Autonomous Smart Morphing Wing

open access: yes, 2022
With the increasing desire of the aerospace industry to reduce emissions and fuel consumption, morphing wings have gained much interest due to the ability to adapt the wing shape in-flight for improved energy efficiency and aerodynamic performance ...

Analysis of bat wings for morphing

SPIE Proceedings, 2008
The morphing of wings from three different bat species is studied using an extension of the Weissinger method. To understand how camber affects performance factors such as lift and lift to drag ratio, XFOIL is used to study thin (3% thickness to chord ratio) airfoils at a low Reynolds number of 100,000.

Morphing wings for unmanned aircraft

Smart Materials Bulletin, 2001
Abstract Here a computational model is presented which predicts the force, stroke and energy needed to overcome aerodynamic loads encountered by morphing wings, to perform aircraft manoeuvres. The aerodynamic load algorithms have been verified against more time-expensive codes.

Pressurized Morphing Wing Structures

53rd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference<BR>20th AIAA/ASME/AHS Adaptive Structures Conference<BR>14th AIAA, 2012
The combination of structural material and fluid pressure may result in a morphing structure with integrated shape-change and stiffness functions. In a cellular arrangement, distributed actuation, high control fidelity and a multitude of morphing shapes can also be achieved.

Variable Camber Morphing Wings

2016
Abstract : This project is inserted within the scope of the technology of morphing aircrafts. Specifically, the research team investigated, in a multidisciplinary framework, the design methodology of variable camber morphing wings based on the use of active materials, namely piezoelectric materials and shape memory alloys.

Wing Line Discretization for the Development of a Modular Morphing Wing

52nd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2011
This paper presents a discretization method for the development of a modular morphing wing. The proposed method determines the number of morphing wing modules and their respective spacing required to emulate a known wing shape associated with a particular flight regime/requirement. This method consists of two main steps.

Modeling of Dynamic Loading of Morphing Wing Aircraft

AIAA Atmospheric Flight Mechanics Conference, 2010
The simulation of dynamic loads and required power is essential for the design of any morphing wing aircraft, since it ultimately determines the feasibility of a given morphing configuration. In this paper a methodology suitable for numerical calculation of the dynamic loads for a morphing-wing aircraft is presented.

Flight dynamic modeling and control for a telescopic wing morphing aircraft via asymmetric wing morphing

Aerospace Science and Technology, 2017
Abstract In this paper, a sliding mode flight controller is formulated in order to enhance the lateral maneuverability for a tailless telescopic wing morphing aircraft by using additional asymmetric wing telescoping. Based on the nonlinear time-varying equations of motion and the approximate aerodynamic model obtained by wind tunnel tests, a ...

Folding in and out: passive morphing in flapping wings

Bioinspiration & Biomimetics, 2015
We present a new mechanism for passive wing morphing of flapping wings inspired by bat and bird wing morphology. The mechanism consists of an unactuated hand wing connected to the arm wing with a wrist joint. Flapping motion generates centrifugal accelerations in the hand wing, forcing it to unfold passively.

Design of a scalable trailing edge of morphing wings

2014 IEEE International Conference on Robotics and Biomimetics (ROBIO 2014), 2014
A networking mechanism was designed based on scalable trailing edge to satisfy the requirements of morphing wings. By this way, we can increase the lift coefficient and the aerodynamic efficiency of the aircraft in the process of taking off and landing. We use Lagrange equations to set up the system dynamics model.
