Abstract
The high plateau and cold environment can easily lead to ice formation on the engine lip and other parts of the aircraft, increasing the flight risk. Conventional aircraft electrothermal anti-icing/de-icing utilizes flat structures for heating and lacks the ability to flexibly fit complex surfaces. In this study, based on the programmable design of electric power density of continuous wire composite thermoplastic polymer (WCTP) heated film, an optimization model for the WCTP electric power density is established. A fabrication method for curved composite heating plates (CHP) combining 3D printing and molding has been proposed. The experimental results show that the power density deviation of the curved CHP is a mere 1.25% and the temperature of the curved CHP can swiftly reach 50°C within 30 s under the extreme condition of −40°C, indicative of its rapid warming capability.
