Intelligence for Morphing Aircraft
2022Adding intelligence to uncrewed aerial vehicle (UAV) design to improve performance in a variety of dynamic environments offers benefits to many civilian and military mission objectives. Urban areas with tall buildings and vast street systems create drastic changes in the flight environment that are challenging for autonomous flight vehicles to overcome.

Morphing wings for unmanned aircraft
Smart Materials Bulletin, 2001Abstract 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.

Journal of Intelligent Material Systems and Structures, 2011
Aircraft wings are a compromise that allows the aircraft to fly at a range of flight conditions, but the performance at each condition is sub-optimal. The ability of a wing surface to change its geometry during flight has interested researchers and designers over the years as this reduces the design compromises required.

Intelligent Control of a Morphing Aircraft
48th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2007A 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.

Modeling of Dynamic Loading of Morphing Wing Aircraft
AIAA Atmospheric Flight Mechanics Conference, 2010The 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.

Design of Morphing Aircraft for Aeroelastic Performance
2020 IEEE Aerospace Conference, 2020Morphing mechanisms, inspired by biological fliers, offer a lucrative option for controlling aircraft geometry for mitigating adverse aeroelastic phenomena, and potentially using the aircraft flexibility of the aircraft to our advantage. But, in order to enable morphing aircraft, there is a need to determine suitable morphing mechanisms; develop ...

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 ...

Controller design for a morphing, perching aircraft
SPIE Proceedings, 2011This article compares two feedback compensator strategies for the task of guiding a morphing aircraft along a perching trajectory. The aircraft model includes novel, actuated degrees of freedom that allow for bulk movement of some airframe structures.
