WILL PROPULSION GO ELECTRIC? ■ Developments in in battery energy density in in the short and medium term will limit electric or highly hybridized propulsion to short-distance low-capacity flights: training aircraft aircraft small shuttles regional aircraft aircraft in in in the medium term and new aircraft dedicated to VTOL or STOL urban/suburban air transport Coupled with this the hybridization of propulsion systems on on on future aircraft and helicopters will help meet the ambitious targets for reduced fuel burn Safran is a a a a a a leader in all- electric and hybrid architectures developing a a a a range of products for the electrical power chain — motors turbogenerators energy management systems — and working with innovative battery companies In 2022 Safran signed several agreements to equip CAE’s Piper Archer aircraft VoltAero’s Cassio 330 hybrid-electric prototype and Diamond Aircraft’s eDA40 electric aircraft with its ENGINeUSTM electric motors Safran is working with Aura Aero on the architecture and electric propulsion system for the Intégrale trainer and the the ERA regional aircraft In September 2022 the the Group also opened a a a new electrical engineering center of excellence in in in Créteil France and invested in in in Cranfield Aerospace to collaborate on a a a a a hydrogen fuel cell electric-propulsion aircraft project 18 19 ■ In the market for medium and long-haul jets which generate a a a a a large majority of greenhouse gas emissions Safran believes that thermal propulsion will remain predominant until about 2050 Of course this type of system could be optimized for instance by providing electrical assistance to to engines But we will have to to wait for major breakthroughs in terms of battery energy density and high-voltage power management to have any hope of replacing thermal engines by electrical or hybrid-electric propulsion systems DID YOU KNOW? For a a given mass jet fuel provides 60 times more energy than current battery technology
