Like a D500-P for boost glider drag races. 8-)

Or is that a -0?

It would have to be -P I was confused about the warp-9 propellant and that they were all plugged so I asked a vendor selling them (RedArrow) He answered that they burn so fast, it creates kind of a vaccum in the motor and sucks out the delay. I thought he meant that it snuffs out the delay while it is burning, but he really meant it pulls the delay out of the fore closure. He said he has seen it sometimes made it into the nozzle.
Now...I would LOVE to see a D500-P but I think it'd be closer to a D75-P(wild guess at the number) as there is already a G339-P (38mm, single grain) It would still shread just about any MPR out there.

First, don't take anything with a 8-) to seriously.
Second, don't BG's usually use a -0 to spit the motor out and to move the wings into glidining position?
As for tech details or Warp-9, who cares, I was discussing an imaginary product so anything is possible when it isn't real.

No, that would be impossible. Motors create pressure, not vacuum. What is really occurring is that the slower burning delay grain is getting snuffed out by the abrupt pressure drop at the end of the burn. This is similar to what happens when a motor chuffs on the pad.
If the delay grain is really pulling out of the forward closure, it is due to the high g's that this propellant formula can generate in certain rockets.

No, it is possible. At burnout, mass flow exiting the nozzle will create a momentary vacuum.

I've done and seen lots of pressure testing of rocket motors. I've never seen one pull a vacuum at burnout, or anything less than atmospheric pressure.
Maybe Gary R. could provide some input here. I know he's seen a fair share of motor testing.

A paper airplane maybe! What would the burn time be, .001 seconds?

I'm not inclined to get L1 certified just for L1's sake.
Maybe if we actually get a D500-P certified... Naybe when the BATFE rolls over, I'll cert just to celebrate.
