Pratt & Whitney PW4000-94
Pratt & Whitney PW4000-94-inch is the first PW4000 family model and a high-bypass turbofan variant for Boeing 747/767, MD-11, Airbus A300/A310, and related freighter or military applications. Pratt & Whitney specifies a 52,000–62,000 lbf takeoff-thrust range (upper bound normalized here to 275.8 kN), a 94 in fan tip diameter, 132.7 in flange-to-flange length, 4.8–5.0 bypass ratio, and 27.5–32.3 overall pressure ratio. It entered revenue service in 1987; individual PW4052/56/60/62/62A, PW4152/56A, PW4158, and PW4460/62 models remain separate identities.
