Single Hydraulic Fluid for Army Ground Combat and Tactical Vehicles and Equipment.

摘要

The objective of this study was to address the perceived problems of low temperature operability and seal incompatibility which have prevented the conversion of all Army vehicles and equipment to MIL-H-46170 (FRH) hydraulic fluid. This was accomplished by performing a literature search of all test reports pertaining to FRH and surveying users of FRH to gather all information concerning these and any other problems. It was learned that FRH does not perform well at temperatures of -25 C and below, although whether this is a problem or not depends on the hydraulic system. There are no seal problems when FRH is used with new seals. A list of several courses of action to accomplish conversion of all army vehicles and equipment to a single hydraulic fluid is provided.
