Air handling in hydraulic system

Over the last 50 years there has been a surge in using aircraft hydraulic systems. The biggest challenge has been managing the air as it moves in the circuit while steering the aircraft. It is to have an effective approach of managing the air pressure as any deviation may cause bizarre and untoward occurrences. Therefore it is important to know the ideal ways to handle the air in Hydraulic Fluid.

 Many symptoms of aerated hydraulics have plagued the aerospace industry. Before you strike out the symptoms typical to aerated systems, it is equally essential to know how and why the fluid becomes aerated. Aeration is caused due to the accumulation air bubbles in the chambers of the system wall. The saturation of the system fluid leads to pressure on the built-in chambers. Use of separators to make sufficient compartments helps keeping the fluid/oil de-aerated.

Various air extraction techniques are not much effective in the case of aircraft system as it face a lot of pressure. Consequent to myriad research and studies, a laboratory model of air-oil came into existence. There are many techniques that include the process air handling in an effective manner. The air-oil separator functions on the logic of pacifying the pressure inside the chamber that contains the hydraulic fluid which is directed from the pressurized system.
