This book explains in detailed, wellillustrated, and easytounderstand terms how these pistonpowered radialengine airliners advanced rapidly. The aircraft originated with fabriccovered fuselages with wooden wings and morphed into allmetal Ford Trimotors as the worlds first true  modern airliner,  the Douglas DC3, longrange fourengine transoceanic flying boats. Finally, the ultimate  Queens of the skies  Lockheed Constellations, Douglas DC7s, and Boeing Stratocruisers flew at the zenith of the piston age in the midtolate 1950s.Many magnificent aircraft bridged the gap from small singleengine airliners carrying six passengers in the 1920s to large longrange, fourengine landplanes carrying 60to80 passengers and linking all the worlds continents by air in the 1950s. This book not only traces the technical evolution of every radialengine powerplant used over that time span but also includes interesting and factfilled 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 3,500hp 28cylinder Pratt \u0026amp; Whitney R4360; it is one of 12 different radial engines covered indepth 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 pistonpowered airliners are interwoven with detailed yet easytounderstand descriptions and graphics showing the intricacies of highperformance piston radial engines. The advancement and success of America s air transportation system can be linked directly to the concurrent growth of longrange, highspeed airliners and their revolutionary powerplants, and this book tells the compelling story of aviation progress and development for the very first time.\u003c\/p\u003e","brand":"Specialty Press","offers":[{"title":"Default Title","offer_id":47335034061045,"sku":"SONG1580072577","price":47.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/5804\/8501\/files\/81Rj8_4G8bL.jpg?v=1763976665","url":"https:\/\/ergodebooks.com\/products\/america-s-roundengine-airliners-airframes-and-powerplants-in-the-golden-age-of-aviation","provider":"Ergodebooks","version":"1.0","type":"link"}
