I think you are supposed to use the water as a pressurized propellent...Originally posted by Blue_Ninja_150
OMG!
On a slightly more serious note, what PSIs would you need to loft a 5 gallon jug? A gallon weighs 8lbs, so even at half full it would be 20 pounds, and you need what, a J or K motor to safely loft that?

Yea.. I know. I have done water rockets once before, teh day before i got addicted to BP. I was just assuming what you would need for a solid propellant motor to loft the same weight, hence the psi's.

1-1.6 This code shall not apply to model or toy rockets propelled by pressurized liquid rocket motors containing less than 8.45 oz (250 ml) of water.
So if you state has adopted 1127, you're looking at all the regs behind a HPR.

I don't think I would worry about that one too much anyway. A LEUP for water?Originally posted by jcrocket
