Samuel Pierpont Langley (August 22, 1834 – February 27, 1906) was an American aviation pioneer, astronomer and physicist who invented the bolometer. He was the third secretary of the Smithsonian Institution and a professor of astronomy at the University of Pittsburgh , where he was the director of the Allegheny Observatory .
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. [1]
The Langley Gold Medal, or Samuel P. Langley Medal for Aerodromics, is an award given by the Smithsonian Institution for outstanding contributions to the sciences of aeronautics and astronautics. Named in honor of Samuel P. Langley, the Smithsonian's third Secretary, it was authorized by the Board of Regents in 1909. [1]
Power, P, from an incident signal is absorbed and heats up a thermal mass with heat capacity, C, and temperature, T. The thermal mass is connected to a reservoir of constant temperature through a link with thermal conductance, G. The temperature increase is ΔT = P/G and is measured with a resistive thermometer, allowing the determination of P.
Assisted S.P. Langley (May – Nov 1895); [111] test pilot for Octave Chanute; [112] designed the Herring regulator; designed and constructed a compressed-air motorized biplane and reported a 15-meter hop (10 Oct 1898) and a 22-meter hop (12 Oct 1898); [113] business partners with Glenn Curtiss (1909).

1896: Samuel Pierpont Langley successfully flew unpiloted steam-powered models. [2] 1897: Carl Richard Nyberg's Flugan developed steam-powered aircraft over a period from 1897 to 1922, but they never achieved more than a few short hops. 1899: Gustave Whitehead built, and was purported to have flown, a steam-powered airplane in Pittsburgh ...
