Henri Coandă - Wikipedia
Henri Marie Coandă (Romanian pronunciation: [ɑ̃ˈri ˈko̯andə] ⓘ; 7 June 1886 – 25 November 1972) [1] was a Romanian inventor, aerodynamics pioneer, and builder of an experimental aircraft, the Coandă-1910, which never flew. He invented a great number of devices, designed a "flying saucer" and discovered the Coandă effect of fluid ...
Coandă-1910 - Wikipedia
The Coandă-1910, designed by Romanian inventor Henri Coandă, was an unconventional sesquiplane aircraft powered by a ducted fan. Called the "turbo-propulseur" by Coandă, its experimental engine consisted of a conventional piston engine driving a multi-bladed centrifugal blower which exhausted into a duct.
Coandă effect - Wikipedia
The Coandă effect can be demonstrated by directing a small jet of air upwards at an angle over a ping pong ball. The jet is drawn to and follows the upper surface of the ball curving around it, due to the (radial) acceleration (slowing and turning) of the air around the ball.
Coanda’s Claim | Smithsonian
2010年12月6日 · The Motor (London) said the inventor claimed it “will be capable of 60 mph.” But no record has been found of an actual run. The Motor only concluded that the sled was to be sent to Russia.

2019年11月25日 · Coanda effects, if present at all, are only a secondary force if Viktor Schauberger’s calculations are correct. Coanda effects alone could never be powerful enough to generate the lifting force equal to 228 tons which Schauberger estimated …

利用 Coanda 效应，可以有意识地诱导空气气流，在机翼上表面产生比飞机和空气相对速度更大的气流速度，提高升力。 70 年代时，美国空军已经意识到 C-130 在速度、航程和载重上的局限，希望用喷气式中型战术运输机取代，这就是“先进中型短距起落运输机 ...

Coanda, however, missed his critical historic claim to fame while toying with the aircraft's primitive water-cooled 50 hp four-cylinder Clerget motor-driven thermal jet turbine which Coanda called a "Air-Reaction Engine". The motor was connected to a gearbox and then to a compressor which rotated at 4,000 rpm.

2019年3月18日 · The Coandă effect is the tendency of a stream of fluid (air or liquid) coming from an opening to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops. It can also be described as the tendency of a fluid to adhere to the walls of a convex surface.

2013年2月11日 · Some airplanes, such as the C-17 Globemaster III, use the Coanda effect to route exhaust across the tops of their wings to speed airflow, increasing lift when planes are flying at low speeds.
Coandă 1911 Monoplane - Old Machine Press
2015年5月23日 · Perhaps the most unusual feature of Coandă’s 1911 monoplane was its engine installation and propeller drive. At the front of the aircraft were two Gnome 7 Gamma rotary engines. The seven-cylinder engines had a 5.1 in (130 mm) bore, a 4.7 in (120 mm) stroke, and a total displacement of 680 cu in (11.1 L).
