DAL59 Posted October 2, 2022 Share Posted October 2, 2022 It would be nice to have built in options for ullage, limited ignitions, limited throttle depth, RTG decay, boil-off, construction taking time, ect. These should be off by default and in the difficulty settings. Link to comment Share on other sites More sharing options...

But I do think that for some of them it's just not practical due to the work needed to implement them well enough and the operating resources needed.

Does boil-off affect Deuterium and Helium-3? Would such an engine have limited ignitions? Given the control over the fuel pellet fire rate, would there be a limited throttle depth?

darthgently Posted October 3, 2022 Share Posted October 3, 2022 (edited) Solar pressure affecting craft over time, smooth decrease in atmosphere pressure instead of sudden disappearance of all drag with varying height of atmosphere depending on solar wind, uneven gravity over different areas of bodies, solar flares and storms, heliosphere, cosmic rays, income taxes, car jackers, oh wait. I've wandered again Edited October 3, 2022 by darthgently Link to comment Share on other sites More sharing options...

As I understand it, the available number of engine ignitions is based on the available amount of spin up fuel (typically hypergolic or monopropellant) available to get the turbines for normal combustion engines spinning to generate enough feed through for normal operation to keep everything moving, like a car starter. So I don't think fusion or fission pellet designs would really have ignition limits so long as electricity is available. Also, Ill honestly be a bit sad if you can run an orion drive at 1% throttle instead of it having a more set impulse per pellet explosion Edited October 4, 2022 by mcwaffles2003 Link to comment Share on other sites More sharing options...

bajtec Posted October 13, 2022 Share Posted October 13, 2022 There is already excellent mod community around RO (Realism overhaul) and RP-1 (Real progression) that implements them pretty nicely - maybe inspiration, cooperation ? Link to comment Share on other sites More sharing options...
regex Posted October 23, 2022 Share Posted October 23, 2022 Reaction wheel saturation would be cool, also reaction wheels being much less torquey than they are in KSP1. Link to comment Share on other sites More sharing options...

Wouldn't it be just as bumpy just he bumps are less frequent? It's not like the nukes are pushing the pusher plate any differently. Link to comment Share on other sites More sharing options...

The piston plate should be exerting force on the ship the whole time, and just before it reaches the end of the piston and snaps back, the new bomb pushes it. If you don't detonate a new bomb by that time, the piston reaches the end of its extension and the front of the ship is jerked backwards a few m/s.

I get what you're getting at, I think a dampener could prevent that kind of jostling but I definitely see the logic in what you are pointing out, especially if the plate hits a hard stop at full extension.
