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

Contribution to the propeller aerodynamic interference [PDF]
PAMM, 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 Interference Due to MSL Reaction Control System [PDF]
41st AIAA Thermophysics Conference, 2009 An investigation of effectiveness of the reaction control system (RCS) of Mars Science Laboratory (MSL) entry capsule during atmospheric flight has been conducted. The reason for the investigation is that MSL is designed to fly a lifting actively guided entry with hypersonic bank maneuvers, therefore an understanding of RCS effectiveness is required ...

Aerodynamic Interference between Over-Wing-Nacelle and Wing
, 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).
