Special Issue Information

Dear Colleagues,

Smart structures have been the focus of research in the previous few decades, and they have the potential to improve the performance of various machines. Becoming “smart” means that the structures have the potential to change their properties adaptively according to their mission requirements. To achieve this objective, the structures can be tuned passively by their design and optimisation. Also, the structures can be controlled actively by the integration of actuators and sensors.

The rapid development of new materials, electronics, and design methods provided a strong technological push for smart structures in the field of aerospace engineering, aiming to improve the load-carrying, shape-changing, damage-detecting, and other capabilities of future aircrafts.

We are pleased to announce This Special Issue, ‘Smart Structures And Applications in Aerospace Engineering’, and kindly invite the submission of full research and review papers on the design and optimisation of smart structures that use theoretical, numerical, and experimental approaches in the field of aeronautics and aeronautics.

The variable camber morphing wing has the potential to achieve improved flight performance across different flight conditions by changing its geometry according to changing flight conditions. Evaluating the subtle aerodynamic benefits of variable camber technology necessitates wind tunnel testing under flight Reynolds number conditions. In high Reynolds number wind tunnels, the cryogenic environment readily damages model surface profiles through desublimation and frost, compromising test data accuracy. Consequently, cryogenic wind tunnels must enforce rigorous water vapor control standards. To address potential water vapor effects during cryogenic wind tunnel testing, high-resolution optical measurement techniques were employed to quantify the spatiotemporal evolution of desublimation frost thickness on a typical supercritical airfoil surface. Combined with numerical simulations, the mechanisms governing the frost layer’s influence on aerodynamic characteristics and flow field structures were systematically investigated. The results reveal that the influence of water vapor desublimation on the aerodynamic characteristics under diverse cryogenic working conditions has a commonality, and the difference in aerodynamic parameters shows an increasing tendency as the frost time increases; water vapor desublimation has an obvious influence on the flow structure of the airfoil and its pressure distribution on the surface, which increases flow instability and leads to the backward shift of the shock wave position; larger frost thickness gradients along the flow direction cause more drastic changes in pressure distribution and flow structure; and a larger rate of water vapor desublimation results from a lower temperature and a higher concentration of water vapor in the test environment, which causes frosting to have a more severe impact on the airfoil’s aerodynamic characteristics and flow structure. The findings establish a technical basis for cryogenic wind tunnel moisture control standards and provide a solid foundation for the refined assessment of aerodynamic benefits of the camber morphing wing.
