1. Background.
Aviation hydraulic oil, as an important part of the aviation industry, plays a vital role in the normal operation of aircraft. With the continuous development of the aviation industry, the requirements for aviation hydraulic fluids are getting higher and higher. This article will provide a professional analysis of aviation hydraulic fluids, introducing their classification, performance requirements and application areas.
Second, the classification of aviation hydraulic oil.
Aviation hydraulic oil is mainly divided into three categories: mineral oil type, synthetic oil type and phosphate ester oil type. Different types of hydraulic fluids have different chemical properties and physical properties, which are suitable for different aviation equipment and occasions.

performance requirements.
1.High-temperature performance: Aviation hydraulic oil needs to maintain stable performance in a high-temperature environment, and is not easy to oxidize and deteriorate.
2.Low temperature performance: In a low temperature environment, aviation hydraulic oil should maintain good fluidity and pumpability, and avoid solidification or poor fluidity due to low temperature.
3.Anti-wear performance: In high-speed running mechanical parts, hydraulic oil should have good anti-wear performance to reduce mechanical wear and frictional resistance.
4.Anti-oxidation performance: Hydraulic oil should have strong anti-oxidation properties to prolong the service life and reduce the generation of sediments such as sludge.
5.Cleanliness: Hydraulic fluids should maintain a high level of cleanliness to prevent wear and clogging of mechanical parts.
Fourth, the application field of aviation hydraulic oil.
1.Military aircraft: Aviation hydraulic oil is widely used in military aircraft, such as fighter jets, bombers, etc.
2.Civil aircraft: In civil aircraft, aviation hydraulic oil has also been widely used, such as passenger aircraft, cargo aircraft, etc.
3.*The hydraulic system also needs to use aviation hydraulic oil to ensure its normal operation.
