RE: RE: Prop construction

Art,

I thought I might get into trouble mentioning faster airflow on the top of an airfoil. I also do not usually speak of airflow in term of Bernoulli effects but rather use Newtonian physics (just ask Kang and Bill about my rants).  However, for the air to curve downward (assuming an aircraft wing flying right side up), the air on the outside of the curve must move faster than that on the inside.  The air really does travel faster, relative to the wing, on the top of an airfoil producing lift than does the air on the lower side.  This is a result of Newtonian laws as one can surmise from thinking about air moving uniformly around a curve (or in high-falutin terms, the airflow must have "curl" to produce lift).

Bernoulli effects are just outcomes from Newtonian laws but the former are often misused.  Thanks for keeping me on my toes.
