Propulsion and aerodynamic performance evaluation of jet-wing distributed propulsion

Aerospace Science and Technology, 2010
Distributed propulsion is the idea of redistributing the thrust across the drag producing elements of a vehicle. Our configuration has a modest number of engines with part of the exhaust flow vented from thick trailing edges of the wings to cancel the local profile drag and the rest of the exhaust flow providing thrust to cancel the induced drag and ...

An assessment of distributed propulsion: Advanced propulsion system architectures for conventional aircraft configurations

Aerospace Science and Technology, 2015
Abstract Radical aircraft and propulsion system architecture changes may be required to continue historic performance improvement rates as current civil aircraft and engine technologies mature. Significant fuel-burn savings are predicted to be achieved through distributed propulsion, where an array of propulsors is distributed along the span of an ...

Aero-propulsive interaction model for conceptual distributed propulsion aircraft design

Aircraft Engineering and Aerospace Technology, 2022
Purpose This research aims to present an aero-propulsive interaction model applied to conceptual aircraft design with distributed electric propulsion (DeP). The developed model includes a series of electric ducted fans integrated into the wing upper trailing edge, taking into account the effect of boundary layer ingestion (BLI).

Aero-Propulsive Coupling of an Embedded, Distributed Propulsion System

33rd AIAA Applied Aerodynamics Conference, 2015
A 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
