What model engine is the FJ44?
The FJ44 was developed in 1985 as an all new class of light turbofan engine, initially in partnership with Rolls Royce PLC, and was first flown on the Scaled Composites Triumph concept aircraft. The first commercial application was the FJ44-1A on the Cessna 525 Citation Jet. FJ44-4M is the fully aerobatic version of FJ44-4A engine. It is a modern two–spool co–rotating turbofan engine with medium bypass ratio, mixed exhaust, and high cycle pressure ratio.
