2-stage-rocket

[Scorpion_XIII]

Hello,

this is my 2-stage-rocket.
It is a SST-Rocket with GFK for booster and second stage. Booster has its own parachte that is released when the second stage starts in the air.
The second stage has a electronic that uses the earth magnetfield to detect the apogee (named MAGIER) It controls three parachtes by two servos.
The second stage has a camera
Stage separation is done with the crushing sleeve from Batkiter.

Nice launch and perfect flight

That's really nice. So "GFK" is a kind of glass fibre. What pressure can GFK hold?

[Scorpion_XIII]

Hi,

yes GFK=Glasfaserverstärkter Kunststoff=glas-fibre laminate.
I spliced bottles together with the SST method and then I laminated it with a little bit glas-fibre. So it can hold 16bar=232psi (this is the maximum of my handpump (named SKS)).

For information, 16bar=232psi is mostly the maximum pressure that is used in germany because of the SKS pump

That looks pretty sweet! 232 PSI is getting up there! Good to know crushing sleeve will work at higher pressure! Any idea how high it goes?

Cool, it looks like NASA's Terrier-Malemute 2-stage sounding rocket.

Say, I have a question: where did you find the staging mechanism? I've always wanted to have a multi-stage rocket.

[Alien Space Agency]

Actually you have to build one yourself. It consists of a rigid tube and a rubber sleeve.

Good picture, thank you.
