Update (Sidewinder Nozzle Comparison)

This past weekend was busy and didn't leave a lot of time for rocketry. I did manage to get the first half of the new nozzle off the lathe and start on the second half. The first half of the nozzle is pretty hefty; I have to remind myself that this motor will produce over 1,600 lbs of thrust with a total impulse of around 8,000 lbs, so a nozzle that weighs in at 4-5 pounds isn't really an issue. In the photo it's next to an early Sidewinder missile nozzle (on the left). Compared to that nozzle it doesn't seem too hefty at all...

Looks sweet!
As a metal lathe owner and maker of many graphite nozzles, I can readily appreciate the undertaking.
Your blogposts have inspired some additional metal nozzle CAD time.

Life wouldn't be worth living without a taper bar.
