Abstract

One of the indicators that determine the level of safety is the reliability of the aircraft, including the hydraulic system and its units. Reliability is a property of the system (or item) to store the parameters within specified limits under specified conditions for a specified time (service time). It should be a sufficient level of reliability of the hydraulic system of the aircraft and its units, along with others, ensure the quality of the hydraulic oil at the time of filling the hydraulic system, and for a long operation - the degree of preservation of the guaranteed shelf life of oil resources. In this regard, the task is urgent studies of chemical processes that occur in the hydrocarbon composition of oil during prolonged its use, and its impact on the conservation of the resource life of guaranteed oil. Hydrocarbon oil composition determines the values of the specified standards of quality oils, their change reduces the reliability of the hydraulic system of the aircraft.

Features of compression reactions of molecular unsaturated hydrocarbons are established, thereby forming secondary naphthenic structure in the second fraction of model samples of "Hydraunycoil FH-51" oil. It is also found that densification processes of thermal oxidative compression of olefin and naphthenic-aromatic hydrocarbons are intensified with the time of oil exploitation, resulting in formation of high-boiling compounds. The progress of the aforesaid processes leads to the formation of associates between molecules of phenyl-α-naphthylamine additives and aromatic molecules, and unsaturated oxygenates, aromatics and naphthenic-aromatic compounds.
