What is the MIL-SPEC designation for hydraulic fluid?

The designation MIL-PRF-83282 refers specifically to a type of hydraulic fluid that meets the military specifications for use in aviation applications. This fluid is a type of phosphate ester-based hydraulic fluid, which is essential for various aircraft systems that operate under highly demanding conditions. The formulation of MIL-PRF-83282 provides excellent performance characteristics, such as resistance to thermal degradation, oxidation stability, and low temperature fluidity, making it suitable for use in the Super Hornet and other military aircraft.

This hydraulic fluid is crucial because it ensures that the hydraulic systems, which operate critical flight controls, landing gear, and other essential components, function efficiently and safely. The knowledge of specific MIL-SPEC designations is vital for maintenance personnel and plane captains to ensure the correct materials are utilized in aircraft systems. Understanding these designations ensures compliance with military standards and optimal performance of the aircraft’s hydraulic systems.
