My copy of QL came out just before they added RL-17. Can someone send me a copy of the R17 data from the powder file?

Heat of Explosion / Potential:
Ratio of Specific Heats:
Burning Rate Factor Ba:
Pro or Degressivity Factor a0:
Progressive Burning Limit z1:
Factor b:
Propellent Solid Density:

Thanks,
Greg

Based on my experience, the current characterization does not seem to wholly account for the homogeneous deterrent but seems to treat it as a conventional powder. It is predicting higher pressures than I am seeing. QL is not so far off that it is not useful. Once I was aware of the "offset", I could still make reasonable load predictions.

Thanks for the help.

Travelor,

I already bought the upgrade and my version is the current version. They added RL-17 literally a week after they sent mine out.
