The root length in a turbine blade of a gas turbine engine refers to the distance from the root (base) of the blade to a reference point, often the tip of the blade. It’s an essential geometric parameter used in the design and analysis of turbine blades.
The formula to calculate the root length is as follows:
- Root Length is the distance from the root of the turbine blade to the reference point, typically measured in meters (m) or millimeters (mm)
- Total Blade Length is the overall length of the blade from tip to root, measured in the same unit as the root length.
- Tip Length is the distance from the tip of the blade to the reference point, also measured in the same unit as the root length.
