SUMMARY:The Fruit of a Miss-spent Youth: Gas Turbine Combustion from the 5

DESCRIPTION:The talk presents three examples of aircraft gas turbine combu
 stion research taken from the early years of a career spanning 45 years\, 
 before gas turbines became a commodity.\nEverything was an adventure. Comp
 uters were in their infancy. Correlations required for aerothermal design 
 were being created driven by urgent need. The new large fan engines of the
  1970s required radical innovations. Tubular combustors were abandoned and
  replaced by annular designs. Pressure jet fuel injectors were replaced by
  air assisted atomisers. The lack of design data gave rise to serious perf
 ormance problems which had to be solved by intensive development. \nAlongs
 ide the development of conventional combustion systems\, continuous and in
 termittent detonation driven systems and wave rotors were under investigat
 ion.\n\nThe three topics selected for this presentation are \n1.	Wave roto
 r research – 1966~1971\n2.	The development of the RB211 combustor  1970~
 1980\n3.	Investigation into engine fires resulting from intershaft bearing
  failures in the RB211  1980~1981.\n
