What he is saying is that, cool though it may be, it doesn't actually add any insight to the discussion that was taking place.
Aero51 said:And on the topic of this thread: I was reading a paper recently with regards to hypervelocity projectiles launched from a RAM accelerator. Based on the tests that were carried out at standard sealevel temperatures and pressures, some metals (aluminum and magnesium alloys) will actually oxidize and ignite. These tests were carried out with M ~ 6. It was also postulated that titanium would oxidize and react with the fuel air mixture at higher velocities. The name of the paper is:
[Ram Accelerator Operating Limits, Part 2: Nature of Observed Limits]

Its a very fascinating topic!
That reminds me of the flame generated on the projectiles fired from the Navy's experimental rail gun.
