Russia's New 4 Mach Capable 5th-Gen Soyuz AMNTK R579-300 Turbojet Engine For VTOL Aircraft

The R579-300 is a fifth-generation turbojet engine specifically designed for vertical takeoff and landing (VTOL) aircraft, showcasing advanced propulsion capabilities. With a maximum afterburner thrust between 21,000 and 23,000 kgf, the engine stands out for its high performance and adaptability. Its key features include an adjustable bypass and compression ratio, which enhance thrust and fuel efficiency across various flight conditions.

Notably, the engine can generate over 40 megawatts of power and produce a robust cold air flow, making it particularly attractive for military aviation applications. It is being considered for integration into light multifunctional fighters and strategic unmanned aerial vehicles (UAVs) capable of speeds exceeding Mach 3-4.

Compared to the F-35 B's Pratt & Whitney F135 engine, the R579-300 differs in several important aspects. While both engines support VTOL operations, the R579-300 is a turbojet with superior high-speed performance and thrust-to-weight ratio. The F135, a turbofan, offers more efficient fuel consumption and lower noise levels, with its unique pivoting nozzle technology enabling versatile flight profiles.

The engine is currently in development, with experts viewing it as a promising alternative for future Russian military aviation platforms. However, its exact timeline remains uncertain, and comprehensive testing will be crucial before operational deployment.
