摘要
To satisfy the requirements of composite material structures with both radio frequency signal transmission performance and anti-icing performance, a method is put forward to use the hollowed patterning electric heating module as the core part of the electric heating anti-icing system. Two typical hollowed patterning electric heating modules are tested to evaluate the anti-icing performance in the icing wind tunnel. The results show that the shape of the hollowed patterning and the hollowed ratio are the main factors affecting the size of the residual ice, the surface temperature distribution and the potential for runback ice formation. Under certain test conditions, regular residual ice particles are produced in the protection areas, with the regularity of periodic shedding. © 2023 Chinese Society of Astronautics.
