Decouplers to Orbit - KSP 1.10.1

[@Stratzenblitz75]

Big thanks to Ridge for sending me this wallet and supporting the channel! Here’s the site if you want to check them out! > ridge.com/S75 Also, please let me know what you think about this more "behind the scenes" style of video! I've been trying this more and more lately and I've been enjoying making this style of content. There is a lot that goes into these videos and I think its interesting to share the story behind how it all came together.

Two things I really enjoyed about this video: 1) The satisfaction of someone having done some math in regards to engineering, and having it work out perfectly. This stage should have a DV of 3000 m/s, and what do ya know? 3000 m/s on the dot. 2) With just about every insane mission profile in KSP involving many hundreds of parts, I quite enjoy when the first stage(s) detach and you can feel the performance of the game get better. :P

[@Stratzenblitz75]

Its only ~1000 m/s, which is much lower than what would cause heating damage. I also found it interesting that this didn't cause any heating damage. I was expecting to have more issues with this part of the mission so I'm glad it went relatively painlessly!

I liked seeing the math and thought process behind this. It's way more entertaining than just the run.

[@thesentientneuron6550]

You know, this is actually a very useful way to get things into orbit.

[@Stratzenblitz75]

Decouplers aren't more mass efficient than orbital rockets I think, but they should be better if you want to go further. Like interplanetary.

[@thesentientneuron6550]

@@Stratzenblitz75 This way, you wouldn't require massive, laggy rockets just to got your interplanetary spacecraft to orbit. Makes testing them much less time consuming too. Could you please elaborate how you did the calculations for your successful decouplers to orbit ship? How did you figure out the delta-v needed to escape the atmosphere?

[@Stratzenblitz75]

@@thesentientneuron6550 Yes! Fortunately, the math is quite simple. First, make your payload and figure out its mass (for example, lets say our payload is 2 tons). Next step, figure out how much velocity you need. For kerbin escape velocity, you need 3400 m/s, so lets you use that. Next, figure out the impulse you need. The change in momentum is just the mass times the velocity, so 3400*2000 = 6800000 N*s. Since the hydraulic detachment manifold provides 4500 N*s, you will need 6800000/4500 = 1511 decouplers. To cut this down, I've learned that you can use physics timewarp to increase the decoupler impulse. With 4x warp you could get it down to 377 decouplers. Yea that's still a lot. I think a rocket would be better suited. You can certainly make a rocket for less parts.

This. This is why I love KSP. The amount of fun you can have with a simple understanding of physics is amazing! Wonderful video!

[@tristianity8529]

Incredible, the fact you even attempted something which seems impossible and actually did it. Madman

[@lost4468yt]

2:03 that flickering on your MATH thing is caused by z-fighting. Z-fighting occurs when two polygons are being drawn on the *exact* same plane. Because of how rasterization and floating points work, depending on the camera angle, distance, etc, some parts end up being in-front while others behind, and when you change the camera etc this changes rapidly, as you can see. To fix it, just offset them ever so slightly, e.g. 0.01 will often be good enough. But do note that the offset in a game like KSP, will be dependent on the distance from the camera. If they're right in-front of you, 0.0001 might be good enough. But if they're that far away, it might need to be 0.1 or something. But it's easy to fix.

[@ticklemesenpai447]

I really love these conceptual videos with the mathematic explanations.

[@TeraV]

You can think of each decoupler as a stage with an engine outputting the force equal to the ejection force and consuming its propellant in 0.01s. Total delta-V scales with propellant in a logarithmic relationship, so even though the individual impulses keep getting smaller and smaller, it's the impulses approaching zero, which means the total delta-V always increases.
