Langley-Manly-Balzer Radial 5 Engine
Designed by Dr. Samuel Pierpont Langley, this engine powered his unsuccessful man-carrying airplane of 1903, known as the Langley Aerodrome A.
In its original form the engine was an 8 horsepower, air-cooled rotary designed and built by Stephen M. Balzer of New York City, N.Y.
After being redesigned and rebuilt as a water-cooled fixed radial by Charles M. Manly, Langley's assistant, it became the world’s most advanced aero engine for several years.
