"Do notice you stil need to acclerate up, which means maximizing deltaV might not the only variable to take into account. "

• Yes true, I am still doing the Math to reach to best point of equilibrium point, until now I was kinda limiting my self to a  min. TWR of 0.15 but tried to put away that limitation and check what is possible to get.
• I am still convict that is possible to reach the speed of light with these engines, I have the mental image of what is needed just need to model the idea.

"Do notice that the reactor also needs fuel (which is not taken into account by Kerbal engener), but this should be less then 1% of total. Justtake that into account"

• I will check this thanks!

Good, also, don't you forget to add use the magnetic scoop to double your deltaV  (for the high speed trip) which should be activated only when you want to slow down. This effecyively allow you to speed up to maximum lightspeed. It can also be used a a backup, if you wanted to return home ...

@FreeThinker, The reactor fuel usage, I am using the "Tri Aplha Colling Beam Fusion" no fuel usage observed at least.

Well make sure it has enough fuel to last the trip. Note: it cannot run on hydrogen, but it does on Deuterium and other fusion fuels

1. "magnetic scoop to double your deltaV  (for the high speed trip)"

• Thanks for the remind I need to redesign the ship a bit to put again the magnetic scoop

 

1. "Well make sure it has enough fuel to last the trip. NOte it cannot run on hydrogen, but it does on DEuterium and any other fusion fuel"

• Normally there is a rate of "part description" of what is spend but I don't have any numeric value to calculate this, please note that probably 17 years is ok with the fuel already inside the scaled reactor...

 

1. Trying Radial Spherical Tanks... but something is wrong to maintain the basic stability, even with empty tanks.

Found an elegant solution to "magnetic scoop", I think:

Hello back,

D:\SteamLibrary\steamapps\common\Kerbal Space Program\GameData>findstr /S /I "SY-P3X2" *.cfg
SpaceY-Lifters\Parts\CargoBays\SYbay3m2m.cfg:title = SY-P3X2 3.75m to 2.5m Conical Payload Bay

 

Belongs to SpaceY-Lifters, here opened:

Cheers!

Hello again,

After solving literally 96 problems, until now...

Hit now the problem that you were talking about (@FreeThinker), lack of deuterium, now I know that I am consuming about 26k per 4h this is almost insane...

I am trying to understand how can I create/produce by other fuel like depleted fuel or something... and at the same time trying to understand what are the best tanks for deuterium.

maybe these 4 tanks will be the necessary with a total 6,912,000 lqdDeuterium, need to recalc / test again...

Edited August 22, 2019 by pmborg

[pmborg]

Ok confirmed that is more than enough for all trip, uff... so solved all problems until now

InterStellarShuttle-v5.1 Finally Ready! (We can call this InterStellar Stage-1)

Going for a full test:

All documentated in videos so far... at this point... seams that I am going almost at infinite fuel consumption

Why the NERVAs, those are quite primitive nuclear engines (gen 1)

Those will be used just by the lander module to do the de-orbit, passing from orbit of the target planet to sub re-entry orbit, are old but do the job of re-entry.

The requisites are light and spend light fuel and at the same time powerful enough, what do you recommend?

I would recommend the "Timberwind" Rotating Fluidized Bed Reactor Engine, which has best thrust to weight.

Notice if want to preserve on fuel, the Nuclear Lightbulp is your strongest ally . It provide moderatly high isp which can be be downscaled to generate more thrust.

For the main nuclear reactor I am using a beast 16m TriAlfa which generated around 4GW, I have the fuel problem of the reactor solved, delicated tanks for him, and for 216years... of usage.

Sorry, Nuclear Lightbulb is an engine, not a reactor, lol. It is a closed cycle nuclear eninge.

Edited August 23, 2019 by FreeThinker

[pmborg]

Basically the reactor TriAlfa is using Deuterium and I can transport very easially LqdDeuterium which is being converted automatically to Deuterium.

[pmborg]

lol only now, discovered that I can run with engines at accelerated time rate: x10000!

Edited August 23, 2019 by pmborg

[pmborg]

In a matter of minutes got speed: 100,000km/s , I accelerated to much I think

At the breaking point now:

1. I knew about the Time Warp and about the time Physics Warp but not about the Hyper Warp, but I found a problem with Hyper Warp, the life support systems don't work, which means that the water, the oxygen and food that should be recycled with the systems that I had on board were not working.
2. Another thing, that I would like to have your help if possible, is about trying to get those Hydrogen Atoms from InterStellar Media with scoops, how can I do it? Probably I am doing something wrong about it.
3. Last topic the Magnetic Scoop was doing a break force of 1Kn... is useless !? or am I also doing something wrong?

Well the Idea is tha you open the magnetic scoop and activate the integrated Ultra Voilet laser which will ionize the free floating ions allowing you to capture them and creat more drag. EXactly whee and a what speed were you going when using thre magnetic scoop?

The speed was in the image about 100,000km/s the where is also in distance of Rendezvous (image) to Alfa Centauri

What is the heliosphere factor?, it is visible on thr magnetic scoop context menu. Also are in in the SOI of the Homeworld star or in  SOI of Alfa Centauri?
