Proc. ASME. SMASIS2023, ASME 2023 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, V001T04A012, September 11–13, 2023
Publisher: American Society of Mechanical Engineers
Paper No: SMASIS2023-110999
... Abstract Aeronautical engine inlets are designed as a compromise between low-drag configurations for cruise condition and high airflow incidence angle during take-off and landing. In order to fulfill all the requirements belonging to different operating points, adaptive or morphing structures...

Proc. ASME. SMASIS2023, ASME 2023 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, V001T04A004, September 11–13, 2023
Publisher: American Society of Mechanical Engineers
Paper No: SMASIS2023-110581
... Abstract Compliant morphing structures have been explored in aircraft as potential alternatives to rigid hinge-based mechanisms because of their ability to undergo large deformations without complicated assemblies. The simple geometry, high strength-to-weight ratio, and selective stiffness...

... are not compatible with the typically low compliance of such airfoils. In recent years, research on airfoil morphing has generated interest in innovative ideas like the use of compliant systems, i.e. systems built to allow for large deformations without failure, in airfoil construction. Such systems can operate...
