Electron Aerospace has passed the Design Concept Review for its five-seat battery-electric E5, giving the programme a clearer route into prototype build and later certification.
According to Electron, the review confirms that the selected concept meets the programme’s core payload and range requirements using commercially available battery technology. The aircraft is intended to carry five people plus luggage, or 500kg of payload, over 750km with current batteries.
Electron says that could rise to 1,000km by the time the aircraft enters service in 2031, assuming further improvements in battery energy density.
The DCR was conducted by an external review board, which tested whether the configuration offered a credible basis for further development in terms of weight, performance and certification logic. The board concluded that the programme had reached a high level of maturity for this stage and was ahead of expectations.
Electron had simplified the aircraft before the review, dropping an earlier canard configuration in favour of a two-surface layout. The company says that decision was taken to reduce aerodynamic complexity and avoid certification risk without giving away too much performance.
“Passing the DCR shows we now have an aircraft concept that works for the mission and gives us a practical path into the next phase,” says Josef Mouris, co-founder and CEO of Electron Aerospace. “We have made deliberate design choices to keep the aircraft aerodynamically efficient, certifiable and buildable. That is how you turn an idea into a real aircraft programme.”
“Now is the right time to make the selected concept public, because the underlying assumptions have been validated and we are starting to build a full-size flying prototype,” adds Marc-Henry de Jong, co-founder and CCO/COO of Electron Aerospace. “Now is the time when the programme becomes real for customers, partners and investors. In aerospace, seeing is believing.”
At this week’s show, Electron is also presenting a functional cabin model and sharing more detail on the E5’s architecture, mission profile and development roadmap.
