Pratt & Whitney today confirmed that it will offer a Pure Power Geared Turbo Fan engine with 35,000 lbs of thrust, an increase of two thousand pounds from the previously announced model that powers the Airbus A321neo.
Officials declined to confirm our previously reported thrust bump for the Bombardier CSeries GTF, continuing to stick with its prepared statement.
Thrust bumps are largely considered for hot-and-high operations, where the extra boost is needed to get off the runway with maximum payload. In most operations, the extra thrust isn’t needed. The trade for the extra thrust is higher maintenance costs.
Airlines, according to one engineer, tell engine OEMs that they don’t want the extra thrust as the engine is being designed because of the associated extra costs, but then invariably later say they do.
Market Intelligence tells us CFM is going to provide a 35,000 lb model of the LEAP that powers the A321neo and the Boeing 737-9 MAX.
