Official factory photograph of the Yakovlev UT-1 (AIR-14) single-seat advanced trainer at the Yakovlev Design Bureau airfield in 1936. Currently preserved at the Vadim Zadorozhny Technical Museum.
Factory Documentation of the Yakovlev UT-1 (AIR-14):
This official pre-war photograph, taken in 1936 at the Yakovlev OKB (Design Bureau) factory airfield, captures a pristine Yakovlev UT-1 (initially designated AIR-14) single-seat advanced flight trainer.
Staged outside the main assembly hangars for technical documentation, the aircraft displays its factory demonstration livery, complete with streamlined aerodynamic wheel spats (pants) over the main landing gear and a two-blade wooden propeller.
Design Purpose: Transitioning to Monoplane Fighters:
Designed under the leadership of young Alexander Sergeyevich Yakovlev, the UT-1 was specifically developed to bridge the tactical training gap between slow, forgiving primary biplane trainers (like the Polikarpov Po-2/U-2 and UT-2) and high-speed monoplane fighters (such as the Polikarpov I-16):
- Lightweight Wooden Construction: Built primarily of wood, fabric, and steel tubing, the UT-1 was extremely lightweight, empty weighing just 420 kg (926 lbs).
- Powerplant: Powered by an air-cooled 5-cylinder Shvetsov M-11M radial engine producing 100 to 110 horsepower, providing a top speed of 249 km/h (155 mph).
- Demanding Flight Characteristics: Due to its small wingspan and high wing loading, the UT-1 was notoriously sensitive to control inputs. It required high piloting precision, making it an exceptional tool for advanced aerobatic instruction and dogfight combat preparation.
Preservation at the Vadim Zadorozhny Technical Museum:
The exact aircraft shown in this historical factory documentation photo survived the turbulent pre-war era and World War II.
Today, this historic UT-1 trainer is fully restored and on public display, suspended inside the main exhibit hall of the Vadim Zadorozhny Technical Museum located along the Ilyinskoye Highway near Moscow, Russia, serving as a rare surviving artifact of early Soviet aviation history.
