First helicopter engine runs using 100% sustainable fuel

Bordes, September 8, 2021

Safran Helicopter Engines today completed a first at its Bordes site (Pyrénées-Atlantiques, France):  the end of a helicopter engine test campaign using 100 percent sustainable aviation fuel (SAF). During this campaign, a Makila 2 ran on a biofuel produced by TotalEnergies from residues and  waste from the circular economy, specifically used cooking oil. 

This test campaign has evaluated the operational impact of using only SAF on a helicopter engine.  To do this, the engine manufacturer utilized a Safran Tech special facility known as "Bearcat" (Banc  d’Essai Avancé pour la Recherche en Combustion et Aérothermique des Turbomachines), an  advanced test bench for turbomachinery combustion and aerothermal.

Franck Saudo, CEO of Safran Helicopter Engines says, "after the first flight of a rescue helicopter  using 40% SAF in June, and the fuel’s gradual introduction for engine tests at our sites since July,  we are now taking a new step toward using fuel made entirely from renewable sources. This test  campaign is a key step in the realization of future test flights with our helicopter partners. The use of sustainable fuels among helicopter operators and at our sites, is a promising lever to significantly  reduce CO2 emissions over the entire life cycle of our products". 

"By offering our customers like Safran sustainable aviation biofuels produced in France, we are  meeting a strong demand from the aviation industry to reduce its carbon footprint. The development  of biofuels is one of the main thrusts of TotalEnergies' multi-energy strategy to meet the challenge  of decarbonizing the transportation sector. This is fully in line with the Company's climate change  ambition of achieving carbon neutrality by 2050," said Virginie Merini, Senior Vice President,  Renewable Fuels at TotalEnergies. 

Safran engines are already certified to operate with up to 50% SAF. With 100% incorporation, the lower carbon footprint of these fuels will reduce CO2 emissions by up to 80%.
