I'm looking for some first hand experiences on techniques to protect the leading edge of fins from heat during a mach 3+ flight. The sim shows me hitting a max speed of around mach 3.3. The fins are 1/4" machined solid carbon fiber plate.
I've read about Jim Jarvis' method of coating them with a high temp epoxy like Hysol. I've also heard people mention placing a folded metal foil tape over the edge.
I'm most curious about the metal tape method. Is the tape affixed permanently with epoxy? At mach 3.3, isn't there a high chance of air getting under the tape and it being ripped off? Or simply being pulled off of the leading edge by drag?
If I go the hysol route, does anyone know of a distributor that sells it in quantities less than $100?
Any thoughts on this would be appreciated... Thanks
