The Russian aircraft industry has, over the years, produced a staggering number of aircraft, large and small, for civil and military purposes. These aircraft have been powered by an equally extraordinary number of engines, built in Russian factories to both native and foreign designs. This detailed study of the piston aero engines produced by Russian factories form the birth of flight to the present is a tour de force of historical research, which has used many resources and archives not previously known in the west. The book includes every piston engine built from an original Russian design or copied from a foreign design; from engines used in the first Russian flying machines to microlight engines still I production. Each is written with its history, specifications and details of use.
