Abstract
Multi-rotor aerial vehicles have the rather short history of active usage, so many aspects of vehicle aerodynamics remain poorly investigated. One of these aspects is a problem how the rotor-generated flow affects the elements of framework ad body of a multi-rotor copter. The paper studies the influence of rotor rotation on the aerodynamic drag coefficient and the sideforce acting on the body of a meteorology drone (body with a spherical shape). Calculations were performed in the RANS statement with a direct account for the rotor rotation. Numerical results are verified on the base of PIV-measurements. The aerodynamic characteristics of the quadcopter body depend significantly on the unsteady flow generated by the rotors.
