DB Name: MH 33
Family: Hepperle
Max thickness: 7.3% at x = 30.06% chord
Max camber: 1.0% at x = 41.74% chord
Available data sources:
JavaFoil+Calcfoil stall+Eppler ext transition
XFOIL ncrit=9
Notes:
Coordinates from TraCFoil.
Commercial use of the airfoil may be restricted by the designer's copyright.
Thickness: 7.28%
Moment coefficient of cm c/4 = -0.03.
Well suited for 20% chord flaps (but not absolutely necessary).
Can be used at Re of 100kand above.
Better performace in the low Cl range than the MH 30 and MH 32, but thinner.
