  1. isnt temp directly proportional reactor power/exaust cooling? (assuming heat capacity is insignificant...)
  2. fair point. throttle would control propellant flow, meaning thrust would stabilize at the throttle level under automatic control but would take a while to respond to throttle changes, and would be at the proper throttle level under manual as long as the proper temp was maintained, but you might be right, maybe too decoupled. out of curiosity, how is thrust calced now? ive mostly been concerned with ISP, but is thrust not decoupled from throttle currently, due to the reactor taking time to increase power?
  3. sorry, thats more or less what I meant, wasnt communicated clearly. So, having not worked with unity/ksp modding at all (my small background is in scientific computing, not game dev), take what Im saying with a massive pile of salt... but what if the ISP depended on the core temp, core temp was regulated by system heat the normal way (via reactor power and radiator+exhaust cooling, though some engines might have a fraction of waste heat that can only be cooled by radiators, not exhaust), and the thrust was dependent on ISP and mass flow (all via the equations we already have/c
  4. reactor power and mass flow determine thrust, yes, but the core temp should be what determines ISP. http://www.projectrho.com/public_html/rocket/enginelist2.php#id--Nuclear_Thermal
  5. just tested that, and the ISP definitly depends on the reactor power setting, rather than the reatctors core temp. heres it at full throttle, I let the temp stabilize. and at roughly half throttle, same reactor temp. I also messed around with manual reactor control a bit, and confirmed that the ISP indeed depended on the reactor power setting. I put some radiators on to absorb the waste heat, and set the throttle to a low setting, and messed with the reactor power setting. At full power, full ISP was achived. at half power, you get roughtly half I
  6. Shouldn't the ISP of the engine rely on the core temperature, rather than the throttle? Ive noticed that if Im at anything less than full throttle, my ISP is limited even if the reactor has fully 'caught up' to my throttle position and the core temp is where it should be. I like that I need to adjust the throttle slowly so I don't quench the reactor cold or burn it up, but it doesn't feel right to be getting half ISP at lower throttle/thrust limiter. (At least, I don't think that's how it works, and definitely not with any other engines in KSP.)
  7. does the ISP of the engine depend at all on the reactor power? am I 'wasting' propellant while throttling up and down?
  8. will the nuclear transfer improvements be available for parts not covered by systemHeat? I currently use the old NFE system to let my engineers do things like transfer solid fuel/refurbish ablator, wondering if I will be able to switch this over to the new system.
  9. Id love this. Not a full fledged mechJeb, but still able to automate long burns. Id also love if it had a preset way to simply execute a manuver node, no extra frills. (so a single 'execute manuver' button). I can use MJ for it, but I dont like having a 'do everything for me' autopilot on top of it.
  10. the url in the version file points to a non-existant thread, FYI.
  11. thanks. I finaly updated to 1.11 and could not reproduce... of course I dont have US installed...
  12. Havent updated to 1.11 yet, but could I get your ModuleManager.ConfigCache (in your gamedata) and the modulemanager log (located in the ksp root directory under /Logs/ModuleManager/ModuleManager.log)?
  13. developing the same craft (switched to nuke reactor), and found another one. the bussard scoop doesnt seem to work. screenie and log attached. log (I am exceeding the maxlength on normal pastebin!)
