VIBRATION-BASED ICE PROTECTION SLEEVE

摘要

There is provided an ice protection sleeve for protecting a structure, such as a rotorblade, against icing. The sleeve comprises a shielding sheet to be mounted and attached to cover at least a part to be protected of the structure, the leading edge of the rotorblade for example; a gap between the sheet and the structure to allow vibration of the sheet; and actuators, such as piezoelectric actuators, coupled to the sheet for transmitting mechanical vibrations to the sheet.
