Ejecting boosters further away

[nitevision92]

Hi all,

As the title says, are there any ways I can decouple boosters further away from the main rocket? I have a Soyuz-lookalike mainstage with additional boosters on the sides, and they are always hitting the wider bottom end after they decouple.

At about 4:50 this video shows you the sepratron in action:

It may take some trail and error but sepratrons are your friends. If you position them correctly they can throw your spend booster clear of your rocket with ease. But if you get it wrong they can cause the booster to spin and tumble, doing more harm than good.

Remember to turn the sepratrons using wasd keys

The other option (if you really need to save weight) is to spin the rocket along the roll axis so the boosters get flung out. Downside to that is that it's only really practical with upper stages (unless you are certain you can get the spin to stop), so I'd also say that your friend is the seperatron. One other thing to add: It can take some trial and error to work out where the center of mass is, but try not to unbalance the booster too much as you drop it unless your rocket has enough thrust-to-weight to accelerate away quickly once you've hit the stage button. Otherwise as Tex_NL says, you will flip your spent boosters back into your rocket as you eject them and you will not be going to space today.

Likewise, you can also use aerodynamic forces to separate boosters using fin/wing parts, but it's not generally practical.

You may not need sepratrons... you may just need to reposition your decoupler.

Thanks for all the help! Problem is now resolved after some trial and error- I found out the hard way that Sepratrons can burn the main rocket too.

I think there is the main problem. Separatrons can help but if you have wider bottom then you would need to reduce throttle and let wait for decoupled stage to clear the way. Or just redesign so here wouldn't be any need for additional separation.

And there is a more kerbal way of staging. By decoupling several seconds before burnout so the stage escapes upwards not downwards , Jeb would love that!

If the bottom end is wider, maybe multiple separatrons, positioned near the bottom of the stage (close to center of mass on the spent stage), blasting outwards to help the decoupler push the stages away. I did that before I started using Perfectrons aimed to apply braking thrust to the stages. It also helps with that annoying flip that sometimes happens separating an upper stage from a lower stage.
