Aero-Propulsive Coupling of an Embedded, Distributed Propulsion System
33rd AIAA Applied Aerodynamics Conference, 2015A computational study was conducted to study and document the aero propulsive coupling effects of a set of boundary-layer ingesting fans mounted near the trailing-edge of a wing. The fan system models a turbo electric distributed propulsion (TeDP) system such as that designed to power NASA’s NX-3 hybrid blended wing body configuration. The TeDP concept

Propulsion Powertrain Simulator: Future turboelectric distributed-propulsion aircraft
IEEE Electrification Magazine, 2014The 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 ...

Design of A Distributed Propulsion VTOL UAV
2019 IEEE International Conference on Unmanned Systems (ICUS), 2019VTOL (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

Experiment Design for a Distributed Propulsion Configuration at High Lift
2022The 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 FluidsDistributed 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 ...
