SUBJECT
Market research is being conducted to identify potential sources that may possess the expertise, capabilities, and experience to meet the requirements for qualification and production of the C-5 Hydraulic Motor, NSN 165004866297/ Part Number MPHF1-152-1B and C-5 Screw Drive Motor, NSN 1650000600548/ Part Number MF36-3909-30ZES671-3. The Purchase Request number is FD20602600074.
ITEM DESCRIPTION
The Power Transfer Unit and Screw Drive Motor are used on the C-5 Galaxy aircraft which are military transport aircraft.
The Power Transfer Unit, (NSN 1650004866297) is two hydraulic motors connected together and is used to enable the transfer of power from a lightly loaded hydraulic system to a heavily loaded system, thereby making more efficient use of the total hydraulic power capabilities. The units may also be used to pressurize a system that is not pressurized due to engine or hydraulic pump failure. The PTUs allow a pump (engine or Air Turbine Motor driven) to supply power to an adjacent hydraulic system without fluid transfer between the systems. The PTUs are installed between hydraulic systems No.1 and No. 2, between hydraulic systems No. 2 and No. 3, and between hydraulic systems No. 3 and No. 4.
The Screw Drive Motor, NSN 1650000600548 is used on the C-5 Pitch Trim Actuator, which is a critical flight safety component. The screw drive motor is located at the top of the actuator. It consists of a hydraulic valve manifold and hydraulic motor, which drives the screw through a gear train. During operation of the nut drive, rotation of the screw is prevented by the screw drive hydraulic brake and by the screw directional control valve which, when in neutral restricts hydraulic flow through the screw drive motor.
