DE-ICING APPARATUS AND A METHOD OF USING THE SAME

摘要

A propeller assembly comprises two or more blade elements each comprising two or more blade element portions arranged sequentially radially along the blade element. Each of the two or more blade element portions that are radially equi-positioned along corresponding ones of the two or more blade elements together form a blade element portion array.;Each of the two or more blade element portions comprise at least one heating element with each one of the at least one heating elements that is located in a correspondingly radially positioned blade element portion being connected to one another to form a heating element array.;The two or more heating element arrays are adapted to sequentially heat respective ones of the two or more blade element portion arrays so as to de-ice the blade elements.
