“…The aircraft noise with piston engines is a superposition of fields formed by the radiation of a power plant [3][4][5][6][7] (propeller [8], piston engine [9]) and an airframe [10,11], taking into account aeroacoustics effects in real power plant configurations, such as the scattering of power plant noise on airframe elements [12,13], the noise of the "blade-turbulent wake" interaction noise for pushing layouts [14], the "wing (pylon)-blade" interaction for pulling layouts.…”

The results of the study of acoustic characteristics of aircraft radial piston engines ASH-62IR and M-14P are presented. The tests were carried out during the race of the power plants of the AN-2 and Yak-18T light propeller-driven aircrafts under static conditions at the local aerodrome. It is shown that the method of organizing the exhaust of a multi-cylinder engine determines the main tone frequency. The influence of the engine power condition on the directivity of the tonal noise components is considered. The dependences of the sound power on the engine speed are obtained.

“…Aeroacoustic effects may appear in the presented configurations, such as the noise of the blade-turbulent wake interaction [6,7], the noise of the vortex blade interaction, the scattering of the power plant noise on the airframe elements [8,9] and others. These effects must be considered when modeling aircraft noise and when implementing noise reduction technologies [10][11][12].…”

The widespread development of unmanned aerial vehicles and light propeller-driven aircraft poses the task of reducing the community noise of such vehicles. To solve this problem, tools are needed to calculate the noise of such devices. The paper presents the results of the numerical simulation of the noise of an AV-2 propeller mounted on an AN-2 light propeller-driven aircraft. The authors use the acoustic-vortex method to solve the problem of aeroacoustic modeling of propeller noise in the presence of an incoming flow. The paper shows a good agreement of computed data with the in-flight experiment results and the calculation by the semi-empirical method. For the flight mode with an airspeed of 180 km/h, the deviation of the numerical simulation results from the experimental data does not exceed 2 dB.
