(20 Jun 2021)
Airbus, Safran, Dassault Aviation, ONERA and the
of Transport are to jointly launch an in-flight study to analyse
the compatibility of unblended sustainable aviation fuel (SAF)
with single-aisle aircraft and commercial aircraft engine and fuel
systems, as well as with helicopter engines.
Scheduled to commence at the end of 2021, the
project, known as VOLCAN (VOL avec Carburants Alternatifs
Nouveaux), is the first time that in-flight emissions will be
measured using 100% SAF in a single-aisle aircraft.
The study will support efforts currently underway
at Airbus and Safran to ensure the aviation sector is ready for
the large-scale deployment and use of SAF as part of the wider
initiative to decarbonise the industry.
It will also contribute to the ultimate goal of
achieving 100% SAF certification in single-aisle commercial
aircraft and the new generation of business jets.
For the VOLCAN project, Airbus is responsible for
characterising and analysing the impact of 100% SAF on-ground and
in-flight emissions using an A320neo test aircraft powered by a
CFM LEAP-1A engine.
Safran will focus on compatibility studies related
to the fuel system and engine adaptation for commercial and
helicopter aircraft and their optimisation for various types of
100% SAF fuels.
ONERA will support Airbus and Safran in analysing
the compatibility of the fuel with aircraft systems and will be in
charge of preparing, analysing and interpreting test results for
the impact of 100% SAF on emissions and contrail formation.
In addition, Dassault Aviation will contribute to
the material and equipment compatibility studies and verify 100%
SAF biocontamination susceptibility.
The various SAFs used for the VOLCAN project will
be provided by TotalEnergies.
The project is part of the “Plan de Relance
Aéronautique” (the French government‘s aviation recovery plan)
managed by Jean Baptiste Djebbari, French Transport Minister.
