA) where his interests include in-situ exploration vehicles such as probes and penetrators, vehicle dynamics, planetary surfaces and climate, and nonequilibrium thermodynamics. He is author of over 90 papers in the refereed literature, and co-author of the books 'Lifting Titan's Veil' and 'Space Systems Failures. Dr. Dean Wolf Dean Wolf, retired from Sandia National Laboratories as a distinguished member of the technical staff after over 26 years of experience in analysis of nuclear weapon parachutes. He has a total of over forty-three years of engineering experience in aerodynamics and flight mechanics. While at Sandia he was involved in parachute systems work for the space shuttle solid rocket booster and orbiter, the Pioneer and Galileo landers, and the X-38. Before coming to Sandia, Dr. Wolf was also employed in similar areas by Northrop Grumman and General Dynamics. Currently, as a consultant, he has most recently worked in aerodynamics and flight mechanics of parachute systems and the application of analysis methods to the design, development and testing of these systems. Other recent experience has been in aerodynamics, aerodynamic heating and flight mechanics of foreign missile and other weapon systems. He has been a member of faculty of the AIAA Parachute Short Course for many years and was awarded the AIAA Theodor Knacke Aerodynamic Decelerator Systems Award in 1999. Dr. Wolf earned his Ph.D. in Applied Mechanics and his M.S. in Mechanical Engineering both from the University of Rhode Island and his B.S. in Aerospace Engineering from Iowa State University. Mr. John Underwood John Underwood is the Principal Engineer at Vorticity Ltd. He obtained his MA in Engineering at the University of Cambridge. After graduating he worked initially at Royal Ordnance on numerical simulations of weapons systems. Subsequently he moved to Martin-Baker where he performed analysis of ejection seat systems and managed wind tunnel test campaigns. While at Martin-Baker he was responsible for the system analysis of the Huygens Descent Control Sub-System (DCSS), supervision of the parachute wind tunnel testing, analysis of all parachute test results and ensuring the Huygens system test provided sufficient data to validate the DCSS. Since moving to Vorticity in 2003 John has continued to work on the Huygens mission through the delta-far and post-flight analysis. He has also worked on studies on probes for Mercury, Venus, Earth return, Mars and Titan. 4
