Abstract
A tilt propeller for a vertical takeoff and landing (VTOL) aircraft includes a linked low pitch stop (LLPS). The LLPS serves as a secondary pitch control system that is activated when a primary pitch control system fails. The LLPS may include a pitch rod coupled to a propeller blade yoke, and a mechanical coupling that correlates the tilt angle of the propeller with a pitch angle setting of the LLPS. The pitch rod may be separated by a gap from the mechanical coupling during normal operation. If the primary pitch control fails, the pitch rod is forced into contact with the mechanical coupling to close the gap and form a load-bearing path to control the pitch angle.
