The Engines of Pratt & Whitney: A Technical History recounts the role played by Pratt & Whitney (P&W) in the evolution of aircraft engines from 1925 to the present timefor the most part as told by the engineers who made the history. A technical reference of all P&W engines and their applications, the book describes the evolution of piston engines and gas turbines, and offers young engineers a wealth of insights about design, development, marketing, and product support efforts for customers at home and abroad. The first three chapters introduce the contributions of Frederick Rentschler, George Mead, and Leonard Hobbs, with stories of how each new piston engine came into being. From 19401945 P&W committed its engineering efforts to winning World War II, but when the war was over, P&W found itself on the outside of the gas turbine market, which was capably being served by General Electric and Westinghouse. How P&W emerged from being five years behind the competition in 1945 to a positio
The Rolls-Royce Merlin liquid-cooled V-12 piston aero engine is considered an icon of British engineering with a worldwide recognition. It was one of the most successful aircraft engines of the Second World War period and its incremental development ran hand in hand with that of the legendary Supermarine Spitfire to which it was fitted from the very beginning. From its genesis in the 740hp PV-12 engine that was first flown in 1935, the Merlin went through rapid development during the war years until in its ultimate version, the Merlin 130 series designed specifically for the de Havilland Hornet, it produced over 2,600hp.
Merlin engines powered many more of the best-known Allied combat aircraft of the war including the Hawker Hurricane, Boulton Paul Defiant, P-51 Mustang, Avro Lancaster, Handley Page Halifax, and the de Havilland Mosquito.
