Andronik Gewondowitsch Iossifjan ( Armenian Անդրանիկ Ղեւոնդի Հովսեփյան , Russian Андроник Гевондович Иосифьян ; born July 8 ^{. Jul} / 21st July  1905 ^greg. In the village Zmakaoch in Martakert in Karabakh ; † 13. April 1993 in Moscow ) was an Armenian - Russian electrical engineer and Rocket engineer .

Life

Iossifjan joined the Red Army at the age of seventeen . In 1925 he graduated from RabFak and began studying electromechanics at the Baku Polytechnic Institute . In 1930 he began work in the electrical machine laboratory of the Moscow All-Russian Electrical Engineering Institute . In 1936 he was the first in the Soviet Union to propose the use of the thyratron to control DC machines and developed the theory for the amplifiers . In 1939 he was the world's first to design a linear motor , which he successfully presented in the form of a model railroad at the New York World's Fair . On behalf of the People's Commissariat for Defense and the Navy , together with the physicists K. S. Wulfson and AA Smirnow, he developed a system for locating and tracking ships using infrared radiation . In 1941 he was appointed professor.

In 1941, at the beginning of the German-Soviet War , Iossifjan was sent to a small factory to build the remote-controlled small tanks he had developed for blowing up enemy tanks . This was the nucleus of the later development plant No. 627 in Istra with Iossifjan as director. In 1945 he became a corresponding member of the Armenian Academy of Sciences (AN-ArmSSR) .

Following the decision of the Council of Ministers of the USSR on rocket armament on May 13, 1946, the plant was expanded to include additional buildings. The production of electrical inverters had to be organized to provide alternating current with a voltage of 40 V and a frequency of 500 Hz for the supply of the rocket gyroscopes . To do this, the need for lightweight electric motors , potentiometers and relays had to be satisfied. Iossifjan was now the main design engineer of the electrical equipment of the missiles. One of his most important developments was contactless energy transfer . 1953 was Iossifjans initiative with the development of the minicomputer M-3 of IS Bruk and NJ Matjuchin begun. 1955-1965 he was editor-in-chief of the magazine Elektrotechnika . In 1956 he founded the Institute for Mathematical Machines in Yerevan together with SN Mergeljan .

The electric rocket equipment developed by Iossifjan was used in the R-7 rocket from SP Koroljow and proved itself in the Sputnik 1 flight in 1957 and later in the Vostok spacecraft . Iossifjan's work No. 627 was incorporated into the All Union Research Institute for Electromechanics (WNIIEM) in 1959 and became its subsidiary in Istra. In 1959 Iossifjan became a full member of the AN-ArmSSR and in 1960 a doctorate in technical sciences .

In 1960, Iossifjan was involved in testing the R-16 missile that led to the Nedelin disaster in 1960 . In 1966 the Kosmos-122 carried the first experimental meteorology system into orbit , which was put into operation in 1967 in Kosmos-144 and Kosmos-156 and was further developed into the Meteor satellites under Iossifjan's direction .

Iosifjan was the chairman of the Science Council for Aerospace Electrical Engineering and Electronics of the Academy of Sciences of the USSR (AN-SSSR) .

Iossifjan found his grave in the Troyekurovo cemetery in Moscow .
