Nicolas Minorsky

Nicolas Minorsky (* September 24 1885 in Kortschewa, Tver, Russian Empire; † July 31, 1970 ) was an inventor of a gyro.

Career

Nicolas Minorsky studied at the Nautical School in Saint Petersburg and from 1908 at the Faculty of Electrical Engineering at the University of Nancy. He then worked at the Technical school of the Czar, until his PhD in the field of science in the year 1914. 1914 By 1917, he served in the Russian Navy. During this time he developed a gyro and led about 1916 measurements to the sensitivity of the eye to detect angular velocities from. (JB Henderson had in 1907 received a secret patent for a similar device. Another similar system had been developed in 1910 and Keith Elphinstone and Harry Egerton Wimperis. ) For one year he was Adjunct Naval attaché at the Russian Embassy in Paris.

In June 1918, he emigrated to the USA where he was assistant to Charles P. Steinmetz in the first four years with General Electric.

His publications from 1922 and 1930, according to he dealt with automatic control of ships. First attempts to servo - controlled rudders were made in 1864. One of the problems was to measure the position of the compass needle without disturbing their accuracy. His early work influenced Harold Locke Hazen (1901-1980), who reported in 1934 on his servo - mechanism. ( Of these learned Vannevar Bush and Norbert Wiener. ) From 1922 to 1923, he investigated on behalf of the Bureau of Construction and Repair of U.S. Navy on the USS New Mexico his ship control with PID control and provided a mathematical analysis. The increased range of the ship's guns had made ​​an accurate control is required. Although the attempts was successful, he had to cut back, because they disliked the team 's control. In 1930, he sold his patent to the Bendix Corporation, which was entered in the previous year in the aeronautics. The system of Elmer Ambrose Sperry, he analyzed and reported on it in 1937 in The Engineer.

1924 to 1934 he was Professor of Electronics and Applied Physics at the University of Pennsylvania. Then he went to the United States Naval Research Laboratory and worked at the David Taylor Model Basin in the stabilization of ships against casters.

During the war he was a consultant of its director and began to be interested in nonlinear problems. From 1946 he worked at the Faculty of Mechanical Engineering, Stanford University. After his retirement in 1950 he lived in South France at the feet of the Pyrenees.
