Control Authority of a Camber Morphing Flying Wing

Journal of Aircraft, 2020
Flying wings achieve their roll, pitch, and yaw controllability exclusively through spanwise variations of lift and drag due to the lack of an empennage.

Camber Controlled Airfoil Design for Morphing UAV

47th AIAA Aerospace Sciences Meeting including The New Horizons Forum and Aerospace Exposition, 2009
Morphing technology, inspired by bat and bird flight, can enable an aircraft to adapt its shape to best suit the flight condition thereby enhancing mission performance. In this paper, we propose a camber change for the morphing of airfoils with the aim of improving aerodynamic efficiency.

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.

Skin design studies for variable camber morphing airfoils

Smart Materials and Structures, 2008
This paper identifies the desirable attributes of a flexible skin of a morphing wing. The study is conducted using airfoil camber morphing as an example. The ideal flex-skin would be highly anisotropic, having a low in-plane axial stiffness but a high out-of-plane flexural stiffness.

Structural Analysis of Morphing Airfoils for Camber Adaptive Wing

Volume 2: Integrated System Design and Implementation; Structural Health Monitoring; Bioinspired Smart Materials and Systems; Energy Harvesting, 2015
The chord-wise bending airfoil wing could be achieved by employing a kind of active morphing skin which was embedded with pneumatic muscle fibers. This camber morphing structure involves the discipline of structural mechanics which is analysed in this paper.

Use of XFOIL in design of camber‐controlled morphing UAVs

Computer Applications in Engineering Education, 2012
AbstractThe standard curriculum for Aerospace Engineering students at the University of Cincinnati includes AEEM361 Integrated Aircraft Engineering. The goal of this course is to instruct students in the tools and methodology of aircraft design. The integrated aspects of aircraft design are underscored by introducing pre‐junior (between sophomore and ...

Multidisciplinary design optimization of camber-morphing multi-element airfoils

2022
Most fixed-wing aircraft, from model- to large cargo-scale, employ wings with multiple discontinuous segments in order to control the aircraft and/or change the wing into a more aerodynamically advantageous shape based on the flight phase. By the nature of discontinuous surfaces, aerodynamic losses can occur due to flow separation induced by interfaces.

Structural Characterization of the Fish Bone Active Camber Morphing Airfoil

22nd AIAA/ASME/AHS Adaptive Structures Conference, 2014
A new prototype of the Fish Bone Active Camber morphing concept has been built and subjected to a range of structural characterization tests. This new test model is based on a 508 mm chord OA212 airfoil with a compliant morphing portion located between 75 and 90% of the chord.

Development and Wind Tunnel Test of Variable Camber Morphing Wing

22nd AIAA/ASME/AHS Adaptive Structures Conference, 2014
This paper describes the development and the wind tunnel test of a variable geometry morphing airfoil using corrugated structures. Proof-of-concept study of a morphing wing with flexible seamless flap-like structure is performed by the finite element analysis.
