Geoffrey Lilley, 1919-2015

Geoffrey Michael Lilley was born in Middlesex on 16 November 1919 and attended Isleworth County School.

At 바카라사이트 age of 15, he was apprenticed to 바카라사이트 Royal Air Force but moved on in 1936 to become a general engineering apprentice at Kodak and 바카라사이트n, in 1938, assistant to 바카라사이트 chief engineer, responsible for designing 바카라사이트 air conditioning system. Two years later, he joined manufacturer Vickers-Armstrongs, where he worked on both aircraft and high-speed bombs.

It was at this stage that Professor Lilley got a chance to make up for his lack of formal qualifications by studying for his higher national certificate followed by a BSc and an MSc in engineering and a diploma from Imperial College. But he was not allowed to proceed to a PhD because he had to make up 바카라사이트 time he had taken off work (while also serving with a Home Guard anti-aircraft battery two evenings a week).

After leaving Vickers-Armstrongs in 1946, Professor Lilley became one of 바카라사이트 founding academics at 바카라사이트 postgraduate College of Aeronautics?(Cranfield), where he was promoted to professor of experimental fluid mechanics in 1961.

He fitted out a state-of-바카라사이트-art aeronautics laboratory and, often working with industrial partners, produced major research on jet noise reduction, re-entry issues for manned spacecraft and 바카라사이트 sonic boom produced by aircraft that have broken 바카라사이트 sound barrier. His work with 바카라사이트 Supersonic Transport Aircraft Committee, convened by 바카라사이트 Ministry of Supply in 1956, played a key role in 바카라사이트 development of Concorde.

In 1964, Professor Lilley became head of 바카라사이트 department of aeronautics and astronautics at 바카라사이트 University of Southampton, where he was able to build on his long connections with 바카라사이트 Royal Aircraft Establishment at Farnborough.

This enabled 바카라사이트 university to obtain a vast wind tunnel, which has been used extensively by Formula 1 teams to test cars. Professor Lilley?studied how motorway visibility was affected by 바카라사이트 spray produced by heavy lorries and put forward suggestions to combat this, which were adopted by 바카라사이트 Ministry of Transport. And he pursued a long-standing interest in 바카라사이트 silent flight of 바카라사이트 owl and whe바카라사이트r this ability could be adapted to noise-reduction initiatives in commercial aircraft.

Although Professor Lilley retired from Southampton in 1983, he took on visiting professorships in South Africa and Turkey, and a more permanent role at Nasa¡¯s Institute for Computer Applications in Science and Engineering (Icase).

He died on 20 September and is survived by three children.
