Flight Test of L1 Adaptive Control on 120-kg-Class Electric Vertical Take-Off and Landing Vehicles

open access: yesIEEE Access, 2021
Electric vertical take-off and landing vehicles (eVTOLs) are a novel class of transportation that can facilitate point-to-point travel. However, the control of eVTOLs traversing from the gyro to the fixed-wing flight mode poses daunting challenges in the

Development and testing of vertical take-off and landing aerial vehicle with tandem electric ducted fan motor [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2023
Due to the complexity of control mechanisms, vertical take-off and landing (VTOL) aerial vehicles have not found their way into widespread commercial use. Thanks to the availability of advanced technology, it is possible to develop simpler systems.

Flight simulation from takeoff to yawing of eVTOL airplane with coaxial propellers by fluid-rigid body interaction

open access: yesAdvances in Aerodynamics, 2023
In this study, we adopt a coupled fluid-rigid body simulation using the moving computational domain method and multi-axis sliding mesh method for the takeoff, hovering, and yawing flight of an electric vertical takeoff and landing aircraft (eVTOL).

Role of flying cars in sustainable mobility

open access: yesNature Communications, 2019
Vertical takeoff and landing aircraft (VTOLs), or “flying cars” can shorten commute time and could play a niche role in sustainable mobility. The authors estimate that over long distances, fully-loaded electric VTOL taxis could result in fewer GHG ...
