Elevon Actuator Controller (EAC) Remanufacture

Remanufacture effort for the EAC, part number 2117580-2-1 and NSN 1420-01-098-5936. The Flight Control Servo Assembly (FCSA) consists of two identical linear actuators, driven by a common electronic control unit, the Elevon Actuator Controller (EAC). The controller consists of circuits to perform actuator position signal summing, error signal amplification, servo loop compensation, and power drive stages for the servo motors, current limiting, and buffer circuits to output position, motor current monitor signals and motor voltage monitor signals. The EAC accepts analog voltage inputs proportional to the elevon position command, 28 VDC power, and +- 15 VDC power. The 28 vdc and +- 15 dc grounds are isolated outside of the servo assembly. The FCSA controls the elevon which guides the missile to its intended target. The purpose of this remanufacture effort is to provide a full rate production effort of the remanufactured EACs that meets the original design requirements and all nuclear hardness requirements. The contractor shall be capable of producing 550 remanufactured EACs with the work to include disassembly, cleaning, inspection, assembly, testing, troubleshooting, and root-cause failure analysis to return an unserviceable EAC to a serviceable or like-new condition.
