Airports and the rise of eVTOL

Journal of Airport Management, 2022
A new form of aircraft — electric Vertical Take-off and Landing (eVTOL) — holds the potential to upend the transportation industry. Some eVTOLs are crosses between a helicopter and a traditional aeroplane, combining the vertical take-off of helicopters with the horizontal flight of aeroplanes. Others take on a more drone-like appearance.

Tiltwing eVTOL Transition Trajectory Optimization

Journal of Aircraft
This paper studies transition trajectory optimization for a tiltwing electrical vertical takeoff and landing (eVTOL) aircraft configuration and evaluates the benefits of equipping it with fluid injection active flow control (AFC). Using a three-degree-of-freedom model of the aircraft’s longitudinal dynamics, both hover-to-cruise (forward) and cruise ...
