The difference between what I mean by symmetrical and omnisymmetrical is that in symmetrical I have no local asymmetries which I did have in any one of these propeller blades by itself. . . Let me take one propeller blade by itself. I’m going to split it longitudinally and get an ‘S’ curve, of which no power of the curve is the same . . . changing rates. So it’s asymmetrical by itself: it’s repeated six times; positive, negative, positive, negative . . . and it comes around to dynamic symmetry. So the energy forces involved are in beautiful absolute balance. So we get energetic balance. This is asymmetry. And that’s a vector equilibrium in the middle of all this. Not only is the propeller revolving on one axis only, but we have six axes with everyting revolving in the vector equilibrium.
