[1.7.x] Kerbal Atomics: fancy nuclear engines! (Sept 11)

Recommended Posts

Once I figured out how to properly tank up the Liberator to maximize d-v, I'm having fun with Liberator tugs opening up the Kerbol system to more frequent expeditions and transportation. Feels like a serious step forward in propulsion tech. :D Kerbals are going multi-planetary, baby!

Beautiful!

Playing through the 1.2 prerelease; it's so annoying to be limiting myself to pure stock parts. Can't wait to throw NFT into the game again.

For the 1.2-era update.

That looks...potent. Hyman G. Rickerman would be pleased. :) Are you going to go in the same direction as the stock engines as far as mounting options (i.e. switchable between inline and radial)?

I don't think so. The main direction of the stock engines is to make the footprint no larger than the largest component of the actual engine. Most of the engines in KA are already engine-bell limited, ie, they're already the "compact" model of the stock rework (and really, the trimodals are even more limited. There's not much value in trimming the attach structure down further, I might be able to get a few a teeny bit smaller, but.... i don't think it's worth the effort.

New renders for the album. I rather like how the emissives turned out. The turbopump exhausts are fully operational, they give you 15 kN of roll control, which is cool. Totally OP engine...

I really like the one on the far right. Which is that again? I usually use the center one. The emissives on the far right look especially nice.

I really need to get in to modding KSP. Any good tutorials out there? :P

Well that's cool. Can't wait to dig through the .cfg and see how you did that, although I have a guess...

I'm playing a new career on SSRSS and am at the techlevels where nukes are available. I noticed that when you run them on LH2 they are obsolete in the face of Hydrolox engines, giving only around 10% more dV for the same weight of the tank/engine combination. Anyone else notice this? Hydrolox tanks are a bit heavier and a lot smaller than the equivalent LH2 only tanks for similar dV with a nuclear engine.

I'm curious, where are the Hydrolox engine from? Forgive my ignorance, but is SSRSS a mod or something?

Since there's no real rules about what ISP engines should have, other than trying to match them to real historical engines or new engines being developed, I would suspect other mods could arbitrarily perform better (or worse) than technologies in NFT, even if realistically they shouldn't.

Also, in 1.2, KSP seems to be adding the concept of upgrading engine performance as you gain higher tech levels in engines. I'm not sure if this is unique to 1.2, Porkjet's new stock engines mod, or both, but it would also affect ISP values in mods. Some of those 'stock' LFO engines get pretty high ISPs when maxed out tech. 

Edit: okay, looked up SSRSS. Guess I hadn't seen the acronym for it yet. Is Hydrolox just liquid hydrogen / oxygen? I feel especially ignorant today.

Okay, I think my brain is back in gear. I was thinking about ISP, rather than dV. As @blowfish points out, dV is based on several factors. Nukes typically perform better outside of an atmosphere, and when the fuel weight gets pretty high.

LFO and LHO will be better in atmospheres and with rockets with less fuel. This is mostly because the engines are proportionally lighter, they tend to provide higher thrust, and the relatively lower fuel weight hasn't made the higher ISP of nukes win out.

Around 5000m/s (stock system)

That's probably a bit too low for the benefits to really show up. Might end up equalizing the lifter and orbital tank dry masses next update though, so it should get better. Figure there's already a mass penalty for needing power equipment.

I posted this in CryoEngines, it applies here too

Anyone who uses CryoEngines or KerbalAtomics - a favour please. I'm in the process of writing an analytics mode for the boiloff simulator that should solve many of the problems experienced at high timewarp. However, I need test cases. If you have a ship that encountered random boiloff at high warps in the past, I'd really like the craft file, or screenshots so I can replicate the relevant parts. 

This will be very helpful and will hopefully decrease the amount of time that the post-1.2 update will take.

An open (propellant) cycle nuclear engine.  That's an interesting concept.  Is the tradeoff higher thrust for lower specific impulse?

It's open cycle propellant AND open cycle fuel (vapourized uranium circulating in the core). The open-cycle-ness is a tech tradeoff - you get a stupidly high thrust and specific impulse with an open-cycle-fuel model, at the cost of a really nasty operating environment. I chose to represent this in the model by a simpler open-cycle turbopump model.

Ingame, this is tentatively going to mean that you can't refuel the nuclear fuel in the reactor (it'll have a very nice amount to start though). With Glowing Reputation it'll also damage reputation if run in a "sensitive environment". With NFE, you will be able to refuel the core.

Any thoughts on shielding for harsh radiation and engines like this? I realize it's probably close to implementing an entirely new mechanic into the game to deal with radiation, but there might be a clever way to simplify it. Perhaps an effect on communications? Not sure how what sort of radiation you're getting out of the reactors and what affect it would have on electronics, but that might be another way to add an effect in, for those who aren't worried about rep or Kerbal health. Then of course, methods to shield communications from the radiation could be interesting, or having to shut down engines in order to get an uplink back to Kerbal.

With the comms stuff in 1.2, could be an interesting effect.

Played with Cryo and Atomic engines quite a bit in 1.1.x. Even added the boil off module to tanks from other mods with mm patches. Really heavy modded install.

 

Never had this issue.

 

EDIT: and i checked out the old install. Got some ships with cryo tanks in flight. Didn't notice any boil off unless i cut power. Also noticed cryo tanks mod added boil off to various tanks and not me :). I did modify said patches to extend the number of cryo tanks (prevent boil off with EC).

With more messing around i have been able to replicate the boil off issue after all.

 

Using KSP 1.1.2 along with CryoEngines version:

Unwanted boil off happens on following ship:

http://imgur.com/6xbvwKD

The ship is an old RT2 Duna comms relay which pushed some other probes/sats with it when it came to Duna. The tanks are KW tanks which have been moded by me to act as Cryo tanks. Ship is in stable orbit around Duna as visible in KER window.

 

Unintentional boil off happens only when:

a) game is at max time warp;

b) ship is focused. There is no loss of fuel if i time warp while focusing another ship or in the tracking station.

 

Ship has enough battery power to survive a full Duna sun black out. Boil off doesn't seem to happen  under less then max time warp (at x10,000 or less) but happens if ship is focused and at max time warp(x100,000).

It is difficult to say with certainty whether the boil-off plugin fails during max time warp or KSP fails to calculate EC consumption and ship runs out of power. But the tank interface shows "ElectricCharge deprived!" during these (split second) periods.

 

I can provide the craft file or even the whole save game file if you want to try to collect the needed mods(i could also transfer the whole ~3.3GB gamedata folder from my install). Offhand on the ship i can see: stock, KW, CryoEngines, RT2, Coatl Aerospace, DM orbital science.

Unsure anymore as to which one of them provided the "CryoTanks" folder. Also installed are many, many other mods:

Unwanted boil off happens on following ship:

http://imgur.com/6xbvwKD

The ship is an old RT2 Duna comms relay which pushed some other probes/sats with it when it came to Duna. The tanks are KW tanks which have been moded by me to act as Cryo tanks. Ship is in stable orbit around Duna as visible in KER window.

 

Unintentional boil off happens only when:

a) game is at max time warp;

b) ship is focused. There is no loss of fuel if i time warp while focusing another ship or in the tracking station.

 

Ship has enough battery power to survive a full Duna sun black out. Boil off doesn't seem to happen  under less then max time warp (at x10,000 or less) but happens if ship is focused and at max time warp(x100,000).

It is difficult to say with certainty whether the boil-off plugin fails during max time warp or KSP fails to calculate EC consumption and ship runs out of power. But the tank interface shows "ElectricCharge deprived!" during these (split second) periods.

 

I can provide the craft file or even the whole save game file if you want to try to collect the needed mods(i could also transfer the whole ~3.3GB gamedata folder from my install). Offhand on the ship i can see: stock, KW, CryoEngines, RT2, Coatl Aerospace, DM orbital science.

 

 

Great report :). 

That fits straight with the standard "not enough Ec storage for 100000x time warp" modality of the bug. I'm quite sure that this particular anomaly is resolved in my latest builds with the analytic boiloff mode running at 1000x+. For my peace of mind, could you tell me the total power consumption of the cryo tanks and the total Ec storage of the ship?
