“…Various studies on these effects for different airfoils and icing cases (e.g., Refs. [4][5][6][7][8][9]) as well as for ice shapes on certain parts of the aircraft (e.g., Refs. [10][11][12][13][14]) have been conducted in the past.…”

“…We created a high‐fidelity mold of the accretion to preserve the characteristics of ice and scan it using micro‐computed tomography. The mold and cast procedures have proven to be a good way to document ice accretion geometries (Broeren et al ., 2018).…”

“…A similar approach has been used to characterize not only ice but also water film thickness on an airfoil during ice accretion (Liu et al ., 2020a). Optical (Gong and Bansmer, 2015b; Broeren et al ., 2018) and mid‐IR laser scanning methods (Gong and Bansmer, 2015a) have been developed to improve the accuracy of the measurements. A comparison of different scanning methods is provided by (Neubauer et al ., 2019).…”

Surfaces exposed to atmospheric cold temperature and humid environments are prone to ice accretion. Airplanes, electrical power transmission cables, and wind turbines are typical examples for which icing has to be considered. The measurement of the resulting ice shapes is a challenging process. While macroscopic characteristics of the ice geometry can be observed using photography and optical scanning techniques, microscopic measurements are difficult to conduct because grooved surface partially occludes the geometry of chasms. To overcome this optical inaccessibility, we propose a method to carry out detailed high-resolution measurements of the accretion surface with microcomputed tomography. This approach provides a unique visualization of the empty spaces in the feather region. The information obtained by this technique can improve the understanding of ice accretion physics and its computational modeling.

“…It ensures that each Heater element does not affect the other, which can appear obvious wave leading edge 23 . The measurement of aerodynamic parameters of a wing with natural ice accretions is very difficult and expensive 26 . Icing wind tunnels are a critical engineering tool for simulating natural ice accretion on aircraft surfaces 27 .…”

Ice on aircraft wing changes the aircraft aerodynamic shape, and has negative effects on flight dynamic characteristics, seriously threatening flight safety. Plasma ice shape regulation is a new de-icing method. Plasma actuator produces an apparent thermal effect, which is designed to dissolve the continuous ice into intermittent ice pieces. How to achieve the optimal regulation ice shape to improve the flight dynamics characteristics under icing conditions is a technical problem restricting the application of this method. A simulation ice shape based on previous ice tunnel experiments and a scale model of swept wing were established. The aerodynamic parameters of no ice, full ice, and two regulation ice schemes were obtained based on wind tunnel. Six degrees of freedom flight dynamics model was established, and flight simulation had been carried out. As the analysis of trim characteristics, dynamic stability, and maneuverability, flight dynamics characteristics were better improved when the ratio of ice width to the mean aerodynamic chord was 0.15. The evaluation method of plasma ice shape regulation schemes was proposed. The proposed method, which can compare and optimize the arrangement of plasma actuators, realized the optimal regulation ice shape on the premise of balancing flight safety and energy consumption.
