[TMT] Never honored policy

I suspect the temperature limit is for the protection of the nonmetallic structure of the rocket airframe, rather than the strength of a metal motor casing itself...

The temperature threshold rule preceeded reloadable motors. It was to keep kiddies from burning their little hands :)

Who said it had anything to do with reloads? (besides you)

I guess I did. I was looking at the max temperature requirement as a function of having an effect on an aluminum motor case.

I'll just shut up now. ;-)

I would suspect the reason is that paper burns at 451 deg. F. 200 deg. C is

392 deg. F, this would give a saftey margin of 59 deg. F before the engine would be hot enough to light paper on fire.

Jerry, I have no knowledge of the incident in question. My reply was to David's claim that TRA has no rules in place for being reimbursed for damaged test hardware and was thus at fault in the event of a non-payment. I should have made that more clear, and for that I apologize.

You may be right, and if so I apologize for the confusion. Perhaps the incident in question (if it did occur) was the basis for adding this rule, if in fact it was not already in place at that time.

Who are you quoting, Iz??

to insure compliance with NFPA 1125, as arbitrary as that may be

NFPA 1125 - Code for the Manufacture of Model Rocket and High Power Rocket Motors, 2001 Ed. (excerpted for editorial review)

--

7.4.1 A solid propellant rocket motor shall be designed and constructed so that the temperature of the external surface of the rocket motor casing and fittings, if any, shall not exceed 200°C (392°F) during or after operation.

8.1.7 Before granting such certification, samples of a motor or reloadable motor system shall be examined as follows:

(3) Thermal testing to ensure that the casing temperature during and after static firing complies with 7.4.1

this should be in the FAQ

;)

And Ray, that's exactly what I said in my statement -- that they may have added more rules in place as a RESULT of what happened, but if the rules weren't in place AT THAT TIME, Jerry isn't liable.

good observation, Zak. I didn't know that, but now it makes perfect sense

I don't know what happened back then (exactly when is 'then' any way?), but if it's the word of Charles E Rogers, documented liar (especially when it comes to motor certification), then I wouldn't trust it to be any more accurate than a broken clock.

In 1991 TRA was not yet testing motors in house.

And from personal expeience I can guarantee you that anything printed in the TR is extremely biased towards what Kelly & Rogers want you to think, and often bears very little similarity to the truth.

Although I'm still surprised about little tidbits that accidentally slip through, like the racist comment one BOD member used about me, and another BOD member who let slip that TRA was in hot water with the IRS for failure to file required paperwork regardng their 501C3 status, subjecting them to thousands in fines.

Look, Jerry's reputation is not the best in this hobby. But TRA has a WORSE reputation so Jerrys complaints look good. Which is really sad for TRA.

That also makes no sense as I offered to reimburse all costs PLUS IF there was damage and it was refused. EVEN IN CASH, Tripoli's favorite method of payment to ease skimming.

Chuck Rogers was a BOD member and TRA prez at the time, and is still on the board. I can't ercall how far back current Prez Dick Embry goes, but he was certainly around when shady BOD deals were still flying. And of course ex-BOD ex-prez Kelly still has his fingers in much of what goes on.

How does Jerry admit to not having a waiver that he has and to not having violated a waiver that Rogers violated?

He might as well say he no longer beats his mother...

If it were any one else making the claim, I'd say Jarry didn't pay. Excet in this case, I'd say they didn't accept it. Just like they refused to accept my renewal, something they are not allowed to do.

You, sir, get it. Don't forget it was Rogers himself asking the questions and being the co-judge. It helps to keep things in context. :)
