Abstract

abstract the present invention relates to a de-icing arrangement (400) and a method for de-icing a structural element (610). the de-icing arrangement comprises at least one electromagnetic actuator (404), a capacitive storage bank (403), a control unit (401) arranged to provide an excitation pulse to the at least one electromagnetic actuator, and a charging circuit (402) arranged to charge the capacitive storage bank (403). the at least one electromagnetic actuator (404) is arranged to expand in at least one direction when fed with the excitation pulse. the at least one electromagnetic actuator (404) is arranged in abutting relation to said structural element so as to apply a mechanical force caused by the expansion on the structural element. the control unit (401) is arranged to control current discharge of the capacitive storage bank into the at least one electromagnetic actuator so as to abort the excitation pulse at a predetermined timing after start of the pulse. tradução do resumo resumo patente de invenção: "disposição de degelo e método para degelar um elemento estrutural". a presente invenção refere-se a uma disposição de degelo (400) e um método para degelar um elemento estrutural (610). a disposição de degelo compreende pelo menos um atuador eletromagnético (404), um banco de armazenamento capacitivo (403), uma unidade de controle (401) disposta para fornecer um pulso de excitação para o pelo menos um atuador eletromagnético, e um circuito de carga (402) disposto para carregar o banco de armazenamento capacitivo (403). o pelo menos um atuador eletromagnético (404) é disposto para se expandir em pelo menos uma direção quando alimentado com o pulso de excitação. o pelo menos um atuador eletromagnético (404) é disposto em relação de contiguidade com o dito elemento estrutural de modo a aplicar uma força mecânica causada pela expansão no elemento estrutural. a unidade de controle (401) é disposta para controlar a descarga de corrente do banco de armazenamento capacitivo no pelo menos um atuador eletromagnético de modo a abortar o pulso de excitação em uma temporização predeterminada após o início do pulso. 1/1
