On the occasion of the Paris Air Show, Elixir Aircraft unveiled its prototype for a low-carbon propulsion aircraft at the Paris Air Lab. Developed as part of a CORAC program in collaboration with Air Liquide, Safran, Daher and Turbotech, the aim of this program is to accelerate the market launch of innovative, more environmentally-friendly aircraftpowered firstly by biofuel and then by hydrogen. Discover this aircraft on the static display of the “Paris Air Lab” stand B3.
Elixir Aircraft has set itself the mission of decarbonizing general aviation, while retaining the advantages it brings. It’s a mission that the company has decided to tackle pragmatically, with the question: what “clean” energies will enable light aircraft to carry out their missions in the future? There are several answers to this question, and choices have to be made. Will the solution be electric, with batteries? Hydrogen with a fuel cell? Hybrid electric? Thermal hydrogen (liquid, gas?)? Thermal biofuel (which?)?
Faced with these questions, Elixir Aircraft has chosen its positio. First of all, biofuels such as aviation kerosene (SAF) and then liquid hydrogen.
Ultimately, the future is dictated by what works today. Commercial aviation has been moving towards biofuels for 15 years, and rightly so. This high-energy-density fuel does not change engines, pilot training, maintenance or distribution methods… It just needs to be mass-produced. Given the sheer volume of fuel needed to power commercial aviation, it’s reasonable to assume that one or more energy suppliers will eventually be able to produce it in quantity and at a reasonable price. As SAF is already distributed to airports worldwide, this choice of fuel seems to Elixir Aircraft to be the best compromise for the future of its propulsion.
Elixir Aircraft is therefore in the process of integrating Turbotech’s TP90 turbine, running on biofuel (SAF), into its 4th-generation aircraft. This aircraft, currently under development, is being unveiled for the first time at the Paris Air Show, on stand B3 “Paris Air Lab”.
Given the long development and certification time involved in aeronautics, the SAF is the sensible choice, but it’s a wise second choice. Liquid hydrogen as a complement to SAF propulsion is a choice that, while far from mature, makes sense. Many manufacturers are interested, including producers/distributors (Air Liquide), and the technological building blocks are available (storage, combustion, distribution). All that remains is to clear the way to integrate the whole system into a device, make it reliable and certify it. This is what the members of the CORAC hydrogen consortium are working on.
