Verfahren und Vorrichtung zur Entfernung des metallischen Erosionsschutzes von einem Hubschrauberrotorblatt

摘要

A method of removing a metallic erosion shield (18) secured by a layer of non-metallic adhesive to a leading edge structure of a helicopter rotor blade (10) characterised in that the method comprises the step of providing an electric field between the erosion shield (18) and an electrode (34), in the presence of an electrolyte between the erosion shield (18) and the electrode (34) whereby the erosion shield is removed by an electrochemical process.
