How You Build A Rocket Motor(Song): / how-you-build-a-rocket-motor
Backing track: A Brand New Sunset (Modern Version) - Joe E. Lee
Lyrics:
There are several parts you need to build a rocket motor
A nozzle and a closure and an insulator
You shove them in a case and then you fill it up with sludge
Don’t eat the sludge (it looks tasty!)
The forward closure’s made of 6061-T6
It gets an O-ring then another then a 3rd in case one splits
Tap the hole for the transducers
That’s how you build a rocket motor!
Now it’s time to make a nozzle and that comes in several parts
A graphite throat, a carrier, a whole lot of heart
These parts go on a lathe and then we make a lot of dust
Don’t breathe the dust (I love my lungs!)
The pieces go together and you seal them with ketchup
Just kidding it’s not ketchup it’s room temperature vulcanizing silicone
Now the nozzle part is over
That’s how you build a rocket motor!
And now it’s time, to make the sludge
Delicious sludge, don’t eat the sludge!! (It’s not worth it!)
You take HTPB, IDP, aluminum and mix
Then add the perchlorates, yum!
Now MDI, to cure the mix
And then you vacuum degas all the bubbles til the sludge gets thick
And when you’re ready pack the tube with 40lbs of cookie dough
And then you wait a bit, just a bit sec
Finally, remove the core
And that’s how you build a rocket motor!
Can we be done?
No! Now there’s one more step that’s left before we see if this thing works
We’ve gotta build a test stand and then work out all the quirks
Now we fill the thing with water, and pressurize it hard
69 bar (nice!)
The motor passed a hydro-test so now let’s light the match
But first we’ll get it polished to ensure that it looks snatched
And don’t forget the paint good sir
Cause that’s how you build a rocket motor!
