Solid rocket boosters are falling inwards when ejected


Recommended Posts

I've attached a screen shot of my design. I've tried many different iterations, but they all end the same - when I eject the solid rocket boosters, they tip inwards (instead of just sliding off) and destroy all my main rockets. I've attached the struts in different places, removed them from the tops of the boosters, I've attached nose cones to the boosters, I've tried different boosters. Nothing seems to work, and this USED to work flawlessly. Yes, I am using the tall decouplers...Help!

Which way your radial stages go can depend on where the decoupler is. The decouplers fire with an amount of force that pushes the ejected stage away, and that can cause rotation.

I'll also say that Sepratrons are your friends. Use them. One each on the top of those BACCs, and maybe another one or two on each of those radial Jumbo 64 tanks.

I'll try out the Sepratrons. I keep hearing about them but I've never tried them.

Also note - I have 2 decouplers on every boosters. One at the top and one near the middle.

I guess the weird thing is that this used to work. In fact, I just loaded some old designs that used this configuration - designs that initially succeeded and got me to the Mun - and they just failed this time (boosters fell inwards and destroyed all the mains). Did I hit a weird bug in the game that's causing some sort of atmospheric effect, maybe? This has only been a problem for the past week or so.

Ironically, the small flat decouplers may serve you better.

Your discarded SRB starts in contact with its parent, and any rotation forces the other side away rather than rotating one end into the body.

Just don't have *anything* that sticks out below them.

What also works for me, on some of my massively larger designs.

If your parent vessel is rotating significantly, all discarded stuff will want to fly sideways, not straight down.

This seems to have changed for me too. Now I need to always have sepratrons and sometimes I need to stage them prior to the decouple or double up on them. I didn't use them before (.24)

I've seen this too, mainly with the hydraulic decouplers (the big flat ones). For some reason, they eject with a rotational impulse, like they apply the ejection force from the bottom, just a moment before disconnecting from the top, or something like that. Strut placement sometimes helps, but not always. I haven't seen it with the TT-70s as much, but it looks like you are. I've usually just used sepratrons to overpower it and fling them away.

I don't have a clear understanding of why this happens in some of these cases, and just haven't taken the time to experiment with it.

If you do change the decoupler type, you'll probably want the smallest ones, the TT-38K models, not the hydraulics, since in my experience the hydraulics exhibit this problem the worst.

Oh, and if you add sepratrons, be sure to angle them so the exhaust doesn't fire right into the fuel tanks. Multiple sepratrons jetting into the same tanks will sometimes detonate those tanks.

This issue is confirmed in the bug tracker so I would hazard a guess that a hotfix is in the works. At least I hope it is, game is pretty much unplayable without proper decouplers.

Here is the thread for this in support/bug http://forum.kerbalspaceprogram.com/threads/88026-Radial-Decouplers-3-75m-Decoupler-Issues-%28Return-of-the-Kraken-0-24-2%29

AH! Thank you. I will await the update, then...

Shows you how often I've played with the hotfixes doesn't it? Too busy moderating posts and threads. That's my excuse and I'm sticking to it.

Well, since there's already a bug thread about this, and an entry in the Squad bugtracker:

Have a nice day!
