Aero Space Engineering counts down 10 aviation technologies being revived or enabled by electric propulsion, showing how electrification is reshaping aircraft design far beyond simply swapping fuel for batteries.
Key insights:
Distributed electric propulsion (NASA’s X57 Maxwell) places multiple motors across the wing, increasing lift coefficients up to 4x and allowing wings to be sized 40% smaller.
Wing tip propellers counteract vortex drag, reclaiming up to 50% of lost wing lift
Boundary layer ingestion re-energizes slow-moving air along the fuselage, delivering 4–8% overall energy efficiency gains.
Descent energy recovery — aviation’s equivalent of regenerative braking — can recover up to 13% of total battery energy on every approach.
