GLAST Launch Flames
« on: 08/10/2008 08:51 pm »
So, I downloaded the GLAST launch in 720p, and was noticing how scorched the rocket was, on account of the flames shooting straight up the length of it after ignition!
Isn't the point of a flame trench to deflect the flames away from the rocket?

This was discussed in the following message and thread.

It is exhaust, not flames, that flow upward briefly through a set of louvered exhaust ports on the top side of a long flame duct that was added to SLC 17B during the late 1990s for Delta III.  The flow stops after the solids build up full thrust.

That was pretty crazy to see how "flame kissed" the rocket looked as it left the ground.
