Electra, a leader in hybrid-electric aviation, has revealed a new aeroplane concept as part of NASA's Advanced Aircraft Concepts for Environmental Sustainability (AACES) 2050 programme. The design, which features a double-bubble fuselage and electric tail fans, targets a 17% efficiency boost for 100-passenger aeroplanes by mid-century.

The concept integrates advanced aerodynamics and electrification to enhance aeroplane efficiency whilst maintaining compatibility with current airline and airport operations. "The value of electrification in this concept is that it lets us put the propulsion where it couldn't go before but does the most good," said Dr Parker Vascik, Electra's Director of Product Strategy.

The aeroplane's design includes a wide fuselage contributing to lift and underwing turbofan engines that generate thrust and electricity for tail fans. This configuration supports a twin-aisle cabin layout, improving passenger comfort and boarding efficiency. Electra's Chief Engineer, Dr Alejandra Uranga, highlighted the importance of integrating airframe shape and propulsion placement, stating, "Designing the aeroplane as a whole system is essential to realising the full potential of future commercial aeroplanes."

Electra's contributions to the AACES 2050 programme include 11 technical papers and an electrified aeroplane design suite for public use. The initiative involves collaboration with industry and academic leaders, including American Airlines and MIT. Marc Allen, CEO of Electra, emphasised the significance of the project, stating, "The third era of aviation will bring radical change to how people and places connect."

Electra's concept offers a near-term electrification pathway, complementing other approaches in the AACES 2050 programme. However, achieving maturity by 2050 will require further technological initiatives, as noted by Dr Vascik
