The PD-8 turbofan successfully completed 150-hour certification tests at maximum operating conditions. The program was carried out by UEC-Saturn as part of the powerplant certification for the Sukhoi Superjet 100 (SSJ100).
Tests were conducted at UEC Aviadvigatel’s test stand in Perm over approximately six weeks. The engine accumulated 150 hours of operation — equivalent to more than six continuous days. “During certification, the engine was subjected to extreme loads to verify its operational safety under real-world conditions,” the corporation stated.
The test program required simultaneous achievement of maximum thrust and critical operating parameters, including rotor speeds, gas temperatures, and fuel and oil pressures. “All parameters were pushed concurrently with maximum thrust,” explained Artem Badernikov, Deputy Chief Designer for Modules and Systems at UEC-Saturn.
The 150-hour campaign simulated extended engine operation and confirmed performance and safety compliance under loads beyond normal service conditions. The program was executed by a joint team from UEC-Saturn and UEC Aviadvigatel without deviations. Collected data will be included in the PD-8 certification report required for type certification.
Earlier, the engine passed bird-strike and water ingestion tests, fan blade-out scenarios, acoustic tests, crosswind operation, and thrust-reverser trials. All key tests were conducted at thrust levels exceeding 17,600 lb (8,000 kgf).
The PD-8, rated at 17,600 lb of thrust, is developed by UEC-Saturn for the Superjet 100 and Beriev Be-200. A full-scale engine is displayed at the NAIS 2026 Civil Aviation Infrastructure Exhibition in Moscow, February 4–5. In late January, an SSJ100 powered by PD-8 engines (serial 97024) was showcased at the Hyderabad Airshow in India.
