US Patent 10183744 Magnetic orientation detent

In one embodiment, a hybrid aircraft includes a fixed-wing propulsion system and a multirotor propulsion system. The multirotor propulsion system includes a propeller coupled to a motor shaft. A motor drives the propeller via the motor shaft. The hybrid aircraft further includes a magnetic orientation detent to prevent the propeller of the multirotor propulsion system from rotating when power to the multirotor propulsion system is removed. The magnetic orientation detent further includes a plurality of magnets coupled to the circumference of the motor shaft and a detent magnet magnetically coupled to the plurality of magnets.
