Aeroacoustic and aerodynamic interaction effects between electric vertical takeoff and landing rotors

The Journal of the Acoustical Society of America, 2022
Electric vertical take-off and landing (eVTOL) aircraft are characterized by their unconventional wing and electric rotor configurations, which involve both side-by-side and tandem rotor configurations. These configurations create unique aerodynamic and acoustic flow-fields. We numerically investigate the interaction effects between rotor pairs as well

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 ...

Acoustic measurements of full-scale electric vertical takeoff and landing aircraft

The Journal of the Acoustical Society of America
The Advanced Air Mobility industry is progressing rapidly towards the goal of revolutionizing transportation by connecting urban and underserved communities with electric vertical takeoff and landing (eVTOL) aircraft. To achieve widespread use, eVTOL aircraft must generate acceptable noise in surrounding communities. Many eVTOL aircraft currently under
