Biography
Born in a noble family of a Russian psychiatrist , Professor O. A. Chechott . He was brought up with his brother G. O. Chechott , who later became a famous Russian mining engineer, and his sister Maria ( married to Poplavskaya; 1870-1936), the future sculptor.
In 1892 he was released at the end of the Fifth St. Petersburg Gymnasium .
In 1897 he graduated from the St. Petersburg Institute of Railway Engineers.
In 1904 - 1905 He proposed a method for straightening the longitudinal profile of a railway, and in 1909 he developed an original method for determining the speed and time of travel, taking into account the inertia of a train. Chechotta's method made it possible to reduce the analytical calculations to the construction of graphical tables that ordinary road workers could use. In this regard, in 1910 he published the book “A New Method for Calculating Distillation Time”.
In 1911, he suggested using compound machines with superheated steam.
He was a supporter of the idea of sharing the machine double expansion with overheating. In honor of his locomotives, carried out on this principle, had the index "h" (Sc, Lt, Och, UH, etc.).
In 1914 he became a professor in the department of steam locomotives at the Institute of Railway Engineers.
After the October Revolution and the Civil War during the post-war devastation emigrated abroad.
From 1922 he lived in Poland .
C 1927 he taught at the Warsaw Polytechnic Institute .
From 1928 he began working at the Ministry of Railways in Warsaw, studying the movement of locomotives. On his initiative, they created a movement research laboratory in the mechanical department of the Ministry of Railways. In particular, an original method was developed for studying additional resistance when a locomotive is moving. Until 1938, the technical characteristics of 26 different types of locomotives were established.
In 1933 he led the construction of a measuring laboratory in Romania to study locomotives.
In 1934 - 1937 he worked in Tehran during the construction of the Iranian railways.
During the German occupation, was engaged in theoretical work at home.
Shortly after the liberation of Warsaw by Soviet troops, on February 6, 1945, he returned to work at the Ministry of Railways of Poland. He developed a new method for testing locomotives, on the basis of which the Polish and European locomotives Tr202, Ty45, Tu2, Ty43, Ty246 were studied, their performance characteristics were prepared.
In 1951, he moved to the just-created Railway Research Institute, where he organized a flue gas and steam traction laboratory. He took part in the study of the newly built locomotives of the TKt48, Ol49 and Ty51 series. He was the author of many publications in Poland and abroad.
He died on November 3, 1955 in Warsaw.
