Those features, along with subsequently improved reliability and lower maintenance costs will improve the aircraft performance and reliability. The

30 is designed to have fewer stages than the AL-41F1 and be up to 18% more effective. Full scale development began in 2011 and the engine's compressor began bench testing in
December 2014. The first test engines were completed in 2016. The new powerplant is designed to be a drop-in replacement for

Although Sukhoi specified the AL-41F1 in the contract, the bureau anticipates that its T-50 design, eventually designated the Su-57, would be the basis for a family of stealth combat aircraft, with future variants employing more powerful engines. Following a competition between NPO Saturn and MMPP

The AL-51F-1 is a two-shaft low-bypass afterburning turbofan engine. The architecture is a three-stage fan driven by a single-stage low pressure turbine and five-stage high pressure compressor driven by single-stage high pressure turbine. Unlike its AL-41F1 predecessor, the engine has glass-fiber

229:
First flight of the engine on an Su-57 prototype occurred on 5 December 2017 with the second prototype (T-50-2, bort no. 052). However, the engineβs development has seen a sluggish flight test pace; originally planned to enter service in the early 2020s, the
