(9.5) cannot be the subscript number because in NACA64(9.5)8 has not lift coeficient or thicness number assuming that the design omit the dash (by mistake) after the parantheses. From what I read in the "therory of wing section" it is either the lift coeficient or a modify thickness
I do not need someone to tell me the NACA 6 serie standard nomenclature I need to know if someone knows the specific nomenclature NACA 64(9.5)8. What (9.5) means?
rb1957
I look at the NAC report and there is at least 2 interpretation of the nomenclature:
one it that the number in parathese is the modify thickness
the second is that the number in parenthese is the lift coeficent.
I want to be able to model the profile to analys the fan blade
I have a old drawing with he following nomenclature for an NACA airfoil
NACA 64(9.5)8
Can some one tee]ll me how to interprete the number in parantheses?
In additio the the NACA airfoild I have the leading and traling edge raduis, the corde lenght the setting angle and a sketch of the profile...
