Ioan Vlădea (24 October 1907, Râșnov, 24 November 1976, Timișoara) was a Romanians, Romanian engineer from Industria Aeronautică Română, IAR Brașov, who developed the Gas compressor, compressor of airplane, plane engine IAR 80. After World War II he served as professor at Polytechnic University of Timișoara. He is considered the founder of Timișoara school of thermal engineering.

Early years and education

He was born in Râșnov, as the only son among the five children of Ioan and Elena Vlădea, a poor peasant family.De Sabata, p. 238 He attended the Facultatea de Electromecanică of Universitatea Politehnica of Timișoara, and graduated in 1931. He had as professors Victor Vâlcovici, Valeriu Alaci, Plautius Andronescu, Pompiliu Nicolau, Victor Vlad and Marin Bănărescu.De Sabata, p. 239 On 23 February 1931 received his engineering diploma titled ''Alimentarea cu energie electrică a orașului Brașov'' (Power supply of Brașov city), under the guidance of Dimitrie Leonida.De Sabata, p. 240 Then he gets a scholarship in aerodynamics, 1 March 1932''100 de ani de la nașterea profesorului Ioan Vlădea, fondatorul școlii timișorene de termotehnică''
, ''Univers Ingineresc'', retrieved 2010-04-13 at „Technische Hochschule Aachen” from Aachen, where on 21 July 1933De Sabata, p. 241 he sustains dissertation under the guidance of Hermann Starke (1874–1960) titled ''Über den Einfluss des Rumpfes (Gondeln) auf einige aerodynamische Eigenschaften des Flügels'' , thesis published in Sibiu in 1934 by author and also in „Bulletin Scientifique de l'École Politehnique de Timișoara” (1938).

At IAR Brașov

From 15 October 1933 he worked at Industria Aeronautică Română Brașov, until 10 December 1944. Until 31 August 1935 worked as designer of wing cells, guided by Elie Carafoli. In this period he designs several types of propeller (aircraft), propellers.

Didactic career

In October 1945 Marin Bănărescu invites Vlădea to teach at Politehnica of Timișoara the course „Motoare Ușoare” (plane engines). In March 1946 he passed the exam of lecturer at discipline „Mașini termice”. He commutes between Brașov–Timișoara. On 8 December 1948 he is appointed professor and head of Department of Thermal engineering newly founded by division of former Department of Termotehnică și Mașini Termice, whose head was Marin Bănărescu, position held until retirement, on 30 September 1973.De Sabata, p. 243 As recognition of merits, in 1970 he was awarded the title of Emeritus, Professor universitar emerit. After retirement he remains consulting professor, guiding PhDs like that of Sabin Peculea concerning heavy water.De Sabata, p. 244

Engineering achievements
