Many magnificent aircraft bridged the gap from small single-engine airliners carrying six passengers in the 1920s to large long-range, four-engine landplanes carrying 60-to-80 passengers and linking all the world's continents by air in the 1950s. This book not only traces the technical evolution of every radial-engine powerplant used over that time span but also includes interesting and fact-filled sidebars that detail what it was like flying aboard each generation of these aircraft. In 1948, the largest radial piston engine ever produced entered airline service, the mighty 3,500-hp 28-cylinder Pratt & Whitney R-4360; it is one of 12 different radial engines covered in-depth by the authors of this book.
With one author having been an airline pilot and the other an air racing enthusiast and lifetime member of the Aircraft Engine Historical Society, this book offers readers the best of both worlds. Colorfully illustrated stories of flying aboard the world's greatest piston-powered airliners are interwoven with detailed yet easy-to-understand descriptions and graphics showing the intricacies of high-performance piston radial engines. The advancement and success of America's air transportation system can be linked directly to the concurrent growth of long-range, high-speed airliners and their revolutionary powerplants, and this book tells the compelling story of aviation progress and development for the very first time.
