elektronika: Coandă effect

Evidence: 100 • authority: 72

The Coandă effect ( or ) is the tendency of a fluid jet to stay attached to a surface of any form. Merriam-Webster describes it as "the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops." It is named after Romanian inventor Henri Coandă, who was the first to recognize the practical application of the phenomenon in aircraft design around 1910. It was first documented explicitly in two patents issued in 1936.

A hovercraft (pl.: also hovercraft), also known as an air-cushion vehicle or ACV, is an amphibious craft capable of travelling over land, water, mud, ice, and various other surfaces. Hovercraft use blowers to produce a large volume of air below the hull, or air cushion, that is slightly above atmospheric pressure. The pressure difference between the higher-pressure air below the hull and lower pressure ambient air above it produces lift, which causes the hull to float above the running surface. For stability reasons, the air is typically blown through slots or holes around the outside of a disk- or oval-shaped platform, giving most hovercraft a characteristic rounded-rectangle shape. The fi…

The Institut Supérieur de l'Aéronautique et de l'Espace (French pronunciation: [ɛ̃stity sypeʁjœʁ də laeʁɔnotik e də lɛspas], ISAE-SUPAERO; lit. 'Higher Institute of Aeronautics and Space') is a French grande école of engineering, founded in 1909. It is the world's first dedicated institute of aerospace engineering. ISAE-SUPAERO is part of University of Toulouse, ISSAT, PEGASUS, GEA, Toulouse Tech, CESAER and Aerospace Valley. The institute is ranked highly among Europe's engineering schools. Historically ISAE-SUPAERO resulted from the merger between SUPAERO and ENSICA in the summer of 2007. The aim of this move was to increase the international visibility of SUPAERO and the ENSICA (both of…

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. The unusual aircraft attracted attention at the Second International Aeronautical Exhibition in Paris in October 1910, being the only exhibit without a propeller, but the aircraft was not displayed afterwards, and it fell from public awareness. Coandă used a similar turbo-propulseur to drive a snow sledge, but he did not develop it further for aircraft. Decades later, after the practical d…

Henri Marie Coandă (Romanian pronunciation: [ɑ̃ˈri ˈko̯andə] ; 7 June 1886 – 25 November 1972) 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 dynamics. In the 1950s, Coandă inflated his importance in aviation history, describing falsely how he had invented the air-breathing jet engine and incorporated that design into the Coandă-1910 aircraft. However, his ducted engine design, the "turbo-propulseur", was described in its patent as working the same way with either water or air running through.
