- Ideally, very small Reynolds number airfoils would be investigated using low speed a low speed wind tunnel with very accurate measuring instruments. ... The approaches are not as accurate as one might wish, but we were investigating airfoils that differ in gross ways, so we were expecting more easily discernible results than those of airfoils having minor differences. Therefore, the conclusions expressed in these reports are limited to the simple comparison of widely differing types of airfoils at low Reynolds numbers, and are not concerned with the absolute measurement of lift and drag values of those airfoils. ...

- I am planning to experiment with the bladeclac in cooperation with Profili, so I'll take blade angle from Bladecalc, and airfoils / sections from Profili, and try to produce something good.
- Yes, I can put three airfoils on the table, put all leading edges on one line, and when the trailing edge of the one in the middle touches the line that connect the first and the second, that's it.

- 4 x 106 (400,000) and some 10 X 106 (ten million) what we will say about airfoils will apply.
- Today we can calculate (with high speed computers) airfoils which maximize the length of the laminar boundary layer. ...
- As this discussion is limited to airfoils used on light planes, we will ask ourselves: What are the most significant features we would like to achieve with our airfoils?.
- With classic airfoils, those used over the last 30 to 50 years, we have accustomed to a maximum lift coefficient of 1. ... All of these airfoils are relatively insensitive to roughness (dirt or manufacturing imperfection) on the leading edge and except for the 4412 or 4415, their moment coefficient is relatively low so that the wing is not submitted to very large torsion at high speed (large Sv2/2 - see forces on an airfoil).
- In Part 1 of this series, we introduced our discussion of airfoils with a study of relative flow, Reynolds numbers, boundary layers and airfoil geometry, in Part 2, we took a look at the forces acting on an airfoil - lift, drag and moment and some of the trailing edge devices used to increase lift without too much penalty in drag, moment and/or building complication. ...
- In the last series of articles we have tried to grasp an understanding of airfoils - the sections of the wings which keep our airplanes airborne due to the lift provided by the airfoil geometry and the speed at which they move through the air.
