Solid Rocket Boosters!

[NeptuneSky]

Supported Game Version: v1.5.10.2

I've been wanting to play with SRB's since we first saw them in the update roadmap. Sadly we haven't gotten to see them in vanilla yet, except a nerfed form in the career prototype, so I took it into my own hands.

There are 4 different widths, 2 wide up to 8 wide. You get to choose a custom height, rotate the nozzle, or choose whether you want the taper on the skirt via the right click menu.

This is one I am very open to suggestions for. Please do leave balancing suggestions in the replies.

Here's a few general stats:

ISP: 130
Fuel Density (as compared to liquid): 2x
Dry Mass Ratio: 15%
Thrust Formula: 75t * ( height / 2 )

How to Use:

1. Close the game, open Steam, then go to your library.
2. Right click SFS, then go to Manage > Browse Local Game Files.
3. Navigate to Mods > Custom Assets > Parts.
4. Drag and drop the asset file from the below Google Drive link into the Parts folder.

Google Drive - solidfuel.pack

The game will automatically load the parts when you re-open it. You'll find them under the Engines pick category.

Major update to the available sizes, I felt width should increase as height increases rather than each width being proportional to the last, and there needed to be a lot more higher height boosters. Let me know what you think.

nice a solid boosters custom parts pack Neptune Sky

now we're gonna need solid fuel blocks lol

now we're gonna need solid fuel blocks lol

ASoD said it's not doable with current Booster Module. Would be possible when using usual Engine Module, but then boosters would be able to shut down.

I’m attempting to figure it out, but things get “interesting” very quickly.

oh ok

Part pack updated for new modloader release. Just redownload the pack from the same google drive link and replace the old file at the new custom parts location.

 

[NeptuneSky]

v2.1 is now out at the same google drive link. Added a toggle that lets you turn off the taper on the skirt.

Something to get excited about in the next update. Waiting on a bug fix patch from the devs to release but it's something I'm certain people will like.

Does nozzle rotation effect thrust direction?

Does nozzle rotation effect thrust direction?

Of course! Wouldn't make much sense if it didn't lol.

What did you use to calculate the incline?

What did you use to calculate the incline?

I actually didn't need to calculate it, I added the booster module to the nozzle instead of the parent game object which automatically tilts the vector for me.

However, this is what is causing the bug that I am waiting on a fix for. I guess I could just use a custom module seeing as the inputs for the vector don't accept sin/cos calculations but it's a bug that will be fixed anyways so wouldn't be worth the effort.

I really want to start making mods, but i dont know how to do really any coding. Any tips from all fellow modders?

Hello KaneVRHL,

Please create your own thread in the Help and Support section if you have questions about modding. We would like that threads dedicated to mods stay on topic.

v2.2 is now live! Finally added angled nozzle, as a recent patch finally fixed the bug that it caused.

I got the same thing as SpaceExplorer67852. I'm using Steam and MacOS Monterey (12.6).

idk why someone would turn it off, but still nice feature.

What if we do the same thing on a liquid fuel engine getting controls through actual thrust vectoring rather than torque? How differently would the engine behave

if you wanted to stack them side by side... its a good idea.
