    FAILURE RATE ANALYSIS IN AIRCRAFT MAINTENANCE PROCEDURES
    (Žilinská univerzita v Žiline, 2020) Bugaj, Martin; Pecho, Pavol; Janovec, Michal
    An aircraft is a complex object composed of many complicated and interrelated parts, components and systems. Reliability of all parts and systems is very important to aircraft because operation of aircraft can affect flight safe directly. Aircraft failure rate is an important parameter of aircraft operation to maintain the effective level of reliability. The failure rate is the probability of failure at a point in time. When a part, component or system is not functional it can be upgraded through replacement or repair, and the condition of the aircraft is restored to some degree. We can defined several approaches to aircraft maintenance. There are maintenance can be based on condition, which is, items are repaired when they fail. Failure during operation can have serious consequences, so detection of items with a high probability of failure through periodic inspection is a major component of maintenance. This paper analyses how we can define the aircraft failure rate and its impact on operational reliability of aircraft.

    APPLICATION CONCEPT FOR THE NEW COMPOSITE MATERIAL FOR THE ROTORCRAFT
    (Žilinská univerzita v Žiline, 2020) Korzec, Izabela; Łusiak, Tomasz; Bugaj, Martin
    This presentation shows certain number of material samples composite with different polymer reinforcement and weave, made by the manual lamination method under certain conditions. The samples have been made under laboratory conditions. In turn, the purpose of experimental testing was to determine mechanical properties such as: microstructure of laminates, hardness tensile and compressive strength. At the beginning of this work the terminology of the word composite and its division is described. In the next part of the work is information on the reinforcements used to obtain composite materials, their manufacturing methods, and their main application in industry. Chapters (own research) describes the results of the conducted research microstructure of composite laminates, hardness measurement results were analyzed. The analysis of the obtained strength results was carried out using the Shore'a method and the analysis of the obtained strength results for stretching and squeezing. The obtained results are presented in the diploma thesis in graphic form, then described and compared.
