- Construction of Ford Tri-Motor 14-AT Showing Center Hispano Suiza Engine, January 1932 - Ford Motor Company's Tri-Motor, built from 1926-1933, flew in many early American airline fleets. The all-metal airplane was rugged, dependable, and equally adaptable to passenger and freight service. Tri-Motors were built with some of the same mass production techniques used in Ford's automobile plants. This version, the 14-AT, featured three Hispano-Suiza Engines. This photograph reveals the interior of the central engine.

- Engine Designed by Glenn Curtiss for the Aerial Experiment Association's "Silver Dart" Airplane, 1908-1909 - In 1907, Alexander Graham Bell recruited a team of young aviation enthusiasts for his elite Aerial Experiment Association (AEA). The group produced a string of airplanes that ultimately achieved manned flight and contributed key developments to the fledgling field of aviation. AEA "motor expert" Glenn Curtiss designed this water-cooled engine to prevent overheating and allow for longer flights.

- Curtiss Model K-12 Engine and Model 18-B Airplane, circa 1919 - Glenn Curtiss established what would become the Curtiss Aeroplane and Motor Company in 1909. The company achieved success -- especially as military orders soared during World War I -- but Curtiss also endured failure. The promising 400-horsepower K-12 engine (pictured here, left) ultimately proved to be unreliable, and the model 18-B airplane (right) was never put into production.

- Liberty Aircraft Engine Cylinders, circa 1918 - Ford, Buick, Cadillac, Lincoln, Marmon, and Packard built more than 20,000 Liberty V-12 aircraft engines for the Allied Powers during World War I. Ford produced the engine cylinders for all manufacturers. The company developed a new method for making cylinders from steel tubing rather than boring them from solid forgings. These examples contrast Ford's process with a forged cylinder.

- Mary E. Von Mach Inspects Pratt & Whitney Engines While Working at the Willow Run Bomber Plant, November 30, 1942 - Mary E. Von Mach was Michigan's first licensed female pilot, earning her certificate in 1929. During World War II, Von Mach oversaw final inspection of the Pratt & Whitney engines installed in B-24 bomber airplanes at Ford's Willow Run plant. She was a charter member of the Ninety-Nines, an international organization that supported the work of women in aviation.

- Model of a Pratt & Whitney J-57 Turbojet Engine, circa 1958 - Pratt & Whitney introduced its J-57 turbojet engine in 1950. The versatile unit powered everything from Boeing 707 passenger airliners to B-52 bombers. Turbojets heat compressed air inside a gas turbine -- the turbine drives the compressor -- and expand the exhaust through a propelling nozzle, which provides thrust for the airplane. This electric-powered cutaway model illustrates the turbojet's operation.

- Pratt & Whitney Aircraft Engine Components, August 1943 - During World War II, Ford Motor Company manufactured Pratt & Whitney R-2800 aircraft engines using the same mass-production techniques developed for automobiles. Each 18-cylinder engine generated 2,000 horsepower. By August 1944, Ford assembled more than 2,400 engines a month in a special facility at the Rouge. Ford workers built nearly 58,000 engines by war's end.
