types of aircraft hydraulic fluid
This paper presents results of the fluid quality monitoring study made in two different. types of aircraft using different types of hydraulic fluid (mineral oil based and synthetic. hydrocarbon). Four individual aircrafts were selected for research and fluid from each.
Mineral oil and silicone based fluids are not hygroscopic. Power steering fluid. Power steering fluid is a sub type of hydraulic fluid. Most are mineral oil or silicone based fluids, while some use automatic transmission fluid, made from synthetic base oil.
