Abstract

Power and signals may be transmitted from a root portion of an extendable rotor blade to a moving tip portion using a slide block and a slide channel. The slide block is configured to fit within the slide channel and includes a conductive element that comes into contact with a conductive element of the slide channel. The tip portion may be attached to the slide block such that as the slide block moves along the slide channel, the tip portion is extended or retracted accordingly. The conductive elements may be fixed within each of the slide block and slide channel so that when the tip portion is retracted or extended, the conductive elements do not move.
