A glimpse into the fascinating world of turbines that power rocket engine turbopumps

The Vulcain engine employs supersonic impulse turbines.

We see how gas is accelerated through a stator (nozzle) and deflects as it passes through the rotor, thus providing power.

The other image shows the fascinating phenomena of supersonic shockwaves induced by the stator.

On the very last day of the year - SpaceX Nostalgia

This is a test fire of an early Merlin 1A engine by SpaceX. It is ablatively cooled and launched the first 2 flights of Falcon 1 back in 2006-2007.

The 1st flight failed after 33 seconds, and the 2nd reached an altitude of 289 km but failed to reach orbit.

Getting Kickstarted

Thanks for the kick!

I never thought anyone would want to back Meco Rocket Simulator on Kickstarter. Until that fateful day, I ran a poll, and 84% of respondents selected Kickstarter+Sales to continue funding development.

Since then, I have devoted considerable time to ensuring that Meco’s Kickstarter will not disappoint - and it’s almost ready! Exciting things are happening, so stay tuned in the coming weeks!

Stay regeneratively cool - yours truly,

Dannie
