The Lyasunov TRM-500 (Dulebian: Лясунов Турбореактивный Мотор 500-ой серии, tr. Lyasunov Turbofan Engine 500 series) is a medium- to high-bypass (depending on variant) geared turbofan engine. The engines develop 57–93 kN (13,000–21,000 lbf) of thrust depending on the variant, and have variable bypass ratio depending on the variant. The engine family features three members, the TRM-500A, TRM-500B and the TRM-500S, a deforced variant with decreased bypass ratio and increased efficiency for smaller aircraft. Currently, the engines are used as a sole option for the Dulebian DRJ regional jet family, more accurately for DRJ-75 and DRJ-105 aircraft, and on Lyasunov's flying boat, Lyasunov L-42. In 2017, Lyasunov signed a contract with NACA, Dulebia's main aircraft consortium. According to it, Lyasunov remained in charge of combusting compartment and the compressor, control system FADEC, transmissions (accessory gearbox, transfer gearbox), crank shaft maintenance and overall engine integration. The engine is remarkable for its reduced ground noise, which is 25% below the relative Erdaran Aircraft Regulation standard of 25 db.
The TRM-500 series provide relative efficiency compared to other small turbofan engines, and Lyasunov claims that on regional routes they're comparable to some turboprop engines in terms of efficiency and, most notably, CO2 emissions.
