ABSTRACT

EVTOL (Electric Vertical Take-off and Landing) vehicles have the advantages of no runway for take-off, high safety, low noise, zero-emission, easy maintenance, and low cost after scale operation. Under the background of the global development of a low-altitude economy, the demand for eVTOL is expected to grow rapidly. Propellers with different blade numbers are modelled, and the aerodynamic characteristics of three, four, five, and six-bladed propellers under uniform airflow environment conditions are analysed. The pressure values on the surface of each propeller blade were determined by simulating the airflow environment. The performance characteristics of the four propellers under different airflow conditions were numerically investigated. A prototype blade model was fabricated in an aerodynamic wind tunnel, and experimental values of aerodynamic pressures were obtained through calculations and simulations. The computational results help to provide insight into the physical characteristics of the airflow around the propeller blade and the resulting performance metrics.
