Fiberglass Water Rocket

Post by arjan »

Today I launched my new "low pressure" fiberglass water rocket.
Launch pressure 100 psi
Volume 2.2 L
Waterfill 0.6 L

As you can see there was a lot of fog this day, almost lost the rocket because of it
My blog will be updated later this week.

Hi, this looked like a really good rocket! Giving that it is fiberglass, don't you think that is should be able to hold higher pressures?

Thanks,
Randy

Hi randy,

Yes I think this rocket will be able to hold higher pressures, this was the first flight of this rocket, it was my first cable tie launcher, and there's a inline deployment system that was not yet tested in flight. So there where a lot of new things for me to try, that's why I kept the launchpressure low.

I think the burstpressure will be somewhere around 180 psi or maybe 200 but that will probably be the max. I build this rocket out of glass/epoxy because FTC and similar tubes aren't available in my country, so decided to build my own "FTC like" tube, the wallthickness is slightly thicker than a pet bottle.
I'm going to increase launchpressure every flight and go on untill it bursts.
