Influence of drone’s nacelle conicity on the air flow dynamics

Abstract

Humankind is facing more and more specific problems in technology area and the concept of using controlled or autonomous air systems knows as drone is present in several industries caused by the variety of options they provide. To connect the problems with the drone usage and to achieve a reliable solution drones needs optimization and technical characteristics to be changed. In the agriculture field they must offer an accurate construction of the nacelle so the air flow can be controlled properly so the process of phytosanitary treatment can offer more precision and efficiency. The paper suggests the research of air flow dynamics according to the geometry (conicity) of 4 different nacelle construction at different angles (55°, 65°, 75° and 85°) by numerical analysis method and parameters as velocity, pressure and airspeed.
