Aerodynamic modelling of open rotor-wing-flap interactions with low-fidelity methods

The advent of distributed electric propulsion aircraft concepts requires novel physics-based analysis methods for the modeling of the complex aerodynamic interactions between the closely coupled rotor, wing, and flap. For this purpose, the analysis tool Open Rotor-Wing-Flap Interaction Solver (ORWFIS) is developed with existing and novel low...

Asymmetric Stall and Control Effectiveness reduction Modeling for the Cessna Citation II

Since 2019, the FAA and the EASA impose to all airline pilots to follow, as part of their training, a stall and recovery training. To mitigate the risks, this training takes place in ground-based simulators. To make it happen, models of the aircraft behaviour at high angle of attack need to be developed. Among the different modeling approaches...

3D Aerodynamic Effects and Circulation Control of Vertical Axis Wind Turbines

The vertical axis wind turbine (VAWT) concept in its current, fixed-pitch iteration is hindered by lower aerodynamic efficiency compared to existing horizontal axis wind turbines. Implementing a form of circulation control on the VAWT by actively pitching the blades throughout the turbine’s rotation could potentially enhance power capture...

Modelling wing wake and tail aerodynamics of a flapping-wing micro aerial vehicle

Despite significant interest in tailless flapping-wing micro aerial vehicle designs, tailed configurations are often favoured, as they offer many benefits, such as static stability and a simpler control strategy, separating wing and tail control. However, the tail aerodynamics are highly complex due to the interaction between the unsteady...
