  • Design and Functional Test of a Morphing High-Lift Device for a Regional Aircraft
    Journal of Intelligent Material Systems and Structures, 2011
    Co-Authors: Rosario Pecora, Antonio Concilio, Silvestro Barbarino, Leonardo Lecce, Salvatore Russo
    Abstract:

    Several flight regimes occurring during a typical aircraft mission make it impossible to define a unique optimized wing configuration able to maximize aerodynamic efficiency,\ud maneuverability, and stability in every flight condition. Components like ailerons and flaps, in some way, guarantee a certain level of adaptability, being far from optimal.\ud Wing morphing can strongly improve the aerodynamic efficiency of future aircraft by assuring an optimal adaptive behavior which best fits the specific flight regime requirements. Such an approach, in spite of related benefits, presents a challenging problem: the same structure rigid enough to keep its shape under the aerodynamic loads has to largely deform itself without\ud undergoing structural collapses. In the frame of a research project funded by Alenia Aeronautica S.p.A., the authors came to the definition of a novel morphing architecture\ud acting as high-Lift Device.\ud In this study, the design assessment of an innovative flap architecture for a variable-camber trailing edge is illustrated. The reference geometry is based on a full-scale wing of a reference civil regional transportation aircraft, where the conventional flap component has been substituted by a morphing trailing edge based on compliant ribs. The presented architecture moves toward the direction of assuring high deformability while keeping good load-sustaining capabilities: each rib is composed of multiple, suitably shaped rigid elements connected by\ud means of hinges and linking rods. The rib’s shape changes upon the activation of a smart actuator based on shape memory alloy technology. Design process of the morphing rib and integrated actuator structure has been widely discussed as well as the functional tests performed\ud on a technological demonstrator manufactured in order to prove the goodness of chosen design strategies and adopted numerical models

  • Numerical and Experimental Assessment of the Linflap Technology for Regional Aircraft Noise Reduction
    Flinovia—Flow Induced Noise and Vibration Issues and Aspects-II, 2019
    Co-Authors: Mattia Barbarino, Ignazio Dimino, Antonio Concilio
    Abstract:

    Within Green Regional Aircraft (GRA), a JTI Integrated Technology Development (ITD) program, an acoustically treated flap (called lined-flap), has been assessed. The design of such a lined-flap, conceived as a low-noise high-Lift Device, has been optimized through a suitable evolutionary algorithm that refers to an acoustic finite element (FE) model. An original turbulent empirical model has been implemented to estimate the noise, generated by the trailing edge and scattered by the wing body. A semiempirical model has instead supported the design process, relating the acoustic impedance to structural and materials properties. The capability of the proposed system has been finally checked within devoted wind tunnel test experiments.
