General Question What does thruster ratings mean?

[orbitingpluto]

My problem is I want to calculate the delta-v of a rocket+rocket+payload in game, but looking in the object info box doesn't show a Isp value. There is a 'Thruster Ratings(vac)' line, but I'm not sure what those numbers mean. Could someone explain what to do to me?

Have you tried Burn Time Calc 2.0 MFD? It has all the data (almost all) that you would need.

I haven't. Could be useful, so I'll try it out.

its really useful, more than it seems at first, it gives dV for the vessel AND stack (including attachments made with UCD ), gives all the engine data that orbiter needs, im using it now to refine the engine parameters of my lunar booster (in the making )

I only spent a few moments trying it out, but I already like it:thumbup:. Thanks!
