Rostec which operates as Russia's state defence conglomerate announced that the Su-57 Felon fighter with its fifth-generation design achieved its initial flight using the new Izdeliye 177 engine. The company announced this flight as a new testing phase for the Su-57 program while experts view this development as a significant achievement in Russia's pursuit to develop its own fifth-generation engine.
The Su-57 aircraft has operated with AL-41F1 (Izdeliye 117) engines since its inception. The AL-41F1 engine provides both high thrust output and excellent flight control capabilities which experts classify as a 4++ generation design based on its evolution from previous engine generations. Its limited super cruise performance, higher infrared signature and shorter service life compared to Western fifth-generation benchmarks have long been cited as key constraints on the Su-57’s full operational potential.
The new Izdeliye 177 engine is presented by Russian industry as a powerplant designed from the outset to meet fifth-generation requirements. It is expected to deliver higher thrust, improved consumption efficiency, a modern digital engine control architecture and reduced infrared signature. In operational terms, these features are intended to enhance the Su-57’s super cruise capability, combat radius and overall mission performance.
The Su-57 aircraft now operates with the Izdeliye 177 engine which shows progress in fifth-generation propulsion systems after using improved 4++ generation engines for several years.
Rostec which operates as Russia's state defence conglomerate announced that the Su-57 Felon fighter with its fifth-generation design achieved its initial flight using the new Izdeliye 177 engine. The company launched this flight to test the Su-57 program while experts consider this development as a major success in Russia's efforts to create its own fifth-generation engine.
The Su-57 aircraft has used AL-41F1 (Izdeliye 117) engines since its first flight. The AL-41F1 engine delivers high thrust power and exceptional flight management abilities which experts identify as a 4++ generation design because it developed from previous engine designs. Analysts note that the aircraft’s long-term combat credibility and export appeal will depend heavily on whether the Izdeliye 177 can be successfully matured, certified and produced at scale.
