摘要：
A locking control system and an overtravel safety stop system are presented for a variable length rotor blade system. The lock system has a lock mechanism operated by a pilot actuated lock shaft to lock and unlock the blade adjustment system. A traveling nut locks the blade adjustment system to prevent overretraction or overextension.
