With the Geared Turbofan™ (GTF) engine, Pratt & Whitney and MTU are building the commercial propulsion system of the future. Its technological masterpiece is a reduction gearbox between the fan and low-pressure shaft on which the low-pressure compressor and low-pressure turbine that drives the fan are seated. The gearbox allows the fan with its large diameter to rotate more slowly, while the low-pressure compressor and turbine can rotate much faster. In this way, each component can run at its optimum speed. This results in a 16 percent reduction in both fuel consumption and carbon dioxide emissions and in a 75 percent smaller noise footprint—great news for airlines, the environment and for humankind.
MTU contributes a key component to the engine: the high-speed low-pressure turbine. Germany’s leading engine manufacturer is the only company in the world capable of offering this technology. And that’s not all—MTU also manufactures brush seals and the first stages of the engine’s high-pressure compressor.
