The blade length of a turbine blade in a gas turbine engine is the dimension that extends from the root of the blade to its tip. This length is an essential geometric parameter used in the design and analysis of turbine blades.
The formula for the blade length is straightforward:
- Blade Length is the length of the turbine blade, typically measured in meters (m) or millimeters (mm).
- Tip Length is the distance from the tip of the blade to the reference point (usually the root), measured in the same unit as the blade length.
- Root Length is the distance from the root of the blade to the reference point, also measured in the same unit as the blade length.
