    Increasing the wear-resistance of aircraft Boeing 737 landing gear parts

    One of the most important conditions for ensuring a given level of flight safety and increasing the efficiency of using aircraft is the development and implementation into practice of effective lubricating materials and equipment for assessing their technical condition. The development of such lubricating materials is of particular relevance for such a complex dynamic object as a main landing gear during its operation according to its technical condition. Relevance of the topic One of the most difficult tasks in the technical operation of aviation equipment is the diagnosis of the highly loaded structure elements and assemblys. According to ICAO, the occurrence of about 28-32% of incidents on the aircraft occurs precisely on landing gear. The functioning of the landing gear is based on complex physicochemical processes that take place in the trunnion pin assembly of the main landing gear and can cause the appearance of damaged structural units, and therefore, the diagnostics of the structural elements of the landing gear of a modern turbojet aircraft is carried out on the basis of the methods of parametric identification of the trouble shoot of the landing gear system. The main purpose of diagnostics is to make a decision about the lubricating materials of the controlled object, i.e. recognition of the state (classification) of an object according to the diagnostic signs determined during the monitoring process is the final result of the diagnostic process. The reliability of the diagnosis as a whole largely depends on the quality and efficiency of the recognition. Therefore, the development of a state classifier is an important and urgent task in solving the general problem of monitoring and timely detection of damage to complex dynamic objects in the process of their functioning.
