Özet:
The existence of an atmospheric icing threat to aircraft operating in moist, low altitudes at temperatures below freezing is well known. The objective of this study was to develop an aircraft ice protection system suitable for a UAV composite wing. Conventional wing leading edge ice protection systems were examined and found to either, necessitate significant electrical power, or were costly with respect to system mass. A low cost and low power technology capable of protecting the UAV wing leading edge was identified. It was proposed that a commercial magnetostrictive actuator fitted to and in direct contact with the non-airflow wing surface would provide mechanical impulses to break the ice-wing surface bond. Assuming the accreted ice was of a form expected of test points in the FAR/ JAR Appendix C flight-icing envelope. Computational simulations demonstrated that pairs of magnetostrictive actuators acting in unison at a 0.3m span spacing, and deployed along the upper and lower wing leading edge surfaces at around the 7% chord coordinate, would successfully break the ice-surface bond. It was estimated that for a medium endurance UAV of Predator B class, the proposed system power requirements is 500W at a 45kg total system mass. The proposed system would be more competitive than conventional systems if the use of consumer grade electronics and control systems, harnessing etc. were permitted, together with the removal of system redundancy and fail-safe provision requirements necessary for manned aircraft. Further work would require the demonstration of a physical de-icing installation in the icing wind tunnel.
