Domestic Powerplant Replaces French-Russian SaM146 On Superjet
Russia’s United Engine Corporation (UEC) has completed certification tests for the Aviadvigatel PD-8 turbofan, a domestically built engine designed to replace the French-Russian SaM146 on the import-substituted Yakovlev SJ-100 regional jet. The engine has accumulated close to 6,600 hours of total operation, including 1,449 hours of flight testing. The PD-8 is intended to power both the SJ-100 and the Beriev Be-200 amphibious firefighter. According to Rostec, the engine has demonstrated high reliability and safety, even under critical conditions. The completion of testing is a precondition for certifying the SJ-100 itself, as reported by AeroTime.
