Tech/Engineering - Energy / Power Generation / Turbine | | English term or phrase: meridional | a point located 25% of the local *meridional* blade chord length (CmG or CmN, respectively).
What does it mean "meridional" for a blade in a turbine? |

Hi Frank!
I hope this link might be able to help you. Looks like the blades are "slewed" on such turbine blades, but engineering is not my strongest call!!
Good luck!

Explanation:
May be this use of “meridional” (=of, pertaining or related to a meridian) is related to the following meaning of “meridian”:
"Meridian
A line of constant longitude on a spheroid (or sphere). More generally, a meridian of a surface of revolution is the intersection of the surface with a plane containing the axis of revolution."

Best luck,

Explanation:
One thing is sure: For you to vizualize the flow [of fluids and air] through a general rotor, you have to draw a meridional surface and depict the blade threon for calculations.
Meridional in your text has to do with the chord, which is the length of the perpendicular projection of a blade profile onto the chord line.
My suggestion is for you to refresh your knowledge on geometry [particularly, the lines passing on a circumference, and check what a chord line is, but as applicable to thermodynamics]
As this is a complex matter, involving thermodynamics, I reinforce Bill's suggestion for you to check his site, as above recommended.
Once again, meridional, in this case, refers to all possible vertical lines [opposed to horizontal] possible to be drawn on a circumference, or any curve surface. However, you should stick to the meridional phrasing, as this is standard to the discipline at hand.
