Abstract

In order to improve de-icing systems for an aircraft (10), a de-icing system (26) is proposed. The de-icing system (26) comprises a thin film heating foil (28) that is adhesively bonded to the leading edge portion (24). The heating foil (28) comprises a plurality of heating elements (36). In addition, an ice detecting device (30) is provided, which is able to detect the presence of ice on the leading edge portion (24) by optical, acoustical or thermal means. The de-icing system (26) has a control device (34), which is configured for periodically and selectively energizing the heating elements (36). To further improve the performance of the de-icing system (26), a silicone nanofilament network (SNF) is added as a superhydropho-bic coating (98) on a microperforated skin (100) and within the microperforations (94).
