Who SELLS Blades? | 17 comments (17 topical)

Clumsy me with all my words. The tlg blades need a curved radius (rounded) leading edge. The sharp leading edge and camber-only aerodynamics is a terrific idea but suffers the problem that the blades must always, always run at a fixed TSR to the wind as governed by the load. Any deviation including that from wind turbulence causes the leading edges to flutter (depending on their thickness). Flutter destroys blades over time especially those of aluminum. A rounded leading edge would be better for this reason.

The reason for the quiet operation of these tlg blades, of course, is that these blades are thin and normally have less parasitic drag. This is a strong point in their favor.
