\nObr. Henri Coanda (Henri Coand\u0103) 6.7.1886 – Bukure\u0161\u0165, Rumunsko, 25.11.1972 Bukure\u0161\u0165, Rumunsko<\/em><\/p>\n

24 let\u00fd Rumun Henri Coanda vystavil na pa\u0159\u00ed\u017esk\u00e9m aerosal\u00f3nu na po\u010d\u00e1tku \u0159\u00edjna 1910 ji\u017e tehdy velmi neobvykl\u00e9 letadlo.<\/p>\n

Letadlo m\u011blo tehdy opravdu proudov\u00fd motor. Av\u0161ak m\u00edsto dne\u0161n\u00ed turb\u00edny, kter\u00e1 p\u0159em\u011b\u0148uje energii plynu na rota\u010dn\u00ed pohyb kompresoru, v Coandov\u011b letounu byl norm\u00e1ln\u00ed motor o s\u00edle 50 ko\u0148sk\u00fdch sil. Ten poh\u00e1n\u011bl kompresor, \u017eenouc\u00ed do spalovac\u00ed komory velk\u00e9 masy vzduchu.<\/p>\n

Letadlo uskute\u010dnilo sv\u016fj prvn\u00ed a z\u00e1rove\u0148 posledn\u00ed let v \u0159\u00edjnu 1910, za obrovsk\u00e9ho z\u00e1jmu ve\u0159ejnosti. U kormidla byl s\u00e1m konstrukt\u00e9r. Pro ochranu ocasu p\u0159ed plameny z motoru Coanda instaloval na letadlo deflektory.<\/p>\n

B\u011bhem letu se uk\u00e1zalo, \u017ee um\u00edst\u011bn\u00ed je chybn\u00e9. Deflektory neodklonily plamen z motoru \u00fapln\u011b, a ocas letadla sho\u0159el. Pilot nad strojem ztratil kontrolu a ten narazil do stodoly. Coanda vypadl z kabiny a byl v\u00e1\u017en\u011b zran\u011bn.<\/p>\n

Coanda cht\u011bl uk\u00e1zat, \u017ee vrtule d\u0159\u00edve \u010di pozd\u011bji ustoup\u00ed proudov\u00e9mu motoru. Talentovan\u00fd rumunsk\u00fd in\u017een\u00fdr odvrhl vrtuli p\u0159\u00edli\u0161 brzy. Vrtule je\u0161t\u011b n\u011bkolik des\u00edtek let poh\u00e1n\u011bla letadla v\u0161ech typ\u016f a pou\u017e\u00edv\u00e1 se dodnes.<\/p>\n

Dal\u0161\u00ed v\u00fdvoj t\u00e9to koncepce nastal a\u017e po t\u00e9m\u011b\u0159 30 letech v N\u011bmecku, kdy\u017e vznikl proudov\u00fd letoun Heinkel He 178.<\/p>\n
