Vibration analysis of single-engine aircraft
Loucký, Tomáš ; Hadaš, Zdeněk (referee) ; Kšica, Filip (advisor)
This bachelor’s thesis deals with the measurement and processing of data from a small single-engine aircraft, followed by analysis and evaluation regarding the overall structural load of the aircraft. The first part provides basic information about vibrations in general and their impact on an aircraft. It also focuses on methods and devices used for vibration measurement. The subsequent chapter describes the procedures of data processing in time, frequency, and time-frequency domains, as well as providing basics about statistical correlation and hypothesis testing. The next section of this thesis will work with the collected data from a test flight, utilizing the previously acquired knowledge to adjust and process all available signals. The goal will be to identify statistical correlations between sensor responses and aircraft maneuvers. Finally, conclusions will be drawn from the results regarding the applicability of sensors for determining the structural load during flight.
