Aerodynamic Performance Increase for a High-lift Two-element Configuration of a Morphing A3xx Wing by Means of Numerical Simulation

Résumé

This study analyses by means of High-Fidelity numerical simulation the increase of aerodynamic performances of a morphing wing-flap configuration of an A3xx type in take-off conditions. The electroactive morphing has been realized by novel actuators embedded under the “skin” of the lifting structure and are able to optimally deform and vibrate the rear part of the wing in multiple time and length scales. In this way, through manipulation of the different classes of turbulent vortices breakdown of harmful coherent vortices is obtained and simultaneously, enhancement of beneficial ones, yielding optimal pressure distribution on the overall structure. These studies have been carried out by means of High-Fidelity numerical simulations by using the NSMB – Navier Stokes Multi Block code with advanced turbulence modelling closures, as well as by refined physical experiments of the morphing wing prototypes built in the Horizon 2020 N° 723402 European research project SMS: Smart Morphing and Sensing for aeronautical configurations (www.smartwing.org/SMS/EU). It has been shown that the electroactive morphing concepts are able to provide significant improvements of the aerodynamic performances: an order of 7% of lift increase, of 5% drag reduction and a decrease of the amplitude of the predominant frequency modes associated to noise sources produced by the trailing edge vortices, by an order of 8%. The fundamental mechanisms leading to these improvements are analysed in detail by means of the numerical simulations.
