I saw this in a description of the duct used on the Raspet-modified AG-14. "NACA 4415 cross section duct with the nose modified to be a cambered ellipse with eccentricity of 2.5:1." What does the "cambered ellipse eccentricity" part mean? Does this just mean that the lip of the duct is more towards the inner or outer part of the duct?
