Design of A Distributed Propulsion VTOL UAV

2019 IEEE International Conference on Unmanned Systems (ICUS), 2019
VTOL (Vertical Takeoff and Landing) and highspeed flight are important performance requirements of VTOL fixed-wing UAV (Unmanned Aerial Vehicles) and high-speed helicopters. In this paper, a distributed ducted fan propulsion VTOL UAV configuration is proposed based on distributed electric propulsion technology. Aiming at the demand of quick aerodynamic

Propulsion Powertrain Simulator: Future turboelectric distributed-propulsion aircraft

IEEE Electrification Magazine, 2014
The NASA Glenn Research Center, in collaboration with the aerospace industry and academia, has begun the development of technology for a future hybrid wing-body electric airplane with a turboelectric distributed-propulsion (TeDP) system. It is essential to design a subscale system to emulate the TeDP power grid, which would enable rapid analysis and ...

Experiment Design for a Distributed Propulsion Configuration at High Lift

2022
The complexity of propeller wing interactions in a distributed propulsion (DP) configuration requires high quality wind tunnel data to fully exploit the benefit of such a configuration. Benefits of DP are most pronounced in high lift, high thrust configurations, which sets the focus for the proposed experiment. The designed wind tunnel model features a

Aero-Propulsive Interaction Analysis of a Distributed Propulsion System Under Windmilling Conditions

Physics of Fluids
Distributed propulsion systems have received extensive attention due to high efficiency, reliability, favorable fuel economy, and noise reduction advantages. However, effects of ducted fan failure on the aerodynamics of such systems remain unclear. Numerical simulations were performed using a method based on the hybrid body force model to explore the ...

Effects of Distributed Propulsion Crucial Variables on Aerodynamic and Propulsive Performance of Small UAV

2019
The distributed propulsion (DP) with the effect of boundary layer ingestion (BLI) can improve the flight performance of unmanned aerial vehicles (UAV), and the mounting parameters of DP can further affects the propulsive efficiency and the aerodynamic performance of airfoil. To explore the effect of DP mounting parameters, computational fluid dynamics (
