More Testing

Here are three more videos of DMLS Chamber testing. The first two are long duration tests of the regen cooling:







This second long duration video is at a slightly higher O/F ratio, thus resulting in a lower flame temperature and reduced heating of the chamber walls.







In the last video, I was experimenting with camera settings trying to better capture the plume color and Mach diamonds. It didn't work too well. What did work well was the multiple starts/stops on chamber. Each stop/start is commanded remotely.
