Propellant properties mistakes

[NAOS-PUPPIS]

The data for the propellants DX and SB in the editor are not correct (burn rate coefficient) according to Nakka data

I agree, it seems to round to 0 when using metric units. Also KNSB and KNDX seems to have been swapped? But I am not sure I have not compared to actual Nakka data.

Interesting. That said, Nakka has multiple sets of data for many formulas, and I honestly think some of the piece-wise ones are just overfitting a small characterization run so I'm skeptical of his data. If anyone sends me a difference source for sugar propellant regression data I might switch over to that for the next oM version.
