Talk:Camber (aerodynamics)

message: I added a different graph which I believe is more precise or clear. I doubt the previous one has errors in defining "upper, lower camber". It is not very clear that the dash line is acturally cordline. --Natasha2006 14:58, 3 April 2007 (UTC)

message: You stated the equation for Z(x) but neglected to define your constants a and b. Please explain these values.  —Preceding unsigned comment added by 209.255.10.54 (talk) 13:48, 20 July 2010 (UTC)
replies: text: The equation given for Z(x) is a degree 3 polynomial.  There is an unlimited number of such polynomials but by specifying a and b the result is a single equation.  An aerodynamicist who is defining a suitable shape for a reflex camber airfoil must specify the values of a and b that lead to the chosen shape.  There are numerous reflex camber lines that have been found to be suitable and each one has its own value of a and b. Dolphin (t) 22:35, 20 July 2010 (UTC)

message: what's the name please for the curvature of the middle line between upper and lower surface? can't be camber because camber is defined as the asymmetry between upper and lower half. how does one call the curvature if you take a perfectly symmetric airfoil and bend it upward like a vault (convex on the top, concave on the bottom)? I tend to think that the definition of camber in en.wiki (https://en.wikipedia.org/wiki/Camber_(aerodynamics)) is wrong and that camber is the name for this curvature (as it means simply curvature in other contexts)... thanx!

replies: text: At Airfoil#Airfoil terminology the median line is described as the camber line. The curvature of the camber line doesn’t appear to have a special name. The camber line is unlikely to be the arc of a circle so it couldn’t be accurately described by a radius of curvature. Dolphin (t) 14:14, 30 September 2023 (UTC)
