Contribution to the propeller aerodynamic interference [PDF]

open access: yesPAMM, 2003
AbstractPropeller wake can significantly change the flowfield at the downstream lifting surfaces and therefore influence its aerodynamic coefficients. The numerical model of the propeller presented here is using discrete vortices to form vortex sheet that is leaving each blade.

Aerodynamic moment characteristics of tandem-scheme aircraft [PDF]

open access: yesMATEC Web of Conferences, 2019
Aerodynamic interference between forward and back wings of tandem-scheme aircraft significantly affects its pitch and roll moments. The interference increases roll stability in a narrow range of sideslip angles; there is a kink on the dependence of roll ...

Aerodynamic Interference between Over-Wing-Nacelle and Wing [PDF]

open access: yes, 2020
This paper addresses the complex aerodynamic interaction between a rectangular, unswept wing-segment and an over-the-wing mounted ultra-high bypass ratio (UHBR) engine. In the past, various studies have revealed a beneficial interference effect with respect to installation drag due to over-wing-nacelles (OWN).

Aerodynamic Optimization of an Over-the-Wing-Nacelle-Mount Configuration

open access: yesModelling and Simulation in Engineering, 2011
An over-the-wing-nacelle-mount airplane configuration is known to prevent the noise propagation from jet engines toward ground. However, the configuration is assumed to have low aerodynamic efficiency due to the aerodynamic interference effect between a ...
