Kirill Shchelkin - Kirakos Metaksyan
Kirill Ivanovich Shchelkin (Russian: Кирилл Иванович Щёлкин) (17 May 1911 – 8 November 1968) was a Soviet physicist of Georgian origin in the former Soviet program of nuclear weapons who made theoretical and experimental contribution in combustion and gas dynamics.
He was notable for his work on the detonation process of the first Soviet nuclear weapon, the RDS-1, and the first thermonuclear device, and for his role as the first scientific director of the Soviet nuclear weapons development center in the Urals at Chelyabinsk-70.
Life and career
He was born in Tbilisi, Russian Empire, and baptised at home by a Russian Orthodox priest. Arminian by nationality.[1] He lived in the Caucasus as a young child. When he was aged seven, his family moved to Krasny, where his father – a land surveyor and his mother, a teacher, both of ethnic Russian extraction – came from. In 1924, his family moved to Karasubazar (now Belogorsk) in the Crimea because his father was suffering from tuberculosis. When his father succumbed to the disease in 1926, the 15-year-old pupil Shchelkin also had to work to support his family. In 1928, he enrolled at the Crimean Pedagogical Institute in the faculty of Physics and Technology, graduating in 1932.[2][3]
After graduation, he was invited to join the Institute of Chemical Physics of the USSR Academy of Sciences in Leningrad as a laboratory assistant. Here he first met Igor Kurchatov, who was to become an important supporter. He researched combustion processes, specifically the suppression of methane explosions in coal mines and suppressing the detonation of fuel-air mixtures in the cylinders of internal combustion engines. In May 1934, scientist published an article in the Journal of Experimental and Theoretical Physics in which he described calculating the frequency of rotation in the newly studied phenomenon known as spin detonation, where the flame front in combustible gaseous mixtures advances (for example) in a spiral manner along a cylinder, which drew the attention of combustion specialists. He also wrote about experiments concerning the effect of irregularities in the walls of mine workings which caused turbulence that could accelerate flame propagation should combustion occur if the chambers were filled with combustible gases. He gained his Ph.D. in December 1938 with a thesis presented to the academy: “On the theory of the onset of detonation in gas mixtures”. Yakov Zel'dovich, an expert in the field, was one of a number of scientists who argued with Shchelkin from the point of view of chemical kinetics made more complex by thermal effects – as opposed to Shchelkin's gas dynamics – but he conceded that Shchelkin's bravery produced exceptional experimental results.[4][5][2][3]
Shchelkin's plans for further research and a further dissertation were interrupted by the Nazi's attack on the Soviet Union. He volunteered and was in the platoon of artillery intelligence of the 64th rifles division, engaged in the fighting to protect Moscow. In 1942, he was ordered to return to the Institute of Chemical Physics (which was evacuated to Kazan) by the Deputy People's Commissar for Defense, Yevgeny Schadenko. He was engaged in research into combustion in jet engines. In 1943, the Institute returned to Moscow, and the following year he was appointed head of the laboratory. In 1946, he wrote a final thesis, "Fast burning and spin detonation" (also published as a monograph in 1949). He was invited to be deputy director of the Institute for Physical Problems at the academy, but he turned down the offer to continue scientific research. Shortly after this, however, he was part of a special committee which discussed the formation of a second nuclear weapons research centre, which became known as Laboratory B, on a peninsula of Lake Sungul', where he worked as part of KB-11 (a secret nuclear weapons development facility based in Sarov, now the All-Russian Scientific Research Institute of Experimental Physics), and where German scientific knowledge was exploited as part of the "Russian Alsos". In 1949, at the test-site in Semipalatinsk, Kazakhstan, Shchelkin supervised the placement of the first Soviet nuclear device on the tower, put the detonating cap on the sphere of plutonium himself (and supervised the later ones). For this success, he received the Hero of Socialist Labour award; several others followed in ensuing years, including for work on the first Soviet thermonuclear weapon.
