KR> cabin cooling
Guys, I have the NACA ducts on the side of the KR and they work fine on the ground for taxi and even sitting still, but as soon as I reach flying speed almost no air comes in through them. I remember seeing someone's at the Gathering a couple years ago that had some sort of slide or something that popped out to pick up air from the slipstream. Anyone remember them or have any ideas???

Joe,
Maybe a stupid question, but are those NACA airscoops fore of the fuselage
widest point?
Mine are slightly aft, and therefore in a low pressure area, and this is
why they don't work.
My plan is to do exactly what you describe: make a flap that stretches in
the airstream when you open the NACA airscoop. But that's low on my list
of priorities, so I haven't done the design yet.

Joe I think it was Mark L who had the pic. I can not seem to find it right now, I think it was on Jim Fvone (sp) plane. Eric Pitts KR2S

I have a bunch of pictures of it. It was Jim Faughn's plane. He made a z-shaped piece of aluminum that he snaps into place when the vent is open and he wants max flow. It's an excellent idea, and I intend to do something simlilar, although mine work pretty well as they are when at flying speed. The reason I need something is to smooth the flow around the vertical member that they are up against. With nothing there, the air turns 90 degrees and heads for my thighs. With a piece of duct tape in there to create a curved inlet, it works great, so I'll build a ramp and a scoop all in one to get the flow right and scoop in more air. There's a photo of Jim's at http://www.krnet.org/mvn2005/050909158.jpg and another at http://www.krnet.org/mvn2005/050909163.jpg. There are several more past the halfway point of the 2006 Gathering stuff at http://www.krnet.org/mvn2005/ ...
