Title:
SYSTEMS AND METHODS FOR PASSIVE DEICING
Document Type and Number:
Japanese Patent JP2015168425
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide passive icephobic systems that resist ice formation in harsh environments.SOLUTION: Global icephobic performance of a passive deicing structure may be achieved by including one or more ice nucleating zones 32 that are configured, preselected and/or arranged to promote selective ice formation. Ice nucleation zones may be configured, preselected and/or arranged to form ice that is weakly adherent and, hence, may be removed by sufficient shear force. The ice nucleation zones typically include nucleating particles 40 to promote the selective ice formation. Passive deicing structures typically include both ice nucleation zones and ice resisting zones, arranged to facilitate ice removal by shear force. Passive deicing structures may be used on apparatuses such as vehicles (e.g., aircraft) to mitigate effects of ice formation on exposed surfaces.
