What did you do rocket wise today?

Ah, GBI induction stabilized rocket. Looks like something GlenP could have incorporated in his Orion ascent abort test build. You are on the cutting edge, buds.

I have only one word for that: Bloodyfreakingorgeous!

My daughter and I had a great time at the CMASS Winter Follies launch this weekend. Between the two of us, we burned 15 motors in four launches. Even though two of her flights CATOed, they went down in spectacular fashion.

Warning: Awesome rocket carnage video.

Built a carry tube case for launch rods !! ZOWEE !!!!!!!

I’m loving that last one with the three canted motors - got any pics that show some more details?! [emoji16]

I am an advisor to our Rocket Team at my Tribal College. We have been invited to participate in this year's First Nations Launch Competion sponsered by The Wisconsin Space Grant Consortium & funded by NASA. The purpose? To get Native American students involved in STEM projects. So today we launched a small Estes rocket put together by my students & shot video of the launch which we will be uploading to the WSGC website. This is a requirement of the competition. We had a successful launch with a light snowfall & a light wind. Recovered the sucker too.

And this morning before going to work I did the final assembly on my Estes Expedition. Now for some body work, filler & sanding, before paint.

Congrats on the invite and successful launch. Best of luck to your team.

Peace.

Woo, you had to dig to find that one, or you have a good memory

What in tarnation is "Induction Stabilization" ?

iirc its also called Gas Dynamic Stabilization and there is at least one thread around TRF on it.

We'll tell you, but you have to be inducted first.....

You remember well! Its been awhile since the mk18 last flew, and I finally decided to start working on the mk24

Looks like he used a Fliskits Tres motor mount kit. They were available in 13mm (fit BT-50), 18 mm (fit BT-60), and 24 mm (fit BT-70). When the Tres first came out (2004) I upscaled it to 54 mm motors.
I have a bunch of build pictures since I posted a thread but the pictures aren't in the thread anymore.

Unboxed my next rocket

Added another kit to the build pile... figured my L3 build needs a smaller brother, so I picked up a LOC 3” Sandhawk kit. It fits nicely between the 5.5” L3 Sandhawk, and the 1.5” Parkflyer Sandhawk

Applied to a flight controller NASA entry level engineering job. Who knows? Haven’t heard back from my NASA hr buddy in over a month. Really this job search thingy is wearing me down. Can’t seem to land an interview anywhere.

I even have TRF people asking for my resume’ for cripes sake. LOL.

Uses the rocket exhaust and a series of cutouts in the rocket body to move air in a stream through the tube. Similar to the Venturi effect, I guess, but I'm no scientist. Good option for finless scale rockets like the Peacekeeper, Gemini Titan, etc.

Nytrunner: Not a good memory, a lot of digging. But when you said "my first post" my curiosity got the better of me.

Props for persistence, although my early musings couldn't have been worth the effort hahahaha

Couple of interior fillets on my Nike-Tomahawk.

Finished Build #3 ... a "converted" Loadstar II - I call it "I Am Canadian!"

Don't give up on NASA. With the government shutdown NASA is shut down too.

Best of luck. Next stop TARC, or is that just high schoolers?

After my graduation in May of '95 I went about six months with only a handful of interviews and no offers. Then in November I had the task of picking among four.

Hang in there, and good luck with NASA (assuming flight control is a position you really want).

Received my Level 7.0 Top Secret, burn-before-reading, eyes-only Agent's Technical Manual. Not that I'm a member of International Rescue's investigator network. Not me. Nope. Just a rumor...

The sustainer is my testbed for electronic staging. It's inspired by the Estes Magnum Payloader. It's been lengthened a little to accommodate all of the stuff for staging and recovery, and I recently wrapped it in CF because I wanted it to be more durable for all of the testing.

The booster is a canted 3 x 24 mm motor mount. The fin shape on the booster is also inspired by the Estes Magnum. I bought the motor mount from Fliskits, and it came with cutting guides for the BT50 and BT70 tubes. The only challenge was drilling holes for a launch lug through the booster and transition. (Unfortunately, I don't have a picture.) Those holes also serve as the pressure relief vents for the gap staging.

It flew on Saturday with 3 x D12-0 --> C11-7 as a way to test my altimeter for airstart staging. This is the third time I've flown the cluster booster, and each time the BP --> BP staging has worked flawlessly. Next time I'm going to fly the Magnum sustainer with true electronic staging using a different booster, though I suppose I could load up the canted booster with 3 x F44s.

Thanks for that, Joe. Adds a little more information to the pdf link in the thread. Hmmm, makes me feel like experimenting. Now, where was my scrap 7.5" tube?

Thx for the info. Guess I've got some extra reading to do.

Kool! Thx. Even more reading...

I'm going to try and make the induction tube removable on the mk24 (probably rivets) The mk18 has held up well considering it's an untreated BT-60, but it's gotten a little toasty after several flights.

These are the guidelines I use, but to keep the GBI proportions, I have to fudge a couple things

LOC Mega Magg is coming along, so far, single deploy only. Fins, MMT, and motor retension along with internal fillets all done and nose cone tracking bay completed. External fillets up next then drill for the rail buttons. When and if I start getting a paycheck again, I'll probably order the AVbay/payload section for this to fly dual deploy. Sitting next to my Mega Der Red Max for size comparison.
