The Yakovlev UT-2 (other designations: AIR-10) was a Soviet, all-wooden, low-wing training training aircraft with a fixed landing gear. The drive was provided by a single M-11 or M-11D / K engine with the power of 100 and 125 HP respectively . The flight of the prototype took place in 1935, and in the period 1937-1947 serial production continued, which resulted in the creation of about 7,200 aircraft of this type.
Due to the rapid expansion of the Soviet air force in the 1930s, it was necessary to create a new, basic training aircraft. After a series of trials and tests, the UT-2 turned out to be it. The machine was characterized by simplicity of construction, ease of servicing, provided a decent level of flight safety, and had good maneuverability and maneuverability for an aircraft of this class. In total, several versions of this machine were created in the course of a long and intensive series production. The first, mass-produced, was the UT-2 (until 1940 it was called AIR-10). From 1941-1942, an improved version of the UT-2M was introduced into production, which had better aerodynamic properties and ensured greater safety in flight. A version of the UT-2MW with a covered pilot's cabin was also created. This version was later upgraded to the UT-2L standard, which in turn became the basis for the development of the Yak-18. In the period immediately preceding the outbreak of World War II and in its course, the UT-2 machines were the basic training and training aircraft of the Soviet Air Force. They served until the 1950s. Poland and Hungary also used them.
