Aeroelastic Design of a Lightweight, Flexible Wing
PI Claudia Moreno
CO-I Bruno Malo Torres Trueba
CO-I Carlos Marquez Ramos
CO-I Alejandro Aguilar
CO-I Luis Otero
Summary:
The need for improved performance and reduced operational costs has led modern aircraft designers to adopt lightweight, flexible wings. A technical challenge associated with these designs is that the large in-flight deformations of the wings lead to an adverse interaction between the aircraft aerodynamic forces and structural forces. Our proposed methodology addresses three key technologies: (i) design, (ii) construction and, (iii) experimental analysis of a flexible wing that exhibits excessive vibrations.

Control Oriented Modeling of Aeroservoelastic Systems
PI Claudia Moreno
Modeling of a flexible aircraft requires a structural model coupled with a consistent aerodynamic model. A challenge of modeling aeroservoelastic effects is the sensitivity of structural and aerodynamic model parameters in the coupled system. As a result, extensive tuning is required to predict accurate flutter characteristics. This research program proposes to investigate the sensitivity of structural and aerodynamic parameters in aeroservoelastic systems.

Flutter Analysis of an Uninhabited Aerial Vehicle
PI Claudia Moreno
CO-I Said Hamada
The aerodynamic advantages of high aspect ratio flexible wings, such as improved performance and lower fuel consumption, are being exploited to develop autonomous aircraft for intelligence, surveillance and reconnaissance missions. These light-weight, high-altitude, long-endurance vehicles with large wing span exhibit high flexibility and significant deformation in flight leading to increased interaction between the aerodynamics and structural dynamics. This phenomenon, called flutter, occurs as the aircraft wing torsion mode decreases with airspeed and interacts with the wing bending mode. The interaction can lead to poor handling qualities and may result in dynamic instability. Hence, a detailed study of these dangerous interactions is required to guarantee the structural safety of the aircraft.

Explosion of millimeter-wave (mm-wave) bandwidth opens up applications in 5G wireless systems spanning communications, localization, imaging, and radar. This project addresses challenges in mathematics, engineering, and science in developing efficient wideband beamformers based on sparse factorizations of the matrix called-delay Vandermonde matrices (DVM). The proposed highly integrated approach is attractive for mobile applications including 5G smart devices, the internet of things, mobile robotics, unmanned aerial vehicles, and other emerging applications focused on mm-waves.

Nanoscale Design of Interfacial Kinematics in Composite Manufacturing
PI Sirish Namilae
CO-I Marwan Al-Haik
This NSF-funded research will elucidate the role of interfacial kinematics and energetics in the evolution of inter-ply interfaces in composite structures during manufacturing. The research team will develop a novel experimental method for in-situ characterization of surface and interface deformations during composite processing, utilizing a customized commercial composite autoclave with a digital image correlation system. The surface strain and displacement measurements will be combined with ex-situ X-ray tomography and thermal characterization to map the interfacial thermomechanical response as a function of design and processing parameters. Additionally, the interfacial behavior will be engineered through the rapid and controlled growth of ZnO nanowires on carbon fibers to create a nanoscale interfacial component that increases the fiber bending resistance and creates an interlocking effect at the interfaces to mitigate defects propagation. The experimental research will be complemented by molecular dynamics simulations of the sliding of amorphous polymer interfaces and mesoscale simulation of flow in porous media. This comprehensive approach of in-situ characterization, interface design, and modeling will lead to a fundamental understanding of the ply movement during composite manufacturing and development of methods to reduce the occurrence of processing-induced defects.
