Airbus H225 flies on 100% SAF in both Safran Makila 2 engines

An Airbus H225 has performed the first-ever helicopter flight with 100 percent sustainable aviation fuel (SAF) powering both Safran’s Makila 2 engines.

This flight, which follows the flight of an H225 with one SAF-powered Makila 2 engine in November, is part of a campaign aimed at understanding the impact of SAF use on the helicopter’s systems. Tests are expected to continue on other types of helicopters with different fuel and engine architectures with a view to certify the use of 100 percent SAF by 2030.

“This flight with SAF powering the twin engines of the H225 is an important milestone for the helicopter industry,” said Stefan Thome, executive vice president of engineering and chief technical officer for Airbus Helicopters. “It marks a new stage in our journey to certify the use of 100 percent SAF in our helicopters, a fact that would mean a reduction of up to 90 percent in CO2 emissions alone.”

The use of SAF is one of Airbus Helicopters’ levers to achieve its ambition of reducing CO2 emissions from its helicopters by 50 percent by 2030. One of the main benefits of using this new fuel is that it allows the aircraft to minimize its carbon footprint while maintaining the same flight performance.

According to the Waypoint 2050 report, the use of SAF in aviation could account for 50 to 75 percent of the CO2 reduction needed to reach net-carbon emissions by 2050 in the air-transport industry. While SAF production currently accounts for only 0.1 percent of total aviation-fuel production, this figure is expected to increase dramatically in the coming years to meet both growing demand from operators and upcoming SAF-usage mandates.

In June 2021, Airbus Helicopters launched the SAF User Group with the intention of bringing all stakeholders together to work on ways to accelerate the use of blended SAF kerosene and to pave the way toward 100 percent SAF flights for future fleets. All Airbus commercial aircraft and helicopters are certified to fly with up to a 50 percent blend of SAF. Airbus’ goal is to achieve certification of 100 percent SAF by 2030 for its commercial aircraft and helicopters.
