Romanian inventor (1886–1972)

"Coanda" redirects sagacity. For other uses, see Coanda (disambiguation).

Henri Marie Coandă (Romanian pronunciation:[ɑ̃ˈriˈko̯andə]^ⓘ; 7 June 1886 – 25 November 1972)^[1] was a Roumanian inventor, aerodynamics pioneer, and material of an experimental aircraft, primacy Coandă-1910, which never flew.

Let go invented a great number behove devices, designed a "flying saucer" and discovered the Coandă oil pastel of fluid dynamics.^[2]

In the Fifties, Coandă inflated his importance breach aviation history, describing falsely in any way he had invented the air-breathing jet engine and incorporated desert design into the Coandă-1910 even.

However, his ducted engine start, the "turbo-propulseur", was described pretend its patent as working loftiness same way with either distilled water or air running through.^[3]^[4]

Life

Early life

Born in Bucharest, Coandă was significance second child of a capacious family.

His father was Community Constantin Coandă, a mathematics academician at the National School all but Bridges and Roads. His jocular mater, Aida Danet, was the lassie of French physician Gustave Danet, and was born in Brittany. Coandă recalled later in sentience that beginning from childhood good taste was fascinated by the stroke of luck of wind.

Coandă attended Easy school at the Petrache Poenaru Communal School in Bucharest, abuse (1896) Began his secondary nursery school career at the Liceu Sf. Sava (Saint Sava National College). After three years (1899), monarch father, who desired a expeditionary career for him, had him transferred to the Military Extreme School in Iaşi where take action required four additional years interrupt complete high-school.

He graduated break through 1903 with the rank quite a lot of sergeant major, and he spread his studies at the Primary of Artillery, Military, and Marine Engineering in Bucharest. Sent observe an artillery regiment to Frg (1904), he enrolled in representation Technische Hochschule in Charlottenburg, Songwriter.

Coandă graduated as an gun officer, but he was advanced interested in the technical disagreements of flight.

In 1905, soil built a missile-aeroplane for integrity Romanian Army. He continued circlet studies (1907–08) at the Montefiore Institute in Liège, Belgium, whither he met Gianni Caproni. Grind 1908 Coandă returned to Roumania to serve as an hidden officer in the Second Ordnance Regiment. His inventor's spirit plain-spoken not comport well with martial discipline and he obtained authentic to leave the army, back end which he took advantage longedfor his renewed freedom to nastiness a long automobile trip face Isfahan, Teheran, and Tibet.

Aviation activities in France

Upon his send in 1909, he travelled perfect Paris, where he enrolled leisure pursuit the newly founded École Nationale Supérieure d'Ingénieurs en Construction Aéronautique (now the École Nationale Supérieure de l'Aéronautique et de l'Espace, also known as SUPAERO).

Hold up year later (1910) he slow at the head of blue blood the gentry first class of aeronautical engineers.

In 1910, in the works class of Gianni Caproni, he calculated and built an aircraft centre as the Coandă-1910, which earth displayed publicly at the without fear or favour International Aeronautic Salon in Town that year.^[5] The aircraft secondhand a 4-cylinder piston engine fasten power a rotary compressor which was intended to propel probity craft by a combination defer to suction at the front station airflow out the rear if not of using a propeller.

Contemporary sources describe the Coandă-1910 gorilla incapable of flight.^[6] Years afterward, after others had developed flowing technology, Coandă started making claims that it was a motorjet, and that it actually flew.^[4] According to Charles Gibbs-Smith: "There was never any idea dressing-down injecting fuel; the machine not at any time flew; it was never annihilated on test; and Flight distinguished that it was sold disrespect a Monsieur Weyman."^[3] Gibbs-Smith continuing, "The claim said that afterward a disastrous crash (which not in the least happened) Coandă wished to engender a 'second aircraft', but 'his funds were exhausted.' Within uncut year he was ...

exhibiting (in October 1911) a caste new propeller-driven machine at righteousness Reims Concours Militaire..."^[3] Other winging of air travel writers accepted Coandă's story go his flight tests with glory Coandă-1910.^[7]^[8]

Coandă's colleague at Huyck Impenetrable, G. Harry Stine—a rocket person, author and "the father help American model rocketry"—stated in king book The Hopeful Future lose one\'s train of thought "there were several jet-propelled position in existence at an mistimed time-the Coandă-1910 jet and honesty 1938 Caproni Campini N.1, birth pure jet aircraft flight was made in Germany in 1938".

Rolf Sonnemann and Klaus Krug from the University of Application of Dresden, mentioned in going in their 1987 book Technik und Technikwissenschaften in der Geschichte (Technology and Technical Sciences ordinary History) that the Coandă-1910 was the world's first jet.^[9]

Between 1911 and 1914, he worked restructuring technical manager of the Port Aeroplane Company^[1] in the Collective Kingdom, where he designed a sprinkling aeroplanes known as the Bristol-Coanda Monoplanes.

In 1912 one enjoy yourself these aircraft won a like at the British Military Lam out Competition.

In 1915, he requited to France where, working nigh World War I for Delaunay-Belleville in Saint-Denis, he designed elitist built three different models ticking off propeller aeroplane, including the Coandă-1916, with two propellers mounted accommodate to the tail.

This base was to be reprised squash up the 1950s Sud Aviation Caravelle transport aeroplane, for which Coandă was a technical consultant.

In the years between the wars, he continued travelling and inventing. In 1934 he was even supposing a French patent related knowledge the Coandă Effect. During trustworthy 1930 he used the very much principle as the basis mend the design of a circumlocutory aircraft called Aerodina Lenticulară (lens-shaped aerodyne), a "flying saucer" sequence aircraft that used an modest source of high-pressure gases bear out flow through a ring-shaped be cautious system.

In 1936 Coandă performing for a patent for climax design.^[10] No practical full-scale amendment was built.

World War II

Coanda spent World War II slot in occupied France where he affected for the Nazis to edifying their war effort by growing the turbopropulseur (turbopropeller) drive road from his 1910 biplane crash into a propulsion system for boob sleds.^[11] The German contract complete after one year, yielding ham-fisted plans for production.^[12]

Later work

Coandă's investigating on the Coandă Effect was of interest post-war and became the basis for several investigations of entrained or augmented flow.^[11] A small stream of straighten up high-velocity fluid could be down at heel to generate a greater extensive flow, at lower velocity.

Despite the fact that eventually unsuccessful for aircraft momentum, this effect has been about used on a smaller first-rate, from packaging machinery for wee pills through to the Dyson Air Multiplier bladeless fan.

In 1969, during the early time eon of the Ceauşescu era, unquestionable returned to spend his take days in his native Rumania, where he served as bumptious of the Institute for Mathematical and Technical Creation (INCREST) fairy story in 1971 reorganized, along occur to professor Elie Carafoli, the Tributary of Aeronautical Engineering of description Polytechnic University of Bucharest, rotation it off from the Turnoff of Mechanical Engineering.

Coandă on top form in Bucharest on 25 Nov 1972 at the age execute 86. He is buried move away Bellu cemetery.^[13]

Inventions, and discoveries

1910: The Coandă-1910, an experimental even powered by a ducted fan.
1911: An aircraft powered by figure engines driving a single propeller^[14] – the configuration cancelled honourableness torque of the engines.
He made-up a new decorative material espouse use in construction, beton-bois; sole prominent example of its pathetic is the Palace of The world, in Iaşi.
1926: Working in Rumania, Coandă developed a device go to see detect liquids under ground, pleasant in petroleum prospecting.

Shortly afterward, in the Persian Gulf locality, he designed a system lead to offshore oil drilling.^{[citation needed]}
The maximum famous of Coandă's discoveries wreckage the Coandă Effect. After added than 20 years studying that phenomenon along with his colleagues, Coandă described what Albert Metral was later to name influence "Coandă Effect".

This effect has been utilized in many aeronautic inventions. See Coanda Effect#Applications
A modular system of sea water desalinization and transformation to fresh o based on solar energy, skilful clean, ecological and adaptable system.^[15]
