I don't know! $300K for a plastic airplane is a bit much for me. After all, you see what happened to the wing of the Discovery when they shot the foam at it? I've got to doubt that there will be many plastic aeroplanes around that are 50 years old. But that's what they similarly said when aluminum replaced tube and fabric. The shuttle is metal, not fiberglass. The abative tiles are sintered silica. -- Jim Pennino |

And what about the carbon fiber wing leading edge?

The Columbia was destroyed because hot gas got through the hole in the ablative tile, not because of a problem with the underlying structure. When you hit the atmosphere at 15,000 mph with a hole in you heat shield, it doesn't matter what the structure is. Is there a SR-22 that does 15,000 mph? -- Jim Pennino |

Jim
I quote from an Internet search. 1." In ablative technology, the surface of the heat shield melts and vaporizes, and in the process, it carries away heat". 2. "The orbiter tiles do not ablate during the heat of reentry". Someone started using the wrong word (ablative) and spelled it wrong and it has carried from post to post. Just setting the technical record straight.

I really see no need to discuss this with you, but my take is that if
the carbon fiber didn't matter, they wouldn't be disassembling the wing from a current ship and shooting things at it. Since you seem to be a smart-ass without humorous intentions, I just guess you're someone that knows what brought down the shuttle, and one of those folks that is always correct. WOW! I am honored to have been recognized as an inferior by you. Now, you know what you can go do.

Your statements regarding the construction of the shuttle was not relevant to the conversation about the durability of carbon fiber, as is the smart assed remark about a 15K mph SR-22. And although plastic can be repaired, we still have no way of knowing the effects of long term UV. Now go and beat your wife if she hasn't left you yet. |

Your original statement that started this sub-thread regarding the shuttle, "After all, you see what happened to the wing of the Discovery when they shot the foam at it?" has no relevance to the SR-22 since the materials used are entirely different and one is only a heat shield (the shuttle) and other structural (the SR-22). I don't know who "we" is that doesn't know the long term effects of UV on composition structures, but they are known in the industry and in the military. The C-130 for example has had composite skin pieces for about 40 years now. Further, the whole composits versus aluminium debate was beat to death right here a couple of months ago. You might try taking an anger management class to find out why you feel personal attacks are necessary when someone disagrees with you. -- Jim Pennino |

Pete;
How does one lose when stating an opinion? On Mon, 14 Jul 2003 02:44:54 GMT, Pete Zaitcev wrote: On Sun, 13 Jul 2003 21:12:26 -0500, Justin Case wrote: You know what you can do now, paisano. You're plonked. Come on, Justin, learn to lose gracefully. You were beaten on all the issues: - relevance of a hole in the RCC panel #8 to the SR-22 construction - durability of composite aircraft structures, and industry experience with such. -- Pete |
