Ignalion Posted July 16 Share Posted July 16 (edited) I don't know how much support for the mod is there, but maybe someone can help me figure this out. Some crafts give me a very bad stutter. Like every second game is freezeing for another second. I have one of this crafts, it's only 40 parts all stock except for the first stage which is 4 H250-32 and Engine plate with 3 MR-420 Methane engines but the stutter is SO bad even on the launchpad. If I launch the craft (which is a pain) it goes that way all the time until the moment I decouple that stage, immediately all the stutter disappears. Having less cryotanks (for instance) reduces stutter, adding makes it worse. Removing engines also helps but not fully. Also, that happens not with every craft, some have 100+ parts and it doesn't seem to affect it. I know it's not much but maybe any help how to debug this issue? UPD: I actually have another question for this one. The only reason I use CryoTanks for this one is because I cannot set Methane for usual Rockomax Jumbo-64, there is only Lqd Hydrogen option. Is that supposed to be that way, i.e. only hydrogen and no Methane for stock tanks? Edited July 16 by Ignalion Quote Link to comment Share on other sites More sharing options...

The only fuel is "liquid fuel", which is presumed to be RP-1 (kerosene). If you have a liquid hydrogen option for your fuel tank, that's coming from a mod.

Mhm, B9PartSwitch, it should be (should it?) the part of this mod. Anyway, I can edit tanks so I guess that's where it from. I can choose Cryogenic but it only has LiquidHidrogen but not Methane...

All I can say is that I have never had the problem you describe. Quote Link to comment Share on other sites More sharing options...
Cheesecake Posted July 16 Share Posted July 16 (edited) @IgnalionWhich Fuel-Switch-Mods do you have? CryoTanks? InterstellarFuelTanks? RealFuels? I think your stuttering are coming from another mod oder mod-incompatibility. A log and/or a modlist would be helpful.

urturino Posted September 26 Share Posted September 26 (edited) I love Cryogenic Engines, but i have a proposition for a minor modification. I also have CryoEngines Extensions and the mods work good together except for one tiny thing. The Sustainer Hydrolox Engine "Etna" have a worst vacuum ISP (410) than the Booster Hydrolox Engine Kunlun (412), which is also lighter. So there is no real reason to use the Etna over the Kunlun. Should we raise the Etna ISP a bit , maybe to 420 (still less than Fuji, but more than Kunlun and Arso)?

Should we raise the Etna ISP a bit , maybe to 420 (still less than Fuji, but more than Kunlun and Arso)? Hide contents Since the Kunlun comes with CryoEngines Extension, this should be adapted rather than the other way around. But the Etna has a different role than the Kunlun. The Kunlun is intended more for a conventional rocket, as it produces quite a lot of thrust at a low weight. The first rocket stage is dropped relatively early here. Therefore, the Isp in the atmo is higher here than with the Etna and the T/W ratio is also much better. A relatively powerful upper stage is also required here to get the payload into orbit. The Etna is used more like the Delta IV or Ariana 5/6 and has a rather poor T/W ratio. In most cases, boosters are required to support the launch. However, it should run as long as possible, while the upper stages are usually not as powerful. The first stage then brings the payload into orbit almost on its own, or at least to a very high orbit, where the weaker upper stage (as mentioned above), which then usually has a higher ISP and burn time, then has enough time to bring the payload to the desired orbit. For comparison: Delta IV Thrust of the first stage: 3140kn Burn time: 245s Thrust of the second stage: 110kn Isp: 462 Burn time: 850-1125s Falcon 9:Thrust of the first stage: 7600kn Burn time: 162s Thrust of the second stage: 934kn Isp: 348 Burn time: 397s Source: Wikipedia Edited September 26 by Cheesecake Quote Link to comment Share on other sites More sharing options...
IBIS-CELL Posted October 29 Share Posted October 29 Good day! I would like to inquire if you have any plans to add engines and an external air cooler similar to the HOTOL liquid air cycle engine, such as the Rolls-Royce RB545. Additionally, I am interested in a cooler for incoming air for further use as an oxidizer. Would you consider incorporating these technologies into your projects?
