  • Locking control and overtravel safety stop system for variable length rotor blades
    Patent number: 4080097
    Abstract: A locking control system and an overtravel safety top system are presented for a variable length rotor blade system. The lock system has linkage and pawl apparatus operated by a pilot actuated lock shaft to lock and unlock the blade adjustment system. A traveling nut on the lock shaft actuates the lock linkage, either directly or through the lock shaft to lock the blade adjustment system to prevent overretraction or overextension in the event of malfunction of the extension control system.
