What is the bypass ratio of the GE F404?
For the F/A-18, GE based the F404 on the YJ101 engine they had developed for the Northrop YF-17, enlarging the bypass ratio from 0. The F404 Engine GE Aerospace’s F404-GE-103 features the latest technologies to improve engine durability, simplify maintenance, and enhance single-engine safety to support advanced jet training for the next generation of military pilots.
What is a good bypass ratio?
Modern engines in slower aircraft, such as airliners, have bypass ratios up to 12:1; in higher-speed aircraft, such as fighters, bypass ratios are much lower, around 1. Mach 2 and somewhat above have bypass ratios below 0. As bypass ratio (BPR) increases the overall efficiency of the engine increase which is a primary factor that yields lower TSFC for the turbofan engine. Additionally this report shows that a high bypass ratio engine can produce a greater amount of thrust while consuming the same amount of fuel as a lower BPR engine.The ratio of (m dot)f to (m dot)c is called the bypass ratio – bpr. The total mass flow rate through the inlet is the sum of the core and fan flows. A turbofan gets some of its thrust from the core and some of its thrust from the fan.
What is the spec of the FJ44-4A?
The FJ44-4A is built to deliver exceptional performance, fuel efficiency, and reliability, generating 3,621 pounds of thrust each, and providing a combined total of more than 7,200 pounds for an aircraft with a maximum takeoff weight of 18,500 pounds—yielding an impressive 38. Delivering 3,400lb (15. N) of thrust, the FJ44-4M has a speci c fuel consumption of 0. TBO) of 3,500 flight hours.The FJ44-4A is built to deliver exceptional performance, fuel efficiency, and reliability, generating 3,621 pounds of thrust each, and providing a combined total of more than 7,200 pounds for an aircraft with a maximum takeoff weight of 18,500 pounds—yielding an impressive 38.Size & Weight: FJ33 is smaller/lighter for VLJ class; FJ44 targets light-jet and some midsize applications. Thrust: FJ33 ~1,000–1,900 lbf; FJ44 typically ~1,900–3,600+ lbf depending on variant. Use Cases: FJ33 for single-engine VLJs or ultra-light twins; FJ44 for aircraft like Citation CJ/M2 and other light jets.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.
