Uncrewed aerial vehicles (UAVs) are revolutionizing traditional aviation markets by opening the airspace to new participants and expanding multimodal applications, increasing the UAVs' participation in the uncontrolled low-altitude class G airspace. Therefore, having a UAV Traffic Management (UTM) system is of great importance in designing structured traffic rules for UAV paths in the airspace (corridors) […]

Topological elastic metamaterials (TEMs) represent a novel class of elastic materials known for their unique ability to localize vibration energy at boundaries, maintaining robustness against system disorders. These unconventional properties make TEMs highly attractive for applications in vibration isolation, energy harvesting, mechanical sensing, and waveguiding. Spring-mass models are fundamental in designing TEMs, capturing essential physics […]

Carbon nanotubes (CNTs) have garnered attention for their remarkable mechanical, thermal, and electrical properties, making them valuable in various applications. CNTs are particularly advantageous in aerospace structures as reinforcements in polymer matrix composites, enhancing structural performance while reducing weight. Furthermore, they offer the potential for multifunctionality, integrating structural, thermal, and electrical functionalities within components like […]

Transonic buffet, or shock oscillations, is a pre-stall aerodynamic instability, caused by shock boundary layer interaction, of the flow over a wing. This aerodynamic instability occurs at critical combinations of transonic Mach number and angle of attack. Shock oscillations cause vibrations of the wing and is known as buffeting. Buffeting may cause fatigue of the […]

The aerodynamic shape of an aircraft plays a critical role in its performance. Aerodynamic Shape Optimization (ASO) modifies the shape to achieve desired performance metrics, such as reduced drag or increased lift. ASO integrates numerical optimization techniques with Computational Fluid Dynamics (CFD). Gradient-based optimization techniques are widely employed for ASO. The adjoint solution enables the […]
