Was it stored in a humid environment? That sounds like the BP was damp and thus didn't burn.
So I have finally got around to properly having a look at what remains of the soyuz, and begging her rebuild!
Cutting back the damage was fairly gutting, however at the end of t have half a core stage that I know i can repair without to much challenge.
The lower section needs a little work there s a small crumple n the middle of it, the centering rings at the inter stage gap need replacing and the inner tube straightened and reinforced with coupler, the rest is fairly cosmetic. From here on up its a total rebuild.
Another part of the rebuild will be the igniter system which took a rather heavy hit in the last launch.
I have straightened out the remains of the core now, sanded back the damage, stiffened up the crumple with super glue and repaired the minor cosmetic cracks. The inner tube was then straightened with a piece of coupler and a new centering ring and extension tube glued in place ready for the upper part to be rebuilt.
The soyuz is now fully rebuilt with the final part of the repairs being being rebuilding the upper bart basically as before, however this time I 3D printed the upper transitions rather than using card stock as well as the interstage structures. Just waiting for an opportunity to launch again.
I personally built and successfully used said spider ignition system for a scratch built cluster rocket. I was really impressed with the design and results...since I am typing this as I read your thread I wish you all the success in your launch attempt!
I guess the D12-0 was in the core booster then staging to the B6-n. Got it
Would you be able to let me know what colors you used for the green and orange on your Soyuz? Several months ago I purchased the Apogee kit and am going to start construction real soon. I have a nice color for the orange found on the shuttle ET, etc., but the Soyuz color seems a little more orangeish. I also really like your grey/green. Very well done.
No problem, the grey was rust-oleum navy grey 2186, and the orange is rust-oleum painters touch real orange. I tested a few colours and these gave the best match I could find.
Thank you Wrad. I'm having a hard time finding these Rustoleum colors here in the States. I'll certainly keep trying. Thank you again.
Finally had a perfect launch day for the rebuilt soyuz, with no wind and perfect clear skies.
Again the launch was a fantastic spectacle with the spider igniting all 5 of the first stage motors very successfully . The rocket rose of the pad perfectly straight with a very scale appropriate slow climb. Staging occurred with a loud pop with all 4 boosters dropping away and the sustainer in the center lighting perfectly. The air speed however suffered with rebuild coming in a bit heavier than before, resulting in the second stage arching over at staging, similarly to the second flight. The ejection charge fired this time however with enough time to save the rocket from lawn darting. Somehow there was no zippering however the bottom of the rocket hit the ground a little fast resulting in a small crumple that will be easily fixed.
The rocket will be repaired again however with the increasing weight with each repair i may retire it as a display piece rather than risk total destruction. Gives me a good reason to think about the next project anyway, maybe a 1/25 scale soyuz if i can stretch the budget that far?
Finally some great pictures to follow courtesy of a number of people at the midland rocketry club hear in the UK.
Looking forward to seeing the pictures Wrad. Nice to retire that beautiful Soyuz before total destruction. For your next attempt, I vote for a 1/25 Soyuz or a Proton. I'd like to see you ignite all 6 fuel tanks at launch, dropping the booster and lighting the second stage.
I've just purchased my first lathe and am working on 7425 Delta II (ICEsat-2). Almost finished. I also have a question about CG vs. CP that you will probably be able to help with. Take a look and let me know what you think. Cheers.
Thanks, i do like the idea of a proton as well, I recon you can make one fly without any extra clear fins although that might be a little marginal. The delta II is a great looking rocket, I shall take a look.
Got around to having a proper look at the damage, no to bad rely. Should be an easy fix.
The good thing is that the repairs look like they will be in places that are not normally visible.
How does the motor mount look? Will that make repairs more difficult?
Its bent just above the crease in the outer tube, where the motor hook is attached, however the damage hasn't spread up further as there are lots of centering ring that kept it strong. The repair will be easy, I will just cut everything of just above the damage and then rebuild back down with couplers.
