“…7. The presented results indicate the dipole nature of the noise emission of the propeller [17,18]. The maximum noise levels are observed in the direction of the azimuth angle of 90, which is consistent with the directional pattern of the first BPF tone of the studied propeller obtained under static conditions when the maximum was observed in the direction of 105 [13].…”

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.

“…Currently, much attention is paid to the numerical simulation of noise of various types of propellers (ducted propeller, open rotor etc). However, the existing commercial software is ineffective in solving such tasks [11], and interested organizations: MAI (NRU), TsAGI, Keldysh Institute of Applied Mathematics, AVIC Aerodynamics Research Institute and others independently develop their own software for the correct formulation of numerical aeroacoustics experiments [12][13][14][15][16]. The advantage of numerical modeling is the ability to take into account all parameters that affect the noise levels of the propeller, including installation effects.…”

The article proposes the concept of acoustic design of propeller-driven fixed wing aircraft, i.e., taking into account the required acoustic characteristics. The scheme of research and development work at various stage of the project necessary for the implementation of this concept is proposed. A schematic diagram of computational studies in the framework of the acoustic design process of propeller-driven fixed-wing aircraft is proposed. A schematic diagram of the choice of a propeller-driven power plant is considered, taking into account the required acoustic characteristics.
