A few months ago, Pratt & Whitney announced a new version of its Geared Turbofan, the Advantage. More powerful but also more efficient and with a one-percent better fuel consumption compared to the base GTF, the Advantage will enter service on the Airbus A320neo-family in 2024.
But there is another step to come in the efficiency of the GTF. B
ehind the scenes, P&W’s German partner MTU Aero Engines has been working on a revolutionary program called WET, short for Water Enhanced Turbofan. MTU’s WET concept further improves GTF efficiency.

MTU has been closely involved in the updates that are now part of the Advantage program, notably the high-pressure compressor (HPC) and the low-pressure turbine (LPT) to improve the airflow through the engine. Striving to offer solutions capable of reaching the goals of the 2015 Paris Climate treaty to limit global warming, MTU has been pushing ahead for new solutions. One of these is WET, a revolutionary concept to reduce climate impact while at the same time improving efficiency.
