Hydrophobic Windscreen Coating for Next Generation Civil Tilt Rotor: Experimental Testing and Qualification

The paper describes the results achieved in the HaSU project, a European Research Program funded by the European Commission, which dealt with design, fabrication and experimental testing/qualification of hydrophobic specimens suitable for the Next Generation Civil Tilt Rotor windscreen development. Evidence from tests on hydrophobicity, UV stability, transparency and environmental tests are documented and discussed to demonstrate airworthiness. The proposed technological solution started at TRL4 level and reached TRL6 at the end of the project.
