The Langley Aerodrome is a pioneering but unsuccessful manned, tandem wing-configuration powered flying machine, designed at the close of the 19th century by Smithsonian Institution Secretary Samuel Langley. The U.S. Army paid $50,000 for the project in 1898 after Langley's successful flights with small-scale unmanned models two years earlier.
The first bolometers made by Langley consisted of two steel, platinum, or palladium foil strips covered with lampblack. [ 4 ] [ 5 ] One strip was shielded from radiation and one exposed to it. The strips formed two branches of a Wheatstone bridge which was fitted with a sensitive galvanometer and connected to a battery.

Manly helped Smithsonian Institution Secretary Samuel Pierpont Langley build The Great Aerodrome, which was intended to be a manned, powered, winged flying machine. Manly made major contributions to the development of the aircraft's revolutionary 52 hp gasoline-fueled radial engine, called the Manly–Balzer engine. Manly attempted to pilot the ...
