Cooling Inlet Design
Today was spent working on the cooling system inlet design. After making a few plugs I wasnt happy with, I turned to AutoCad to model it on paper before building. It is so much easier when you can see exactly what you’ll end up with before you start. I really do need to start learning 3D model. It would make my life much easier.
Initially I started out with a few hot wire cut pieces.
Pat was happy with this design, but I was not. I am not comfortable with a funky NACA scoop instead of the tried and true ram air inlet. The current plan is to first make a ram air inlet, then add the ramps (so Pat is happy) and if things don’t work out, I’ll have a fall back position. Chop off the ramps and I am back to ram air!
This is a pdf file of the cowl design/cooling system design I came up with. It is as tight to the engine as I could make it (1/2″ clearences over the spark plugs and plentum box).
Tomorrow, I’ll glass the inlet tube I made, then start working on the ducts. Much to do, much to learn.
