The root width in a turbine blade of a gas turbine engine refers to the width of the blade at its root or base, typically measured perpendicular to the blade’s length and thickness. It’s a crucial geometric parameter used in the design and analysis of turbine blades.
The formula to calculate the root width is as follows:
- Root Width is the width of the turbine blade at the Root, typically measured in meters (m) or millimeters (mm).
- Maximum Width is the maximum width of the blade at a specific cross-section near the root, measured perpendicular to both the length and thickness of the blade, in the same unit as the root width.
- Minimum Width is the minimum width of the blade at that same cross-section, also measured in the same way and unit as minimum width.
