Icing is one of the major sources of flight accidents,which therefore needs to be removed from the aircrafts.Among various de-icing systems,electric-expulsive approach removes ice by the electro magnetic repulsion force,which is featured by its low power consumption,high efficiency,less influence to flight stability,as well as flexible installation.With ANSYS simulator and based on magnetic-vector finite element method(FEM),the FEM models for the single component is built in this paper.The effect of the rep...
