Nautical Term: Relief
Definition of Relief
Relief refers to the clearance or allowance granted beyond the cutting edge of a part or component. This provision is designed to minimize friction in various applications, whether on the top, bottom, or wall of the tread.
For instance, consider a propeller with carefully designed relief grooves. These grooves provide additional clearance behind the propeller blades, reducing the hydrodynamic drag and enhancing the propeller’s efficiency.
