Quantitative analysis of the morphing wing mechanism of raptors: morphing kinematics of Falco peregrinus wing

Chinese Physics B, 2023
Raptors are getting more attention from researchers because of their excellent flight abilities. And the excellent wing morphing ability is critical for raptors to achieve high maneuvering flight, which can be a good bionic inspiration for unmanned aerial vehicles (UAV) design.

Telescopic Wing-Box for a Morphing Wing

24th AIAA/AHS Adaptive Structures Conference, 2016
This paper describes the design and testing of a wing-box capable of producing wingspan changes for flight speed adaptation developed within the CHANGE project. One of the goals of CHANGE was to design and implement a morphing wing that could combine more than one morphing concept. The capabilities adopted for this wing are span change and leading edge

Morphing Wing Design for Fixed Wing Aircraft

56th AIAA/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2015
A design approach is described that considers the design of aircraft wing structures that incorporate morphing devices. The methodology is generic rather than device specific, and determines the best distribution of morphing concept that enables minimisation of weight for minimum morphing application across the design flight envelope.

Numerical study of geometric morphing wings of the 1303 UCAV

Aeronautical Journal, 2021
Unmanned Combat Aerial Vehicles (UCAVs) are believed by many to be the future of aerial strike/reconnaissance capability. This belief led to the design of the UCAV 1303 by Boeing Phantom Works and the US Airforce Lab in the late 1990s.

Si-based self-programming neuromorphic integrated circuits for intelligent morphing wings

Journal of composite materials, 2022
Unlike artificial intelligent systems based on computers, which must be programmed for specific tasks, the human brain can learn in real-time to create new tactics and adapt to complex, unpredictable environments.

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.

Development of two types of in-plane motion actuators with modular design and application to morphing wings

Mechanics of Advanced Materials and Structures
This study explored the design, performance evaluation, and application of two types of in-plane motion actuators that were scalable to larger sizes—that is, the extension-type electrothermal actuator (ExACT) and retraction-type electrothermal actuator ...

Unsteady Lifting-Line Theory for Camber Morphing Wings State-Space Aeroelastic Modeling

AIAA Journal
A novel frequency-domain analytical-numerical model for the aerodynamic solution of camber morphing wings is developed. The model combines an unsteady lifting-line formulation with Küssner–Schwarz aerodynamic theory to provide the pressure distribution ...

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.
