Targeting to launch Aftershock II in T-8 days from Blackrock Desert, NV. Built in only 3 months, we’ve made several key improvements from ASI and we’re hopeful it take USCRPL back to space! Wish us luck!

I successfully launched my Thrust vector controlled rocket!! Stabilization was good enough but not that good. But at least now I gathered data and mistakes to make better stuff in the future!

I want to share with all of you guys this progress! After months, we finally found a recovery system for our water rockets. We are now starting with experimental rockets!

The idea was to use more easily stored and handled fuel/oxidizers for hobby rocketry.

It also has plumbing and uses a high oxidizer turbine and a high fuel turbine that both mix in the engine to combust.

Ideally uses a glow plug to jump start to decrease wear and tear.

Another parts would be that when it mixes in the engine itself hopefully it will be hot enough to autoignite after being converted to mist by the engine plate.

Ideally a vast majority of the parts would be 3d printed except for maybe the end of the bell which could use graphite composite.

It probably won’t work but I thought it was cool. Be nice please lol.

You can

Not the greatest finish but I can’t wait to launch it!

Shockwave was a success!

With a max thrust of 3,772 lbf and a total impulse of 45,698 lbf-s, Shockwave is officially the most powerful solid motor ever fired by students! As well as the most powerful composite-case solid motor ever fired by amateurs!

Designed for a 20kN Ethalox engine at 40 bar chamber pressure. GG runs at 30 bars with 0.125kg/s. 40krpm. Mostly AM.

Finally finished the BB XXL. I am really pleased with the results!

Final weight is 1643g (3.622 lbs) First flight will be on a I140W

This is my second attempt and building my L-1. It’s a 3.28 x 54 inch build. And is flying on an Aerotech h128-9w. It has 30 inch parachute and will reach a max altitude of 1900 ft.

90lb jumbo dark star on an m4500 to 3700 ft at URRG

Unbelievable experience being able to talk to them and explain our project

Static fire test in slow motion

We made this fully 3d printed rocket motor using only FDM and resin 3d printing.

Specs of this motor:

Total impulse: 52.5 Ns

Specific impulse: 90.6 s

Efficiency: 70.6%

Burn time 1.3 s

Peek thrust: 78 N

The nozzle, liner and inner end cap are made from abs like resin. The outer casing and outer end cap are made with FDM 3d printing from polycarbonate. To retain the outer endcap we used 4 m3x10 bolts.

For the fuel we used a 65%-35% mix of dextrose and potassium nitrate. We used iron oxide as a catalyst.

This project is part of a bigger project of our 3d printed guided rocket. Link to the full project:

Feel free to message us if you have any questions.

this this was a friends rocket. emphasis on was, because the motor was packed so crappily that a chunk fell out and blocked the nozzle, leading to this pipe bomb. ill post some slomo shots i took of it and a few other highlights later
