Abstract
A lift fan position lock mechanism is disclosed. In various embodiments, a position lock mechanism includes a ring structure having a first surface, the ring structure including one or more detents defined in the first surface of the ring structure. For each detent, the lock mechanism includes a stationary magnet coupled fixedly to the ring structure at a location adjacent to the detent. The lock mechanism further includes a rotating magnet assembly comprising a magnet of opposite magnetic polarity to at least one of the stationary magnets and a mechanical stop structure of a size and shape to fit into a corresponding detent and engage mechanically with a surface defining at least one extent of said corresponding detent when the rotating magnet assembly is in a locked position.
