MTU Aero Engines is exploring advancements such as gas turbine engines with a geared turbofan and concepts such as a water-enhanced turbofan and flying fuel cell as it strives for a goal of emissions-free flight. The German engine maker is detailing its efforts through an update on its Clean Air Engine technology agenda during the 2022 Farnborough International Airshow.

The agenda covers potential solutions and concepts for sustainable commercial engines and provides timelines for them. MTU sees three primary stages toward emissions-free flight with alternatives such as hydrogen and sustainable fuels playing a key role alongside technological developments. The first stage involves the geared turbofan, which it said could significantly reduce climate impact in conjunction with sustainable aviation fuel. The second, targeting the 2035 timeframe, would encompass the water-enhanced turbofan and the flying fuel cell, as well as a possible hydrogen-powered geared turbofan.

Longer-term, targeting 2050, MTU believes the third stage will involve further efficiency gains through new propulsion with the use of fuel cells on short- and medium-haul routes.

On the military side, MTU (Hall 1, Stand 1116) also is using an interactive exhibit to present concepts behind its innovations for the Next European Fighter Engine that would power the sixth-generation European fighter aircraft. It further has an interactive exhibit for repair technologies.

In addition, MTU is hoping to use Farnborough Airshow as an avenue for recruitment, and human resources specialists are at its stand to advise visitors on career and advancement opportunities.
