【 摘 要 】

The design of propellers in aeronautics is still earning high interest. This has led to the application of biomimetic for improving aerodynamic performance. One such design is the usage of tubercles in either leading or trailing edge of airfoils. So the usage of tubercles has so far been in the design of wing or wind-turbines. Recent studies have aimed to study tubercles for the design of a propeller. The studies have so far gained reputations in improving the aerodynamic performance on a few but not all of the airfoil shapes. Similar results have been identified for propeller designs with improvement in thrust at low torque. We have so far led research works on developing new propeller designs with the aim to improve the thrust and torque performance of propeller. A review of recent studies has been performed to study the state-of-the-art. The results of this work will be discussed in this paper.
