EX Motor question

Has anybody considered curing APCP under heat and vacuum/pressure? how much vacuum/pressure? I understand vacuum mixing......what about "pressing" at a known pressure to cure at a specific material density? wouldn't this technique get rid of voids? increasing material density would result in a much "harder" surface? should increase the propellant burn characteristics? ANybody done any experimental work in these areas?

Vacuum casting IS the way to go. It eliminates voids and maximizes density.

You vacuum before you pack. This still increases density.

I vacuum while I cast. It works very well.

How do you go about that??? Are you using a pourable propellant?

It "flows" rather than pours.
