MH 42

Designed for allround RC-gliders (e.g. FAI class F3B)
Has been used on the sailplane Wizard.

Characteristics

• Thickness: 8.94%
• Moment coefficient of cm c/4 = -0.0235.
• Well suited for 23% chord flaps, 0° ... 10° deflection.
• Can be used at Reynolds numbers of 100'000 and above,
  for lower Reynolds numbers, a turbulator at x/c=40% of the upper surface is recommended.

Calculated (PROFIL/Eppler) and Measured (Stuttgart) Polars:

• Image (7 kBytes)

Calculated Polars (X-Foil/Drela):

• Image (6 kBytes) - free transition
• Image (6 kBytes) - fixed transition on upper surface at 50%
• Listing in PEF format
