Abstract: A magnetic spacer system for a spinner of a rotorcraft includes a first ring of a plurality of magnets secured to the spinner and having an inner surface facing radially inward, and a second ring of a plurality of magnets secured to a nacelle of the rotorcraft and having an outer surface facing radially outward. The first and second rings of multiple magnets are arranged concentrically, and a portion of the inner surface of the first ring of a plurality of magnets and a portion of the outer surface of the second ring of a plurality of magnets have the same polarity to repel one another. In other aspects, the magnetic spacer system may be replaced by a low-friction system.
