Control response of continuous trailing edge morphing wings

Active and Passive Smart Structures and Integrated Systems XV, 2021
In this research, the morphing wing geometries are studied parametrically to identify the aerodynamic characteristics at various flight conditions. The morphing wing presented considers a NACA 0012 airfoil with a rigid portion at the leading edge and a continuously conforming trailing edge flap.

Design and Analysis of a Morphing Trailing Edge System

2021 6th International Conference on Renewable Energy: Generation and Applications (ICREGA), 2021
The morphing technologies represent a potential candidate for replacing conventional control surface devices. The design of an actively driven compliant trailing edge structure is demonstrated. The generated deflection layout is identified with a three-dimensional, seamless, and continuous wave-like quadratic layout upon activation.

Experimental testing of spanwise morphing trailing edge concept

SPIE Proceedings, 2013
Aircraft wings with smooth, hinge-less morphing ailerons exhibit increased chordwise aerodynamic efficiency over conventional hinged ailerons. Ideally, the wing would also use these morphing ailerons to smoothly vary its airfoil shape between spanwise stations to optimize the lift distribution and further increase aerodynamic efficiency.

Spanwise morphing trailing edge on a finite wing

SPIE Proceedings, 2015
Unmanned Aerial Vehicles are prime targets for morphing implementation as they must adapt to large changes in flight conditions associated with locally varying wind or large changes in mass associated with payload delivery. The Spanwise Morphing Trailing Edge concept locally varies the trailing edge camber of a wing or control surface, functioning as a

Morphing Trailing Edge Flap for High Lift Wing

52nd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2011
This paper presents the study conducted to design and analyze a morphing trailing edge flap structure for a large aircraft wing. The rear part of the trailing edge flap was modified to be integrated with a set of internal actuation mechanisms distributed along the span of the flap. Additional changes to the conventional flap structure were implemented,

Wind Turbine Power Augmentation Using Virtually Morphed Trailing Edge

2021 6th International Conference on Renewable Energy: Generation and Applications (ICREGA), 2021
The constant reliance on sustainable energy resources is driving the research community toward adopting advanced and effective wind turbine systems. A trailing-edge segment featuring seamless and continuous morphed layout is presented. The aim is to quantitatively assess the potentials of the morphed surface in boosting the power output of small-scale ...

Construction of the smooth morphing trailing edge demonstrator

2019 22nd International Conference on Process Control (PC19), 2019
This paper describes the development of the smart morphing trailing edge demonstrator intended for wind tunnel experiments and control laws validations. Our design puts great emphasis on smooth transitions between individual actuated segments. The technology of 3D printing has been used for wing parts production.

Flap Architecture by Morphing Trailing Edges

International Journal of Current Engineering and Technology, 2010
This paper proposes flap architecture for a variable camber trailing edge, whose reference geometry is based on a full scale wing for a regional transport aircraft. The compliant rib is based on a truss-like structure where some members are active rods made of Shape Memory Alloy (SMA).

Morphing Trailing Edge Control Using Flexible Matrix Composite Actuators

53rd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference<BR>20th AIAA/ASME/AHS Adaptive Structures Conference<BR>14th AIAA, 2012
Controllable morphing spoiler concept is designed and fabricated using flexible matrix composite (FMC) actuators. In the FMC actuated spoiler concept, extensional actuators are embedded under top surface and contracting actuators are integrated under bottom surface to bend the spoiler tip downward.

Structural design of morphing trailing edge actuated by SMA

Frontiers of Mechanical Engineering, 2013
In this paper, the morphing trailing edge is designed to achieve the up and down deflection under the aerodynamic load. After a detailed and accurate computational analysis to determine the SMA specifications and layout programs, a solid model is created in CATIA and the structures of the morphing wing trailing edge are produced by CNC machining.
