The oil cooler will never work there Brian :)


Damn! It was a perfect fit!

I got a 16" section oof 4" square extrusion for the intake manifold, I might cut the outside top corner off and weld a new section on to make cowl clearance a
bit better. I can do all the welding I want at work for free (within reason).

The air plenum I'm thinking of resides on the right side of the redrive and from there it would be no problem having a scoop protruding down into the scoop
under the spinner. The goal is to get some pressure recovery. For a circular inlet, what would the optimum diameter be to feed a N/A 13 BREW?

Just stopped by Hayes Rotary, let Dennis know I'd step in if chairs started flying during the rotary presentation on Sunday the 11th at Arlington. You know
what contentious hot-heads those rotary folks can be. He still  cannot figure out how the center bearing in the Curtis Wright wankel comes out. The E-shaft is
stuck in the center bearing, and there is some sort of three piece arrangement that I think is a press fit around the bearing holder. Strange. I'll go over
Monday with my camera and a magnifying glass.

Thanks,
Brian Trubee

Good question on the size of the hole that would be optimum. My guess would
be around three inches. I am sure it depends on the top speed of the airplane.
At low speed and WOT there could be a pressure drop across the opening.
At high speed if the hole is too big there will be air spillage causing
a small increase in drag.

Hey I would like to see that CW engine. Perhaps I will go up a day early and 
stop by Hayes Rotary Engineering on Friday. In the mean time can you get
some good pictures of the center bearing assembly.
