Has anyone tried using electric fans for additional cooling
when on the gound and climb the similar to what cars use? Any thoughts
on effectiveness?
Hi
Greg,
I had a bad reaction
with the fan I had on the RV-3 initially. When it was off, I
had the switch set up so it would short the wires together. This
supposedly adds some braking action, to keep it from freewheeling.
Well, it didn't work that way. The fan spun quite rapidly from
the prop blast, and when I actually turned it on, the voltage surge it put
into the electrical system actually shut down the EC-2 for about a
second. I never tried to analyze whether it was a positive or negative
surge, but I have to guess it was negative. It might be OK one way
or the other, but I got that fan off immediately, just to make sure I
never experienced that surge in-flight.
Rusty (hoping the risk analysis goes away
soon)
