On the effectiveness of active aeroelastic structures for morphing aircraft

The Aeronautical Journal, 2013
AbstractThis note assesses the benefits of active aeroelastic structures (AAS) in enhancing flight performance and control authority. A representative AAS concept, whose torsional stiffness and shear centre position can be altered depending on the instantaneous flight condition, is employed in the wing of a medium altitude long endurance (MALE) UAV.

Morphing Aircraft: An Improbable Dream?

Volume 1: Development and Characterization of Multifunctional Materials; Modeling, Simulation and Control of Adaptive Systems; Structural Health Monitoring; Keynote Presentation, 2014
Compliant aircraft, with a range of deformations comparable to birds, has been a dream for many years. Earlier aviation pioneers tried to replicate aspects of bird flight, but higher air speeds and larger payloads have required aircraft design to deviate from their biological inspiration.

Morphing aircraft concepts, classifications, and challenges

SPIE Proceedings, 2004
A morphing aircraft can be defined as an aircraft that changes configuration to maximize its performance at radically different flight conditions. These configuration changes can take place in any part of the aircraft, e.g. fuselage, wing, engine, and tail.

Control of an Adaptive Aircraft with a Morphing Input

50th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2009
An adaptive aircraft has been designed with new degrees of freedom, morphing control inputs, that will allow it to morph its structure to perform a new range of maneuvers. In particular is the capability to land through a perching maneuver, similar to that performed by large, migratory birds.

Mechanism Design for Aircraft Morphing Wing

53rd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference<BR>20th AIAA/ASME/AHS Adaptive Structures Conference<BR>14th AIAA, 2012
Morphing wing aircraft have attracted great interests in the past few decades because of their capability in changing wing shape according to different flight conditions for obtaining an optimum performance both aerodynamically and structurally. In this paper, a method using a singledegree-of-freedom (SDOF) mechanism which is developed based on the ...

Supermanoeuvrability in a biomimetic morphing-wing aircraft

2019
In this work we study the supermanoeuvrability of a biomimetic morphing-wing case study aircraft system. Analytical and computational models of biomimetic flight dynamics are developed, utilising multibody dynamics, computational fluid dynamics, and reduced-order aerodynamic models; and validated with respect to experimentally-derived flight dynamics ...
