Life

Kotscherigin lost his parents in early childhood and grew up in an orphanage. A scholarship enabled him to attend middle school. In 1912 he began studying at the Technological Institute in Petersburg. He earned the financial means for this as a locksmith, stoker, auxiliary machinist, designer and tutor. In 1914 he worked as a draftsman at the Baltic shipbuilding yard.

During the First World War , Kocherigin was employed in France as a technician to check French weapons and equipment bought by Russia. For a while he was at the front, but also completed theoretical seaplane courses and worked on the construction of seaplanes. After the October Revolution , he completed his training as a sea pilot at the Petrograd Polytechnic Institute. He then worked as a flight instructor and in 1920 tested, among other things, the “Engels III” flying boat. In 1921 Kotscherigin began training as a designer at the Air Force Military Academy . In addition, he worked as an aircraft mechanic and designer in Plant No. 2 “ Awiachim ”.

From around 1926 Kotscherigin began his actual work as an aircraft designer in the "OSS", a department of the ZKB , headed by Nikolai Polikarpow . In 1932 he was appointed head of the reconnaissance aircraft department and developed several types of aircraft, of which the two-seat DI-6 fighter aircraft was the most successful and over 200 copies were built. From 1936 to 1938 Kotscherigin was responsible for the preparation of the series production of the US bombing and reconnaissance aircraft Vultee V-11 , which was built under license in the Soviet Union as BSch-1 and the passenger version as PS-43 31 times. In 1942 Kotscherigin's design office was closed .
