The Lanchester Lecture was set up to honour Frederick William Lanchester, HonFRAeS, Britain’s first great aerodynamicist. He is best known for designing and building the first British petrol driven four wheeled motor car (in 1895) and for his work on the theory of fl ight and design of aircraft. Lanchester’s work on stability was fundamental to aviation and he formulated the first comprehensive theory of lift and drag. This lecture recognises the background and distinguished work of Frederick William Lanchester, and notes that Dr John E Lamar’s background has similarities with his, especially parts of his research in aeronautics and vortices. John’s work spans the time-frame from America’s Super Sonic Transport through 2009. An early emphasis involved wind-tunnel testing of research aircraft models and the development of computer codes for subsonic aerodynamics of wing planforms. These attached-flow codes were applied to various configurations, including those with variablesweep, dihedral, and more than one planform in both the analysis - and design-modes. These codes were used to provide a connection between leading-edge-forces and the associated additional lift on delta-wings with shed-vortex systems through the leading-edge suction analogy of Edward C. Polhamus. Subsequently, John extended the suction analogy to configurations with side-edges to predict the vortical-flow aerodynamics on complex configurations, including wing-strake combinations. These analysis codes could also be used in a design-by-analysis mode for configurations with leading-edge shed vortices. Later, he was involved in vortical-flow flight research with the F-106B and the F-16XL aircraft at cruise and maneuver conditions. Associated CFD predictions, generated by me and other members of the RTO/AVT-113 task group, have increased our understanding of the flight flow-physics measured on the F-16XL aircraft. 

About the speaker: Dr John Lamar, Lamar Engineering Consultanship

Dr John E Lamar holds a BS and a MS in Aeronautical Engineering from the University of Alabama as well as a PhD from Virginia Tech. He has authored or co-authored over 110 papers and is an Associate Fellow of the AIAA. John began his career at NASA Langley Research Center in 1963 where he performed numerous duties including the Von Karman Lecturer, the Principal Investigator in three flight projects on the F-106B and F-16XL and has performed analytical, computational and experimental (wind-tunnel and fl ight) fluid dynamics. In 1983, John received the AIAA Aerodynamics Award and in 1989-1990 was the National Space Club’s Dr Hugh L Dryden Memorial Fellow. In addition, he Co-Chaired RTO/AVT-113, a part of the scientifi c arm of NATO from 2003-2008. John retired from NASA Langley in January 2006 to establish his engineering consulting company but was the Distinguished Research Associate until 2009. Both during his time, and NASA and since, he has lectured at various universities, companies and governmental research laboratories in USA & Europe. In 2009, John jointly shared the AIAA International Cooperation Award with Prof Hummel.
