Preface GAS TURBINE THEORY 5TH EDITION:
This edition has been written to mark the 50th anniversary of the original publication of Gas Turbine Theory in 1951. The gas turbine was in its infancy when Cohen and Rogers laid the foundation of the basic theory of this new prime mover, including cycle design, aerodynamics and thermodynamics of the individual components·and off-design performance. Fifty years later the layout of the book is essentially the same, but it has been greatly expanded to cover the continued development and widely increasing applications of the gas turbine.
In 1951 the gas turbine had a very limited role, primarily as a military jet engine with a 'big' engine having a thrust of about 15 kN. There were no civil aircraft applications and only a handful of experimental industrial engines had been built; these could not compete successfully against the established diesel engine and steam turbine.
In the last fifty years the gas turbine has had an enormous impact, starting with the introduction of
commercial jet transports in the early 1950s; this led directly to the demise of oceanic passenger liners and trans-continental trains in North America.
The application of gas turbines has resulted in a revolutionary growth in the gas pipeline industry and, more recently, has had a similar impact on electric power generation. Industrial gas turbines are now approaching unit sizes of 300 MW and thermal efficiencies in excess of 40 per cent, while combined gas and steam cycles achieve efficiencies of close to 60 per cent.
The beginning of the 21st century may see the widespread use of the micro turbine in distributed power plants and also the combination of the gas turbine.with fuel cells.
The outstanding reliability of the gas turbine is clearly demonstrated by the large-scale use of twin-engined passenger aircraft on oceanic routes; with engines achieving as much as 40 000 hours without being removed from the wing.
