Engine Design Trends—I: A Paper Delivered at the Eighth Aircraft Production Conference Organized By the Institution of Production Engineers and Held at the College of Aeronautics, Cranfield, on April 5–7, 1962

IN this Paper an endeavour is made to indicate the way in which design has progressed from the complex military piston engine, through the elegant simplicity of a new prime mover and then, as technical progress showed how it could be improved, on to the complex modern gas turbine engine.
