- Steam aircraft
Steam aircraft are
aircraft that are propelled bysteam engine s. They were unusual devices because of the difficulty in producing apowerplant with a high enoughpower to weight ratio to be practical. They are distinct fromairship s that use steam as their lifting gas which are known asthermal airship s.History
*1842: The
Aerial Steam Carriage ofWilliam Samuel Henson andJohn Stringfellow was patented, but was never successful, although a steam-powered model was flown in 1848.
*1852:Henri Giffard flies a 3 horsepower (2 kW) steam-powered dirigible over Paris; it was the first powered aircraft.
*1874: Félix du Temple flies a steam powered aluminium Monoplane off a downhill run. While it did not achieve level flight, it was the first manned heavier-than-air powered flight.
*1894:Sir Hiram Stevens Maxim (inventor of theMaxim Gun ) built and tested a large steam powered aircraft. The machine generated sufficient lift and thrust to break free of the test track and fly but was never operated as a piloted aircraft.
*1902: Louis Gagnon flew a steam helicopter inRossland, British Columbia , called the "Flying Steam Shovel". Control problems caused a crash.
*1930s:George D. Besler andWilliam J. Besler 's prototype steam biplane, based on aTravel Air 2000 , flew several times at Oakland airport. It was powered by a two-cylinder, 150 hp reciprocating engine designed by the Doble Steam Motors Company and Besler weighing about 500 lbs [Citation | last = | first = | author-link = | last2 = | first2 = | author2-link = | title = Flight by Steam | newspaper =TIME | pages = | year = | date = April 24 1933 | url = http://www.time.com/time/magazine/article/0,9171,769820,00.html] and was capable ofSTOL operation due to the ease of reversing the thrust.

*1944: A steam-powered version of the Messerschmitt Me 264a was mooted but never constructed. This was to have been powered by asteam turbine developing over 6,000 horsepower and driving a 5.3 meter (17' 6") diameter propeller. The fuel would have been a mixture of powdered coal andpetroleum . The main advantages to this powerplant were considered to be constant power at all altitudes and simple maintenance.

*1960s: Some work was done by Don Johnson of Thermodynamic Systems Inc. Newport Beach, CA on creating a steam-powered helicopter using a steam engine of 150 horsepower installed in a Hughes 300 helicopter. The steam engine was a compact cylindrical double-acting uniflow [similar in layout to the Dyna-Cam Aero engine] built by Controlled Steam Dynamics, Inc.External links
