Does the active ablation module work though? I'm not sure what that bug is but if it is working then it isn't too bad I think. If it isn't working use this instead: https://www.dropbox.com/s/4a52598x5v1jcu7/ActiveAblation.zip?dl=0 it is just the same file but it is cleaner so it should work.

Really? That is strange as the J92 is a 2.5 meter engine. Not a Mk2 engine. There is a Mk2 scramjet but I am not talking about that one.

@K.YeonI found a bug. The J-92 Scramjet cannot gimble side to side. It can only provide pitch and no yaw. In addition it rotates around its middle when you try and use it for roll control when there is only one engine

Oh man I can't wait for this mod!

Huzzah! Full sized Nexus! Is there a download somewhere about?

Any chance you can give us a real scale Nexus? Just full size using human feet. It would be amazing for any sort of real scale system play through

Hey there Esquire I'm back playing KSP so if you need any help feel free to let me know!

Sadly the miner will only mine until its local LH2 storage is full and as everything fills equally a local LH2 storage would be filled long before any sort of Massive storage tank. The work around that I used was to have just a mining installation for gathering ore and then placed the ISRU on the main storage tank. That works quite well. Assuming of course nothing has changed since I last played KSP a few months ago.

I am having an issue where after I add scatter support to Cyran all of the planets with atmospheres lose their clouds and Iltan has black clouds. So testing it out even with out scatter support installed I don't get clouds on any other planet and this is the same with and without the changes to the scatter cfg file.

The thing with Vasmir is that it is quite low thrust indeed but highly efficient which would give a terrible thrust to weight ratio to the upper stage.

One thing I would say is I don't think this type of engine would actually need any EC to run and as for cooling it might not need radiators but I don't have any real issue with either of those.

Yeah the nuclear salt water rocket is really neat as it is a continuous detecting nuclear explosion. As for the core heat module that is a component of the near future reactor system. I have no knowledge of that system but it requires a reactor to heat up and as it warms up it produces more EC per second and if it gets too hot it will over heat and damage itself. But for engines I don't know anything about nor can I help you where CFG files are concerned with that system.

I would say that you probably should not go with an externally powered engine. That will add a good amount to the expense and as this is a booster the whole thing is expendable and it is just there to launch a payload to a location. As such it would be best to keep cost down as much as possible for the booster. Considering that I would say you probably shouldn't use an externally powered engine. As for what should go there radiators would definitely be a great thing to have along with some solar panels. So half of the petals could be radiators and the other half could solar panels.

He has it in ResourcesGeneric. Here is a link to the thread and download:

Oh those are custom defined here's the CFG:

That removes the propellant liquid fuel and adds in the realistic fuels if the CommunityResourcePack is installed

Yep here is the CFG file for the NEXUS mod that adds realistic open cycle gas core nuclear rokets

I personally would say it would probably be best if this style of launcher used a self contained engine for the upper stage. As that is both lower tech and feels much more realistic for a launch vehicle and not an entire space ship. As such I would recommend some type of fission rocket probably an open cycle gas core rocket as that type of rocket has been proposed for use for quite a few heavy launch vehicles including the NEXUS which would have 1 or 2 open cycle gas core nuclear rockets for an upper stage so including built in radiators would probably work best for the nuclear rocket. As a side note I am mainly for the nuclear fission rocket for an upper stage as this is a launch vehicle and as such this whole stage is effectively expendable after boosting it's payload towards it target. As such it doesn't really make sense to have the complexity of a whole high performance power plant to power a fusion rocket as it would be a massive waste to just ditch all of that high performance hardware after you finish boosting.

Hmm that is true. Still I for one am a big fan of having excess thrust as it makes big burns much faster and more accurate. But other than that as for the model in all honesty it seems a bit more fitting to an open gas core than a closed cycle as most closed cycle designs I am aware of use elongated cylinder to increase the surface area of the 'lightbulb' allowing better cooling and more area to transfer heat to the propellent.

Ok that sounds good but still for an upper stage I would imagine that an open cycle gas core nuclear rocket would work better as it would have higher thrust and be self contained. Not to mention it is a lot closer to real world possibility than the vista. Also the 3D model is much more in line with an open cycle gas core rocket than a vista but that is always subject to change.

Ok so the interstellar mod has a VISTA in it with an ISP of 15,500 and a thrust of 2,400,000 n. Now that has a few issues such as the full size one in real life only has 240,000 n of thrust so the VISTA in that mod has 10 times as much thrust and only 33 tons so that's an issue. Now the open cycle gas core nuclear rocket would be much better suited if you keep it true to life for the heavy booster role as it'll work perfectly in atmosphere while the vista wouldn't work at all due to air interfering with the launch of the pellets. From the nexus mod there is a 6,000,000 pound thrust open cycle gas core rocket which would be more desirable. It is 6.25 meter diameter with a thrust of 3,394,000 newtons and a ISP of 1,964 based off a real life proposal for a booster. It uses uranium tetrafluoride and tungsten along with liquid hydrogen with a ratio of 5 hydrogen to 0.0003 Uranium tetrafluoride to 0.00018 tungsten. The tungsten is added to the hydrogen to increase the amount of thermal radiation that is captured and transferred to the hydrogen from the nuclear reaction.

Vista is very definitely a fusion engine here are the stats for the Vista http://www.projectrho.com/public_html/rocket/enginelist.php#id--Pulse--Inertial_Confinement--Magneto_Inertial_Fusion That is a great webpage for all of your rocket engine and realistic space ship needs. For the Vista specifically: http://www.projectrho.com/public_html/rocket/realdesignsfusion.php#vista It is worth noting that the VISTA is a whole spacecraft and not an engine. The spacecraft VISTA has 200,000 m/s of delta v. A wet mass of 6,000,000 kg a dry mass of 1,835,000 kg. So I am not sure how scalable this will be to an engine as the VISTA is a whole spacecraft including an engine. Also something that might be intresting is an open cycle gas core nuclear rocket. This is similar to a closed cycle nuclear rocket but there is no container around the nuclear gas so it does slowly leak out the exhaust but it has much better performance. This type of engine has been proposed as an upper stage engine the the NEXUS launcher that is 60 ish meters in diameter and could boost 2,000 tons to low earth orbit. Here is the link to the part about open cycle gas core nuclear rockets: http://www.projectrho.com/public_html/rocket/enginelist.php#id--Nuclear_Thermal--Gas_Core--Open_Cycle In short it has an ISP between 3,600 to 10,000 and a thrust value between 108,000 to 5,000,000 newtons of thrust. These are for real proposed open cycle gas core rockets so take them as guidelines.

That is looking nice but that isn't a closed cycle nuclear engine. Closed cycle nuclear engines have a gas of uranium. Usually uranium tetrafluoride that is in the gas state and undergoing nuclear fission inside of a quartz container. This gives a ISP between 2,000 and 3,000 for various designs. What you have there is an inertial confinement fusion engine that has a ISP of around 1,000,000. I don't mean to be a stickler but I like accurate naming of things

is there a download for any of this yet? I would love to mess around with the parts you seem to have made already
