Russian engine maker unveils cutting-edge aircraft engine

"The state-of-the-art 177S engine for tactical aircraft boasts improved characteristics and is of the fifth generation class," the press service said

ZHUHAI, November 12. /TASS/. The United Engine Corporation (UEC) has unveiled the fifth generation of its 177S engine at the Airshow China 2024, the company’s press service says.

"The global premiere of the high efficiency fifth generation 177S engine, which increases the flight range of tactical aircraft, will take place in China. The state-of-the-art 177S engine for tactical aircraft boasts improved characteristics and is of the fifth generation class," the press service said. The engine's improved fuel consumption rate in all operating conditions reduces costs, UEC said. "Furthermore, the engine supports the increased power consumption for electronic systems of modern airplanes. The powerplant also increases their flight range," the corporation noted.

UEC also showcases full-size mockups of new AL-31FN Series Five and SM-100 engines to foreign partners.

"The engines presented in China have several characteristics marking them as fifth generation. Furthermore, breakthrough engineering solutions enable their optimization to meet customer requirements and expand the set of options. An indisputable advantage of Russian engines is the opportunity to upgrade prior generation engines to the cutting-edge version during the overhaul. Their lifetime or thrust can be increased in such case," CEO of UEC Alexander Grachev said.
