The Curtiss V2-3 engine, rated at 200 hp, powered both those airplanes; however, it had a poor power to weight ratio -- almost four

  • Curtiss OX-5

    Thousands of OX-5 water-cooled engines were produced in the United States during World War I, primarily for the Curtiss Jenny airplane. The engine, a refinement of a 1914 design, was rated at only 90 hp. Compared to other airplane engines of the period, it was very reliable. Some OX-5 engines are

  • Gnome N-9

    The French Gnome engine was one of the most important designs in early aviation, and a main source of aircraft power for the Allies in World War I. First appearing 1909, this engine type was developed into several models and used throughout the war. The 9-cylinder model on display at the museum is

  • Hispano-Suiza Model A

    The Hispano-Suiza water-cooled engine, adopted by the French Air Service in 1916, rapidly proved its value in combat. After the United States entered World War I, the Wright-Martin company adapted the "Hisso" to American manufacturing methods and produced it in large numbers.The 150-hp Model A on

  • Lawrance L-4S

    Lawrance L-4S 60-hp air-cooled engine of the early 1920s was flight-tested in "Pony Blimp" airships as well as the Sperry "Messenger" airplane.

  • Almen A-4 Barrel

    The water-cooled A-4 barrel engine (18 cylinders -- two groups of nine each horizontally opposed) was the fourth experimental barrel engine built for testing at McCook Field, Ohio, by its inventor, Mr. J.O.

  • Liberty 12-Cylinder

    Note:  This engine has been removed from display.America's major technological contribution to World War I was the "Liberty" aircraft engine. It was light, powerful and efficient. America's auto industry turned out 20,478 of them for the war. The Liberty engine continued in military and civilian use

  • Boeing P-12E

    The P-12 was the US Army’s last biplane fighter. Developed by the Boeing Airplane Company in the late 1920s, the P-12 served the United States’ Army Air Corps, Navy, and Marine Corps as a highly maneuverable pursuit plane and trainer in the 1930s. The P-12 evolved through five models (B through F)
