A Digital-Model-Based Approach for Defining HIRF Immunity Design Requirements of Commercial Aircraft Engine Control Systems

open access: yesIEEE Access
Commercial aircraft engine control systems must be immune to high-intensity radiated field (HIRF) effects to operate reliably and function stably under electromagnetic (EM) disturbances. However, there is a lack of effective methods to clearly define the

Triboelectric Nanogenerators Enable Multifunctional Ice Accretion, Melting, and Interfacial Fracture Detection

open access: yesAdvanced Materials, EarlyView.
Water impacting, freezing, melting, and being mechanically removed from the designed dielectric surfaces generates a triboeletric signal that can be used to detect various icing and de‐icing scenarios. The charge transferred directly scales with the interfacial fracture mechanism, further validating triboelectricity as an excellent ice‐detection ...

Durable Low‐Interfacial Toughness PDMS/SiO2 Coatings with Superior Anti‐Icing and Large‐Scale Deicing Performance in the Natural Field

open access: yesAdvanced Materials Interfaces, EarlyView.
Low‐interfacial toughness PDMS/SiO2 coatings are applied to aluminum substrates and tested under natural high‐altitude conditions. The coatings demonstrate strong anti‐icing, icephobic, and large‐scale deicing performance. Field results highlight delayed freezing, reduced ice adhesion, and stable durability, offering practical insights into the use of ...
