The Merlin: The Engine That Won the Second World War

El Rolls-Royce Merlin es uno de los motores de avión más famosos de la historia. Impulsó aviones clave de la Segunda Guerra Mundial, como el Spitfire y el Hurricane, que defendieron Gran Bretaña durante la Batalla de Inglaterra en 1940. También fue utilizado en los bombarderos Lancaster y Halifax en misiones sobre Alemania, así como en el Mosquito, conocido por su precisión en bombardeos y reconocimiento.
En Estados Unidos, el Merlin equipó al P-51 Mustang, que escoltaba a los bombarderos B-17 y B-29 en incursiones diurnas. El Mustang también operó en el norte de África, el Mediterráneo y el Pacífico. Este motor fue clave en la victoria aliada.
El Merlin sigue siendo un símbolo y su característico sonido aún se escucha en Inglaterra, especialmente en exhibiciones del Battle o Britain Memorial Flight. Recientemente apareció en la celebración del centenario de la RAF, con un Lancaster liderando una formación de Spitfires y Hurricanes.
El expiloto Gordon Wilson narra el desarrollo y uso de este motor en la guerra, incluyendo relatos de las tripulaciones que dependían de él.

Vee's for Victory! - The Story of the Allison V-1710 Aircraft Engine, 1929-1948

Over 60 percent of U.S. Army fighters during World War II were powered by the Allison V-1710 engine, including the P-38, P-39, the lightweight fighters XP-46A and XP-47, as well as the early P-51 Mustangs.
It was a strong and reliable power plant that powered the pre-war generation of 400 mph Army pursuits, and the majority of Army combat fighters on through World War II. Even so, the V-1710 was controversial and often maligned, considered by some to have been a "second-rate" engine. Author Whitney's objective was to find, and tell, the true story of the 70,000 V-1710's and the people who built them.

A Technical and Operational History of the Liberty Engine - Tanks, Ships and Aircraft 1917-1960

The aim of the Liberty was to standardize aircraft engine design. The theory was to have an engine design that could be built in several sizes and thus power airplanes for any purpose, from training to bombing. The differences in sizes would be obtained by using different numbers of cylinders in the same design. A large number of other parts would also be used in common by all resulting sizes of the engine series.

The initial concept called for four-, six-, eight-, and 12-cylinder models. An X-24 version was built experimentally, and one- and two-cylinder models were built for testing purposes.
The engine design eventually saw use on land, sea, and in the air, and its active military career spanned the years 1917 to 1960. In addition, it provided noble service in a multitude of civilian uses, and still does even today, some 90 years after the first engine ran.

This book covers the complete history of the Liberty's design, production, and use in amazing detail and includes appendixes covering contracts, testing, specifications, and much more.

The Engines of Pratt & Whitney - A Technical History as Told by the Engineers Who Made the History

Describes the evolution from piston engines to gas turbines by the engineers who created those engines. Included are hundreds of archival photographs, as well as over a dozen tables listing specifications and applications. The story starts with the founding of the company in the 1920s to provide reliable air-cooled piston engines to the military and to help create coast-to-coast commercial flight service.
Pratt & Whitney quickly dominated commercial and military flight in the 1930s, ultimately providing half the horsepower of American engines during World War II.

Jack Connors explains how Pratt & Whitney came from behind the competition in developing gas turbines after the war with the debut of the J57, which powered the B-52 in 1952 and later the Air Force Century Series fighters (F-100, F-101, and F-102) and the Navy A-3D, F-4D, and F-8 airplanes.
Also covered is the development of the J58, which powered the Mach 3+ YF-12 and SR-71 aircraft and subsequent military engines; the F100 in the F-15 and F-16; the F119 in the F-22; and, the F135 in the F-35 series.Pratt & Whitney's contribution to the luxury commercial jet era travel is also detailed, with its JT3, JT3D, JT4, JT8D, JT9D, PW2000, PW4000, and PW6000 in Boeing, Douglas, and Airbus aircraft.

This history of Pratt & Whitney's role in the evolution of aircraft engines from 1925 to the present day offers young engineers a wealth of insights about design, development, marketing, and product support for commercial and military customers.

Sunbeam Aero Engines

La Sunbeam Motor Car Company, el primer gran fabricante británico de motores de aviones, entró en la industria de la aviación en 1912. Fueron de los primeros en comprar un avión para probar sus motores, pilotado por el famoso piloto de pruebas Jack Alcock.

Durante la Primera Guerra Mundial, Sunbeam fue un proveedor crucial de motores y aviones, especialmente para el Royal Naval Air Service. Los motores Sunbeam eran los motores británicos más potentes de la época. Impulsaron el primer avión en torpedear un barco enemigo, el único avión en volar en la Batalla de Jutlandia, y los primeros hidroaviones en operar en África central.

Después de la guerra, los motores Sunbeam impulsaron dirigibles británicos notables como el R.34, el primer avión en cruzar el Atlántico de este a oeste y hacer una doble travesía, y el R.33, el dirigible británico con más horas de vuelo.

Cuando Sunbeam volvió a la fabricación de automóviles, sus motores de avión se utilizaron en coches que batieron récords de velocidad, incluidos los primeros en superar las 150 mph y 200 mph, irónicamente más rápidos que cualquier avión propulsado por Sunbeam.
