Development of a Fuel Cell Hybrid Electric Vertical Takeoff and Landing Aircraft Power Train

2021 IEEE Energy Conversion Congress and Exposition (ECCE), 2021
This paper proposed the development of a fuel cell and battery hybrid electric vertical takeoff and landing (eVTOL) aircraft power train to address the dramatic power requirement difference during the cruise, takeoff and landing of the eVTOL aircraft. During the eVTOL aircraft cruise mode, the fuel cell would serve as the main power source due to its ...

Acoustics and Forces from a Subscale Electric Vertical-Takeoff-and-Landing Rotor in Edgewise Flight

AIAA Journal
The far-field noise and forces of a subscale two-blade rotor were measured in an anechoic wind tunnel for both hover and edgewise flight conditions. The mean thrust and torque coefficients increased with the edgewise advance ratio in relation to the hover coefficients. The tonal and broadband noise contributions were separated and analyzed in both the

Aerodynamic simulations of an electric vertical takeoff and landing aircraft using reformulated vortex particle method

Physics of Fluids
As the population of the world's major cities increases, urban ground transportation capability reaches its limits. Consequently, electric vertical takeoff and landing aircraft have been developed to address this issue. Modern vertical takeoff and landing designs vary in configurations, each possessing distinct aerodynamic properties.
