Has anybody used or know about these VG's for a propeller?

I refuse to put something that ugly on my beautiful polished carbon fiber prince prop.

It might work though. Do a search on laminar separation bubbles. That's what they are looking at. Some sailplane guys put that kind of thing on their wings. I would think that it's better to put the tape just prior to the pont of max thickness so you get some laminar flow on the leading edge.

Cheers,
Scott

Scott,

How is your testing going?

It's going well. My main problem is high oil temps. I opened up the cooling exit and added a fixed cowl flap and the CHTs are good now. One of my exhaust pipes runs close to the oil sump which may be heating the oil. The engine also only has 6 or 7 hours on it at flight power so the oil temp may come down with some more time on the engine. My pitch forces seem to be a lot better than the original with my wider chord elevator.

I'm getting 130 KIAS at about 110-120 HP without wheel pants.

Scott,

More brake in time could help bring the oil temp. down. Although, as you go to higher power settings you will make more heat, as I know you know.

A couple of years ago I was talking to a Stewart Warner rep about a more efficient oil cooler / heat exchanger, of a similar size as the one I have, in order to make a switch easier. He asked me if mine was a single or dual pass. Of course I didn't know. After checking it out, it is a single pass, of course. They do make a dual pass that is very close to the same physical size and much better at cooling. Something you might consider if you haven't all ready.

I am near Phoenix, AZ and oil cooling is a problem in the summer. I think I recall that you are in CA, if so then that isn't as bad.

I think we are all interested to hear what your max speed / cruise speeds are! (SUPER KIS)

Yes, Galin, I have been using them for about a year. I can not give concrete proof as the engine was being broken in when I first installed them. At the time I thought I got and additional 50 rpm but would not even try to defend that number. It is too easy to adjust the throttle, altitude, temperature, etc to say exactly what the increase was.

Scott, the VG is a strip of plastic that is cut in a zig-zag pattern about 6-8 long on each blade installed just outside of the spinner. It is not noticable on my Prince prop. Kent

Scott, I cut a piece of alumium sheet and used radiator hose clamps to mount it so it would shield the oil pan from the exhaust. Seems to work. Kent

Hi Tim,

I really want to get the airplane to the point where I can fly it anywhere at anytime and not have temperature problems and I have a ways to go to get there. I've been looking at the dual pass oil coolers. I'll probably have to get one. I'm interested to see how fast this thing is too!

Cheers,
Scott

Sorry, maybe you need more inlet air. I seem to recall large louvers in the lower side of the cowl of the Super Cruiser to let more engine compartment air out. Kent
