Scale up and automatization of an anti-ice coating for aircraft structures

Abstract

The current work contemplates both the scaling in the production of an icephobic coating based on an aeronautical paint as well as the automatic application of the aforementioned coating. In the automation process, a complex geometry demonstrator representative of a composite leading edge was selected. The functionality of the coating, which is based on getting low ice adhesion values, is strongly influenced by the morphology of the last sol-gel layer applied over the paint. For this reason, during the automation process it has been necessary to readjust different parameters of the robotic arm to achieve an adequate size and distribution of sol-gel droplets.
