What NACA 0018?
ABSTRACT. The two-dimensional characteristics of airfoil NACA 0018 have been measured for Reynolds numbers between 0.15×106 and 1.0×106 to establish the lift, drag and moment curves that serve as input to performance calculations of vertical axis wind turbines.
Is NACA 0018 symmetrical?
A symmetrical NACA 0018 airfoil is often used in such applications as small-to-medium scale vertical-axis wind turbines and aerial vehicles. A review of the literature indicates a large gap in experimental studies of this airfoil at low and moderate Reynolds numbers in the previous century.
Does airfoil tools use Xfoil?
Xfoil. All the polar diagrams currently available have been produced using Xfoil, an application created by Mark Drela and Harold Youngren for the design and analysis of subsonic airfoils. There is more information and details on the limitations of the analysis on the Xfoil page.
How do I know if my NACA is airfoil?
The airfoil is described by seven digits in the following sequence:
- The number “7” indicating the series.
- One digit describing the distance of the minimum pressure area on the upper surface in tenths of the chord.
- One digit describing the distance of the minimum pressure area on the lower surface in tenths of the chord.
