Ordered some parts. Still has a long way to go, and definitely some time in the machine shop, but it’s one step closer.

3 inch liquid might be a bad idea but what if it’s not?

@83dollaroring @purdue_seds What does “hostile takeover” entail?

Design very much WIP but

[Peter Tselekis @ps_tsele]

In the process of getting the outer airframe done Solidworks crashed at least 7 times.

:(

Shall we begin?

I think I’m going to go straight for the liquid rocket. Because I want to, but also for other reasons.

It’s becoming very clear to me that a flying liquid is a much more valuable investment than another solid rocket, and the logical progression from the torch igniter.

Now out of propellants and with the summer at its end, time to head back to school and work on my academics, and of course, the next thing I have planned.

[Peter Tselekis @ps_tsele]

21 successful hot fires later, my torch igniter project is complete. See the compilation below. To say I learned a lot from this project would be an understatement.

For the later tests, I measured the chamber pressure, with a maximum measured value of 5.03 bar.

Phase 1: Complete

Videos soon.

I have a plan. It may not be the best plan, but I have a plan.

Torch igniter, hot fire it before the summer ends.

Then launch a high-performance 2-stage rocket.

Then design a small-ish liquid rocket.

Then build, test, and launch said liquid rocket.

@hunterlanier Building missile silos out here or?

[Peter Tselekis @ps_tsele]

@hunterlanier Eggfinder? I learned how to solder using those!

[Peter Tselekis @ps_tsele]

@shawnblue Very powerful! Looking forward to the flight!

We are now one step closer reopening Michigan’s access to space.

This weekend I completed my first static fire on BlueCat, a nitrous/alcohol pressure fed liquid engine.
Thank you to Michigan Team-1 Rocketry for supporting the test.
Very happy with how the first test went.

HOT FIRE SUCCESS!
