What did you do rocket wise today?

[Antares JS]

With my level 3 rocket done, I'm moving on to less stressful things for a while.

I know the feeling!

More glue fillets. I think buying stock in Gorilla and Titebond "wood" be a good investment..

 

[MidOH]

Sanding.

More sanding.

More sanding.

I really enjoyed building that kit. Might get to fly mine this weekend too.

Brain goes tick, tick, tick…

 

[GrouchoDuke]

Worked on an electronics design project and a rocket design. Gathered more parts & did software config for my 3D printer rebuild (to print rocket stuff).

Today I sanded the first 2 MD rockets again. There were still some rough spots and some tube showing. I put some un thinned CWF on the spots and sanded it smooth. Tomorrow I'll try again to put a final coat on. Last night I drew up plans for a rocket to replace the the one I cut up the other day. Coincidently the rocket I'm replacing was built about three years ago. It was named Omicron. Which is one of the 25 brightest stars in the sky. When I couldn't come up with a name I used that list for names.

 

[John Kemker]

Ordered an extra centering ring and a 4" av-bay bulkplate from Composite Warehouse for my AMW Fiber Max.

 

[Astronaut Cheeseball]

Warmed up yesterday started the primer/sand on the Thor 38.

 

[kuririn]

I know it's been done before, but I started on my own version of a Toblerone rocket.
End flaps were glued together to make a nose cone.
Added a strip of cardstock to make a shoulder for the nose cone.
Fins will be TTW at the corners, papered and shaped with an image of the Matterhorn.



Hmmm.....




Laters.

 

[jqavins]

To make that second one, you'd have to eat six giant Toberones. The price we pay for this hobby.

 

[Antares JS]

Worked on Twin Factor a bit. Nice relaxing build.

 

[lakeroadster]

Swing tested the Ahpla..

Swing tested the Ahpla..

Cool -- Do you also spin test just the sustainer?

Last night I was looking for inspiration of my next rocket build... I came across a somewhat odd-ball RIM-50 Typhon LR - https://en.wikipedia.org/wiki/RIM-50_Typhon

Looks a bit like a Nike Hercules. I like the idea of doing something others have not done but I think that Nike Hercules is probably cooler looking (although I do like the ramjet nose on that sustainer and those antennas are pretty cool).




Here is more detail on sustainer:



I did a quick mock-up in OR and it looks like it can be made stable (although sustainer needs a fair amount of nose weight to make it stable).

Completed bag 1 of my Lego Sat V. Only took about 30 minutes. 11 more bags to go.

How many pounds of noseweight.......

 

[BigMacDaddy]

How many pounds of noseweight.......

85g (but that is just a mocked up simplified model, not 3D printed or with all the various fin components on the sustainer).

85g (but that is just a mocked up simplified model, not 3D printed or with all the various fin components on the sustainer).

With all that forward fin area its going to take a lot.

So, about 0.187

I didn't.. it's basically a 3FNC... and sim's out at 1.2 Cal

Cool, just curious... Lately I have had models where the booster+sustainer is stable but sustainer is not and vice-versa... I wonder if it is acceptable to have less cal of stability on sustainer since it will already be moving quite fast when it releases and is on its own.

Ongoing work on an Arduino based remote engine test stand controller

Happy days. It made it to 60 today. After a couple of months of waiting I was able to put a final coat of Krylon on one of the rockets that have sat in the corner. I also got ready for tomorrows launch. I'm taking four 4" rockets. It's going to be a low altitude day tomorrow. It might get windy. The forecast is 8 to 9 mph winds. But it always seems to blow harder out on the lakebed.

 

[Astronaut Cheeseball]

Managed 3 coats of color before the winds picked up.

 

[jd2cylman]

Opened up my Estes Super Big Bertha 29mm and surveyed what I need to start assembly. Thinking I might upgrade the front and rear CR's with a layer of 3/32" plywood for giggles...

 

[lakeroadster]

Did a swing test on the Ahpla sustainer.

 

[Wally Ferrer]

Finished the King Dragon Workshop Pathfinder...

 

[Nateairman]

I decided to build the Arreaux this morning. It was a fun build and hope to fly it tomorrow.
