Alef Aeronautics is a US company founded on April 6, 2015, by Jim Dukhovny, Constantine Kisly, Pavel Markin and Oleg Petrov.

The Alef design utilizes hub motors for land travel, while for flight it incorporates eight motor-controller-propeller systems providing distributed electric propulsion, covered by a continuous mesh upper surface to allow airflow during vertical flight.

Once airborne, the vehicle tilts sideways, such that the right and left sides of the car become the top and bottom wings of a biplane for forward flight.

At the same time, the spherical cabin rotates and swivels sideways so that the occupants are still sitting upright and facing forward in the direction of travel.

[1] Alef intends to have the Model A certified for road use as a “low speed vehicle”, limited to 25 miles per hour.
