MTU Aero Engines AG (MTU), Pratt & Whitney, Collins Aerospace (Collins), GKN Aerospace, Airbus and others aim to demonstrate the potential of these technologies to improve fuel efficiency and reduce aircraft emissions, with a goal of achieving up to 25% improvement in fuel efficiency and reduced CO2 emissions compared to today’s state-of-the-art propulsion systems for short- and medium-range aircraft. The consortium is coordinated by MTU.
The Sustainable Water-Injecting Turbofan Comprising Hybrid-Electrics (SWITCH) project is focused on developing a novel propulsion concept built from two revolutionary and synergetic technologies: Water Enhanced Turbofan (WET) and hybrid-electric propulsion. By combining these technologies with Pratt & Whitney’s GTF engine architecture, the SWITCH concept aims to significantly enhance efficiency and substantially reduce emissions across the full operating envelope of an aircraft. Technologies developed as part of SWITCH will be fully compatible with cleaner alternative fuels, such as Sustainable Aviation Fuel (SAF) and will be evaluated for future use with hydrogen.
“This highly impactful SWITCH consortium provides a unique opportunity to demonstrate the benefits of both WET and hybrid-electric propulsion technologies, not only independently, but as parts of a system,” said Dr Stefan Weber, senior vice president, Engineering and Technology, at MTU. “WET offers considerable potential to boost efficiency and reduce all emissions significantly for future aircraft propulsion systems, whether they are powered by conventional kerosene, SAF, or even hydrogen. Since the concept is gas turbine based, the WET concept fully leverages MTU’s expertise.”

Sustainability and connectivity: top of the agenda for private jet industry
The executive aviation industry is currently facing a paradox. On the one hand, demand for private flying remains strong, propelled by the rise in the number of high-net-worth individuals around the globe. While on the other hand, the industry is increasingly being questioned by the public, the media, and politicians over its environmental credentials.
NASA, ESA join forces to land European Rover on Mars
The space agencies signed a new agreement that will see NASA supply heating units for the Rosalind Franklin rover, which could launch as soon as 2028.
Long-awaited Starliner launch breaks a six-decade drought
An Atlas rocket has launched with astronauts aboard for the first time since Gordon Cooper's final Mercury flight in his Faith 7 capsule on 15 May 1963, powered by an Atlas LV-3B 130-D. The Atlas V rocket that launched on 5 June, manufactured by United Launch Alliance and powered at liftoff by a Russian-built RD-180 first-stage engine, carried Boeing's Starliner crew ferry ship to orbit following multiple launch delays over the past several days.
Non-CO2 emissions measured in commercial aircraft 100% SAF test
Results from the world's first in-flight study of the impact of using 100% sustainable aviation fuel (SAF) on both engines of a commercial aircraft show a reduction in soot particles and formation of contrail ice crystals compared to using conventional Jet A-1 fuel.
Avfuel, Neste sign SAF supply increase extension
Avfuel and renewable fuel producer Neste have finalised an extension to their agreement regarding the supply of sustainable aviation fuel (SAF) and set a framework for the deal through 2027.
First flight for Electra hybrid 'blown lift' aircraft
Electra's blown-lift design uses eight electric motors to increase wing lift, allowing the eSTOL aircraft to take-off and land in just one-tenth of the space needed by conventional aircraft.
Saudi Arabia's groundbreaking air taxi trial set to transform Hajj travel for pilgrims
In a historic move, Saudi Arabia has successfully conducted its first air taxi trial in Mecca, setting the stage for deployment in the coming years and transforming Hajj transportation for pilgrims.
Lilium, French Government in 'advanced' talks for eVTOL jet manufacturing hub
The German manufacturer says it is in ‘advanced discussions’ with the French government to add a high-volume aircraft production facility in France, citing it as an attractive market for its flagship Lilium Jet. The company plans for the aircraft to enter service in 2026.
Joby partners with Mukamalah Aviation
Last month Joby Aviation announced it has signed a Memorandum of Understanding (MoU) with Mukamalah, a wholly owned subsidiary of Saudi Aramco, the operator of the world's largest fleet of corporate aircraft, to introduce Joby's aircraft to the Kingdom of Saudi Arabia.
Joby acquires autonomous flight developer Xwing
Joby Aviation is one of many electric vertical take-off and landinng (eVTOL) air tax manufacturers that predicts autonomy will be the driver of ubiquitity for advanced air mobility (AAM) services and the company is placing its money where its mouth is.
