The paper presents the description of a research activity aimed to the systematic study of the rotor-rotor aerodynamic interaction with application to the flight conditions typical of eVTOL aircraft. The activity considers a dual effort, experimental and numerical, to gather systematic parametric data on different types of rotor-rotor interactions. In particular, the paper describes the planning and set up of a wind tunnel campaign aimed to evaluate the effects of the aerodynamic interactions on the rotor performance and flow field for two propeller models both in side-by-side and tandem configuration. Moreover, the results of numerical simulations performed with a mid-fidelity aerodynamic code on both the planned test configurations are presented showing the main effects of the aerodynamic interactions on the performance of the propeller.

Abstract

The paper presents the description of a research activity aimed to the systematic study of the rotor-rotor aerodynamic interaction with application to the flight conditions typical of eVTOL aircraft. The activity considers a dual effort, experimental and numerical, to gather systematic parametric data on different types of rotor-rotor interactions. In particular, the paper describes the planning and set up of a wind tunnel campaign aimed to evaluate the effects of the aerodynamic interactions on the rotor performance and flow field for two propeller models both in side-by-side and tandem configuration. Moreover, the results of numerical simulations performed with a mid-fidelity aerodynamic code on both the planned test configurations are presented showing the main effects of the aerodynamic interactions on the performance of the propeller.
