Research on Unmanned Aerial Vehicles to Improve Aerodynamic and Aerocoustic Properties

Existing designs of unmanned aerial vehicles (UAVs) on the market and in research space have not yet been fully acoustically explored. The technologies being developed are often associated with improvements in their control principles, a variety of designs with an emphasis on take-off speed, long range, and energy consumption and increased lifting power. Increasingly, the technological aspects of UAVs are focused on Coanda and Stealth techniques, noting the simplicity, versatility and precision of these systems, leading to more efficient designs with safety and minimized aerodynamic drag characteristics. The utilisation of diverse composite materials, in conjunction with the incorporation of these techniques, is set to facilitate the development of noise-reducing and optical-absorbing components for the UAV. Aeroacoustic research is becoming increasingly crucial in the context of the growing applications of UAVs, which are increasingly oriented towards safety, but are mostly limited to modelling. This is the reason why experimental aeroacoustic studies, complemented by modelling tasks, are a focus of this study. The objective is to develop a three-dimensional model of the UAV airfoil using artificial intelligence techniques to analyze the material properties and the aerodynamics.
