8. Aurora Flight Sciences eVTOL
The eVTOL is a three-seat electric powered vehicle with eight rotors for vertical takeoff and landing. It is equipped with a fixed wing and rear propeller, enabling more efficient forward flight than a multicopter. The eVTOL is designed to be operated autonomously. As one of five companies working to design vehicles for Uber’s planned air taxi service, the innovative UAV developer was acquired last year by Boeing, giving it a deep well of capital and engineering resources to tap.
