MID 107 DB Name: MID 107 Family: Midic Max thickness: 10.0% at x = 26.50% chord Max camber: 4.0% at x = 56.02% 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. This airfoil has thickness of 10%, and camber of 4%. It is intended for all FF airplane models for low speed with Re numbers from 40,000 and more.
Airfoil must have appropriate turbulators at the top and/or bootom side to provide turbulent flow on up side from 30%c and on down side from 5%c. By some models, they fly only with higher lift, turbulator on the bottom side is not need. To make turbulators more effective at small Re numbers, on the top side invigators after 50%c are welcome.
Because of relative big thickness of 10% it is easy to build models also with wing of high aspect ratio to the conventional mode with wooden spars.
Drag coeficient CD at zero lift CL=0 is very small in comparison with usualy airfoils wit high cambers, so the model can be suitable for succesfull vertical launching.
