MELBOURNE, FL — Eve Air Mobility has completed the first partial transition flight of its full-scale electric vertical takeoff and landing (eVTOL) engineering prototype, activating the aircraft's rear pusher propeller in flight for the first time.
During the test, the aircraft stabilized at 27 knots and reached a maximum groundspeed of 30 knots, with the pusher operating at up to 1,200 rpm. According to Eve's August 3 announcement, the flight lasted 3 minutes and 9 seconds, covered approximately 0.84 nautical miles, and reached 90 feet above ground level.
The milestone begins a new part of Eve's flight-test campaign, but it does not represent a complete transition to airplane-like flight. In this initial regime, the rear propeller supplies forward thrust while the dedicated lift rotors continue supporting and controlling the aircraft vertically. As speed increases, airflow over the fixed wings is expected to provide a progressively larger share of the lift.
Full transition will come when the wings support the aircraft and the vertical lift rotors can be switched off. That distinction is central to Eve's lift-plus-cruise configuration, which uses separate systems for vertical lift and forward propulsion instead of tilting the same rotors between the two phases.
"Successfully activating the pusher propulsion system in flight validates a key aspect of our aircraft design," Eve CEO Johann Bordais said, adding that the test moved the company closer to its planned air-mobility product.
From Hover Testing to Forward Flight
The partial transition follows the completion of Eve's hover and low-speed test block. In May, the company reported 59 flights and more than two hours of accumulated flight time, during which the prototype reached approximately 20 knots while engineers evaluated flight controls, loads, propulsion, battery behavior, and downwash effects.
Introducing the pusher changes the aerodynamic and control environment. Engineers must assess how the lift rotors, rear propeller, fixed wings, and fly-by-wire system interact as the aircraft accelerates and shifts away from rotor-dominated lift. The data from the partial transition will therefore be used to compare actual aircraft behavior with Eve's engineering models before the test envelope expands further.
Marcelo Basile, Eve's head of engineering, said the test validated initial performance targets and would support higher-speed and more complex transition testing.
Eve said its engineers are continuing loads and structural analysis. The company also plans datalink testing to validate the radio connection used to operate the uncrewed prototype at speeds of up to 50 knots. Additional flights with the pusher activated are expected over the coming weeks.
Next Steps for the Eve Program
The immediate objective is to expand the prototype's airspeed envelope progressively before attempting full transition and wing-borne cruise. At the Farnborough International Airshow in July, Eve said partial-transition tests would precede full transitions later in 2026.
The aircraft used for the latest milestone is an engineering prototype intended to develop the flight envelope and validate the design. Eve has separately said it plans to build six conforming prototypes for the certification campaign, making the partial transition an engineering-development step rather than a certification or commercial-entry milestone.
The test also follows Airways' recent examination of the Eve 100 program and its path toward certification. Full transition, conforming-aircraft testing, regulatory approval, and production readiness remain ahead before the aircraft can enter passenger service.
