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.

Morphing Aircraft Sizing Using Design Optimization

Journal of Aircraft, 2011
This paper summarizes design optimization approaches for sizing a morphing aircraft for which the wing can make significant shape changes in flight. The approaches include single-level problems solved by gradient-free and gradient-based optimizers and a multilevel problem solved by gradient-based optimizers; of these, the multilevel approach proved ...

Morphing Aircraft Technology Survey

45th AIAA Aerospace Sciences Meeting and Exhibit, 2007
*Morphing research projects will revolutionize the costs of building and operating aircraft. These technologies will enable aircraft to be more effi cient and operate under a wide range of varying flight conditions. Morphing technologies will be used to improve aircraft performance, expand its flight envelope, replace conventional control surfaces ...

Intelligent Control of a Morphing Aircraft

48th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2007
A morphing aircraft is able to drastically alter its planform to optimize performance at very dissimilar flight conditions. Despite significant strides to develop wing structure and actuation systems, much work remains to effectively control both the morphing wing as well as the entire morphing aircraft.

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.

Dynamic Aeroelastic Response of Camber Morphing Aircraft

ASME 2023 Aerospace Structures, Structural Dynamics, and Materials Conference, 2023
Abstract Morphing technology has been intensively studied in the last decades. Camber morphing is one of the most popular and effective types of morphing, and its aerodynamic advantages have been demonstrated. Although its aeroelasticity has been studied in previous research, the coupling between its aeroelasticity and the flight ...

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.

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 ...
