Pratt & Whitney PW4000-112
Pratt & Whitney PW4000-112 is the 112-inch-fan turbofan class for Boeing 777-200/-200ER/-300. Pratt & Whitney's fact sheet gives a 74,000–98,000 lbf takeoff-thrust range (normalized upper bound here to 435.9 kN), 5.8–6.4 bypass ratio, 34.2–42.8 overall pressure ratio, 112 in fan tip diameter, and 191.7 in flange-to-flange length. The class contains PW4074/74D/77/77D, PW4084D/90/90-3, and PW4090/90-3; exact model and aircraft installations remain separate records.
