TsAGI centenary in history: the Yakovlev Yak-130
17 May 2019
It was in late April in 1996 when the Yakovlev Yak-130 D (a demonstrator aircraft) took its maiden flight. The aircraft was developed by the Yakovlev Design Bureau. The training and combat Yak-130 was created on its basis and became the first production aircraft built in Russia after the collapse of the Soviet Union.
The aircraft thrust/weight ratio and its aerodynamics allow performing tasks in all modes, which are peculiar to the newest aircraft of the fourth and fifth generations. It has a great maneuverability and perfect takeoff and landing characteristics. The Yak-130 has excellent low-speed operational characteristics and a high climb rate.
The Yakovlev Design Bureau developed the aircraft in close cooperation with the Zhukovsky Central AeroHydrodynamic Institute (TsAGI). The Institutes’ specialists contributed much to develop the air intakes, which would provide the effective operation of the aircraft propulsion at wide range of angles of attack. TsAGI’s structural engineers spent a large amount of research to experimentally verify the Yak-130 airframe’s structural life and to identify the fatigue critical areas which limited the aircraft’s life. The tests were conducted at a special test bench which provided the simulation of aerodynamic and inertial forces on all the units of the airframe (high-lift wing, fuselage, vertical and horizontal stabilizer, engine attachment fittings and landing gear) for non-flight and flight modes, which statistically represented the loading in service.
The obtained data allowed confirming experimentally the airframe’s and landing gear’s fatigue as well as improved the background for appointing the operational practices. All the listed above provided the reliability and safe operation of the entire fleet of Yak-130. TsAGI has been holding the aircraft endurance tests till present time.
In 2016, the Yak-130 set Russian and world records in climb rate at different altitudes with the payload and without it in the class of mass-produced turbojet aircraft with ground-based takeoff and weight from 6,000 to 9,000 kg.
Now the aircraft is mass-produced at the Irkutsk Aviation Plant- the branch of Irkut Corporation JSC and have been successfully in service at the Russian Aerospace Forces and abroad.
