Smooth Going for GTF Allows Pratt to Extend Thrust Rating
The PW1135G turbofan provides 35,000 pounds of thrust for the Airbus A321.
Pratt & Whitney expects to gain certification of the first version of the PW1100G for the Airbus A320neo during the second half of the year.

Pratt & Whitney’s launch on Tuesday of a 35,000-pound-thrust version of its Geared Turbofan extends the family’s power range by another 2,000 pounds, giving Airbus A321neo customers enough range and payload capability to effectively operate from such hot and high locations as Mexico City and Bogota. Dubbed the PW1135G-JM, the engine gets its extra thrust from leftover development margin extracted from the design of the family as a whole, thereby requiring no hardware or design changes, explained Pratt & Whitney vice president of engineering Tom Prete.
