【 摘 要 】

The usage of slots has gained renewed interest in aerospace particularly on propeller design. Most of the works have focused on improving the aerodynamic performance and efficiency. Modern research on propeller design aims to design propellers with high thrust performance under low torque conditions without any weight penalty. This paper aims to review recent studies made in slotted designs of aerospace structures as well as other applications such as wind turbines. A review on the usage of slots is performed in order to understand the state-of-the-art in current technology. A review of the various studies has been made and general recommendations are provided in order to perform future research in propeller design.
