5:1 Von Karman (Haack series) NC generator wanted

[FredA]

Anybody have a spread sheet that will plot out a VK NC?
I need a 5:1 4.5-inch VK NC built....and I need a drawing first.

Anybody got a tool for computing the drawing?

Just figured I'd ask before I make one.
Thanks in advance.

Use OR to model it, then print out just the NC bits?

This is the spreadsheet I've used.

Do you plan to fabricate this? If so how?

I friend said he had a friend who made bitchin NC's and could make it.
I reached out that person and they said they could but needed a drawing.
That's about all I know and I'm not sure I should disclose the person as I don't know him.

So -- sorry -- don't know the details.

I severely damaged the front of a regular FWFG with metal tip pushing it to Mach 2.4.
I need something that will do Mach 4.5 so I know the usual sources won't do.

I have an ablative formulation if you want to experiment with. Will need to modify a cheap Horror Freight spray gun to apply. Email me for the details.
