Saw a funny picture without an explanation in NK forum. Rumor mongering at its finest!

It is torn at check of the maximum superfluous inner pressure and then crumpled to place on a platform.



I have it on good authority via a source that this was a successful static pressure test article of the Taurus II fuel tank. It burst just above the predicted pressure.

The photo was clearly taken without permission.

Thanks for that clarification Chris. Athough I have to wonder if that is the correct structural effect of over pressurization. It almost looks like it crumped inwards from low internal pressure. Strange effect, but I'll take your sources word on the cause.
To me it also looks IMploded. But perhaps it was under some vertikal load and folded like a crushed softdrink can after EXploding.

That's why there's testing.

I apologize for the low-qual pics, but here's the first Taurus II Stage 1 core leaving the Yuzhmash plant in Dniepropetrovsk headed for Wallops via the Port of Wilmington.

Since Taurus uses the same diameter tankage as Zenit, I am surprised that the first stage looks so long, almost as if its the same length as the Zenit first stage, despite having less than half the first stage thrust. Does anyone here have the first stage length specs?

Mr. Kyle's excellent reference site estimates it as 28.3m.
If I like something on NSF, it's probably because I know it to be accurate.  Every once in a while, it's just something I agree with.  Facts generally receive the former.

About 4 meters shorter than a Zenit 3 first stage, guesstimating.

The Zenit first stage is vastly overthrusted for it's propellent capacity/upper stage size due to its prior role as booster for Energiya.

Despite my nickname, I'm enthusiastically looking forward to see maiden Taurus-II launch as well. It will be IIRC the first time in several decades for NK-33. Formally, they never flew, because N-1 used earlier version, NK-15.

Anyway. Their specs are fantastic. If they succeed on Taurus-II, Aerojet may have many more customers for them, and may try to build them in US.

Thanks for that.  I've updated accordingly.

If you want a better camera for arrival, let me know as I have a Nikon d3000 and an operator to go along with it......

The Zenit's engine is almost twice the thrust it needs, due to it's origin as the booster for Energia.  I'd call Taurus II more optimized for the engine capability.

As in densified Lox?Kero? As in the Lox will be below the boiling point and the Kero will be slower than molases in the Siberian winter?

It does explain why Antonio comented that the partners where so superstisous about what color it was painted a while back.

Didn't the NK-33 use subcooled LOX back in the day anyway?
