The KSP Interstellar Proxima Centauri Challenge


Recommended Posts

later on I can share more details, (remote now)

  • If you look to the current size of the ship it is already huge, 45m diameter 1.4km long, 1 million tones when full loaded.
  • Now image a super large ring with instances of this ship and even one stage of Daedalus engines in the middle, KSP is not prepared for things of this scale/magnitude, so is very painful to do edition, some times I prefer the notepad++ to do small changes.
  • But I don't consider it impossible.

Damn, 78 years  is too long! For mission success it is critical to take no longer than 50 years, which will ensure that a 20 years old cadet still lives (at 70 years old) when arriving. Electronics lifespane also becomes problematic after 50 years of operation. We have to push harder!

The Logical steps would be 40 and 60, not 45

If you look close: "0.613, 0.95, 1.13, 1.875, 2.5, 3.75, 5.0, 7.5, 10, 15, 20, 30, 45 "

All this values are +-50% bigger except the last one, with 45 still follow the rule of 50% bigger.

But hey... I like big things specially engines!

No, the pattern is 1.25,  2.5, 5, 10, 20, 40 and 1.875, 3.75, 7.5, 15, 30, 60 mixed together

40 (which is the official release value that you have) work well and also 45 tested.

I am curious about an engine of 60, but scared about fuel consumption, but once this engine scale so nice I can only expect the best!

After some experiences here is the result, direct support to from 45m to 60m:

  • Go from 141Mdelta-V (45m) to 147.9Mdelta-V(60m)on Alfa1_8StellarShuttle-v5-9F with an extra fuel tank from x4 to x5 increase to 151.9Mdelta-V(60m).

 

  • About the one that I am trying to build is about this structure (or a huge quad cone/ring that I don't have), basically is 4 x Alfa1_8StellarShuttle-v5-9F aiming to have 290Mdelta-V

Without multiple sets/instances of this one: Alfa1.8StellarShuttle-v5-9F3 161.6Mdelta-V(60m) = 0.536c

Nw4mR3r.png

So for previous model Alfa1.8StellarShuttle-v5-9 = 0.416c Max. Speed

  • With 141M total deltaV, I have done 125,000km/s for cruise.   (Estimate: 78 years based on previous flights data to TRAPPIST1 - 18 years for Alpha Centauri (flight done))

 

For this one Alfa1.8StellarShuttle-v5-9F3 161.6Mdelta-V(60m) = 0.536c Max. Speed

  • With 161M I estimate doing: 145,000km/s for cruise.   (Estimate: 70 years based on previous flights data to TRAPPIST1 - 16.2 years for Alpha Centauri)

 

@FreeThinker 3 posts almost in a shot to resume the stuff done today, I hope not too much information in a raw...

NOTE: Earth years.

It's not exactly a lamp light... Just another fanci one that only do 50MdeltaV, but a lot cheaper!

Going to the new one at mega size:

Max Speed: Between 0.76c and 0.78c (non-reusable ship)

Dont explode in launchpad is a begging...

Hello @FreeThinker

Using already KSPI 1.25.2.5, I am trying to tuning this new version, Alfa2StellarShuttleA:

0vn97sh.png

  •  One of the problem is that I need to resize also the nuclear reactor to fuel this new engine size, and most certain the respective reactor fuel.
  • The other problem is that the is ship right now is like a block don't do any maneuver except go in front line!
  • I don't know if there is any problem with engine gimbal or if really need to push engine a little bit to bottom of the ship, I am studding the possibilities that don't cost to much weight, any idea?

Hello @FreeThinker I think that I found a bug, I will share here the image that talk more than a thousand words:

axoZgAM.png

In resume it seams that Tri-Alfa nuclear reactor is generation and consuming all energy at the same time.

I posted here because this is the new version of the SpaceShip Lander, and I was testing it...

If you look closely it consumes 482 KW to produce 1590 KW

Hello, yes KSPI is displaying it correctly but is strange that AmpYear give those numbers, 1601 for EC consumer and production.

When I replaced the tri-alpha for another conventional reactor all become normal again, with no electricity starvation.

[1] With that problem solved @FreeThinker and with this problem solved on this thread, finally I solved all last problems.

[2] At 20 of december I have done a donation by paypal, bigger than the cost of KSP itself :)because I think that your work should be recognized, I hope you have it already.

[3] By the way how did you get ocean waves on your intro video of this thread?

 

Thanks!

Hey @FreeThinker I hope you and all have been a good Christmas evening, but nothing better than pass here at the end of the day to test... the latest version guess what... :)

This "latest "version is not perfect yet... but is much better in 1.8.1 :)

These spacecraft you're launching are insanely humongous. I commend you, @pmborg , for doing what I probably will never have the patience or willpower to do.

Hello @LittleBitMore, I believe that you are referring to Alfa1_8StellarShuttle-v5-9, yes and I have even bigger ones, that work in stages but what I like on this one is that is 100% reusable and potentially can do 47% speed of light as max speed, but in practice do 41.6% in order to have power and fuel to break from that speed to arrive at the target star.

This is what is needed to travel between stars.

I think you are right "insanely humongous"! :)

1.405km long and 180m wide! :)

It can be seen from space...
