Simple Soyuz

630 moosefoot  5.9 years ago

Made just for my own amusement's sake.

So... Once on the launch pad, let the solar panels fold in first (I know, not the most elegant thing...) which takes a few seconds, then:

Activator 1: Start first core stage and strap-on boosters.
Activator 2: Release clamps (do it simultaneously as "1")
Activator 3: When the boosters burn out at T+40, drop them. They will veer away from the core stage and form a brief "Korolev cross" as on the real Soyuz. The core stage will continue to burn. This also jettisons the LES tower.
Activator 4: When the core stage burns out at approximately T+80, drop it and ignite the 2nd stage. This also jettisons the payload fairing.
Activator 5: When the 2nd stage has burned out at approximately T+100, drop it and release the Soyuz spacecraft. This also deploys the solar panels.

...You should now be at 250,000ft+ and the air resistance is negligible. Disable "1" to shut down the gyro and enable RCS thruster control on the Soyuz spacecraft... Now you can spin around and do whatever for a while. The best thing to do is to align the spacecraft roughly horizontally, in preparation for the next step:

Activator 6: When you begin to lose altitude faster (keep an eye on the gauge), separate the re-entry module from the habitation and service modules.
Activator 7: When you are approaching the ground/sea, deploy the landing chute and descend veeeery slowly.

So it's as easy as 1-2-3-4-5-6-7. The gyro keeps it going straight up, so it's not the most realistic thing ever, but yeah - it was just for fun.

There is moderate roll control provided right after start by the booster aerofins as on the real Soyuz, and you might want to counteract the rocket's built-in tendency to roll a bit. There's no actual gimballing or anything though.

There are several cameras: One launch pad overview camera, one directional action camera right underneath the rocket, one orbital camera on the core stage and then the usual cameras around the main spacecraft.

All in all, pretty pointless, but it was a fun and lengthy build.

OBSERVE: As with all these stock missile-based rockets, make sure you let the previously active ones drop out of the vehicle before performing any new actions. It only takes a split second for them to drop out, but if you're slightly too quick with the next action everything probably just blows up.

Also, you might want to set the physics level in-game (accessible in the settings when you're in the level) to "low" if it still insists on blowing up all the time.

    Just wondering, why does everyone make Soviet jokes even though the soviet republic fell in like 1970's or something?@asteroidbook345

    @moosefoot,Thank you,The problem is the physics. I set it to low. :(

    Okay. I'll help fold the panels if you need any help. This is still an awesome build! Good job!

    @MrTyTheGreat I made the spaceship with its solar panel mechanism first of all, just to see if I could mimic the way they fold on the real thing. Later on during that coffee-fueled building binge, when I suddenly realized that I had built myself a huge rocket to go with it, I made some half-arsed attempt to "pre-fold" them, but realized it would take ages to get it just right so I dropped that for the time being.


    As for the pad, well, it's a "simple Soyuz" and I wanted to keep the part count to a bare minimum while still keeping the essence of the Soyuz pad (rocket is held floating by four clamps, color scheme from the Kourou pad etc), I have a pretty slow computer and again, all of this was just made for myself in coffee-soaked boredom, I didn't intend to publish it at first.


    If I make an updated "scale model" (ie not "simple") version for publishing later, I will make a more realistic pad, pre-fold the solar arrays (if I can), add heaps more detail and tweak some other things here and there for realism (some proportions etc)


    @WaspWaspWasp It's a known issue with these rocket contraptions that use the stock missiles for propulsion. They're very unstable and it seems like the game version has a huge effect on whether it'll work or not, as does the physics level setting in-game, presumably because the developers are constantly tweaking the physics and behavior of game objects. Several missile-powered designs I made in 1.6 just blow up instantaneously in 1.7, for instance.

    But this particular model works fine for me at least (in v1.7.0.6, Windows, physics set to low), I test-flew it dozens of times before hitting the submit button. It only blows up if I manhandle it, which is to be expected.

    You can do some tweaking if you want.

    And,It always explodes when launching.

    This is beautiful. If you could take a day and 1. Cram the solar panels into the fairing. (Fold them up.) And 2. Make the launch pad prettier, this would be a lot better. For Bronze, this is on par with a lot of Golds, so great job, and keep up the good work! (That screenshot of the booster sep. makes me want to build another rocket. :P)
