Uh-oh...SNAFU on the static air flow testing, we're having some laughs already. First, excitement....7 slits across (see attached photo) and initial air velocity readings (at pressure) from concave to discharge are 1) 46 mph 2) 51 mph 3) 54 mph 4) 6 mph whaaaat ?????. Anemometer malfunction LOL. re-test and re-test and nope, no error.
slit number 5 actually has a negative air flow !! (That really SUCKS) Sunnybrook meets the Venturi effect. As air flow travels down the channel unimpeded, the higher the velocity (closer to pressure source) the greater the effect. Baffling. We need baffling to break up linear air flow apparently.
Thank Goodness we didn't just slap the thing together and go to the field, hoping for the best. It would have plugged in 5 seconds and been of zero benefit. Oh well, lets see what tomorrow brings.
On a positive note, we're becoming confident we can produce AMPLE air at low rotor RPM's.
