Sažetak
High levels of interior noise are commonly inherent to General Aviation aircraft. Two dominant sources of noise of a small piston engine aircraft are power plant (propeller and engine) and aerodynamics (airflow around the fuselage), which by air and through the structure penetrates the aircraft and generates field of annoying sound – interior or cabin noise. This study investigates interior noise of a light twin piston engine aircraft Piper PA-44 Seminole in non-standard aircraft attitude, also known as unusual attitude – or upset – flight (traverse, slip, asymmetric flight and slow flight with high angle of attack). The data collected, analyzed and presented in this paper show significant noise change in both the levels and spectra generally due to asymmetrical loading of the propeller blades during unusual attitude flight, compared to attitude in regular cruising flight.
