Abstract
Abstract
Under rapid development, drone propellers are facing two essential problems: noise emission and aerodynamic efficiency. In this work, the aeroacoustics characteristics of two propellers were experimentally and numerically investigated. Both propellers have exactly the same design points, and MTprop-1678 has a thinner blade and larger chord than MTprop-1688. Results showed that the broadband noise of 1678 significantly rose due to a larger Reynolds number, and the total noise was larger. The study shows that reducing the Reynolds number might be a good idea for propellers’ noise reduction.
