Bartini initially worked at an airport near Khodynka Field in Moscow before occupying several engineering and command positions for the research wing of the Soviet Air Force. In 1928, Bartini began working for the Central Design Bureau building seaplanes near Sevastopol and the following year became the head of the department of amphibious experimental aircraft design, but was fired in 1930 for writing a letter to the Central Committee of the CPSU criticizing the existence of the organization. Bartini was quickly hired by the research wing of the Red Army where he began working on the Stal-series of airplanes. At the International Exhibition in Paris in August 1936, the Bartini Stal-7 broke the international speed record. He also published papers concerning aviation construction materials and technology, aerodynamics, dynamics of flight, and even theoretical physics. In 1938, Bartini was arrested by the NKVD on charges of being an "enemy of the people" and a spy for Fascist Italy. He was extrajudicially convicted by a troika, receiving a 10-year imprisonment sentence. During his imprisonment Bartini continued his work on new aircraft designs, first at the sharashka TsKB-29, an NKVD experiment aircraft design bureau in Moscow where he worked with Andrei Tupolev designing the Tupolev Tu-2, which became one of the most important Soviet aircraft of World War II. Bartini's Stal-7 plane also became the base for the Yermolayev Yer-2 bomber, also used by the Soviet Air Force during the war. When German troops were close to Moscow during the German invasion of the Soviet Union, TsKB-29 was moved from the city to Omsk where Bartini led his own design bureau, OKB-86. His bureau was disbanded in 1943, and he began working on various transport plane projects. Bartini was released in 1946, later working at the Dimitrov Aircraft Factory in Taganrog until 1952, when he became the chief engineer of advanced aircraft designs at the Scientific Research Institute in Novosibirsk. In 1956, during the De-Stalinization under Nikita Khrushchev, Bartini was officially rehabilitated by the Soviet state. The following year he was transferred to the OKBS MAP design bureau in Lyubertsy with Pavel Vladimirovich Tsybin, and received backing from Marshal of the Soviet Union Georgy Zhukov, at the time the Minister of Defense of the USSR. Zhukov was forced out the position shortly afterwards, and most of the projects he backed were cancelled. In 1961, Bartini had proposed a nuclear-powered
