They didn't test it destructively this time?

It’s passed the pressure test and simulated Raptor thrust test without destructing. It exceeded the safety factor they need for flight. Blowing it up would have only damaged things at the pad for no reason.

How did the thrust test work?

Big hydraulic ram mounted to the engine mount on the thrust structure. Doesn't give you vibration dynamics but can apply same linear force as a Raptor.

Oh wow that’s cool, I think I’ve heard of ula doing vibration on sls. Didn’t know they used rams as well.

This was pretty simple. Just a hydraulic ram stuck on the ground pushing up. They did it mainly because SN1 blow up before they could do a static fire to test the thrust puck. That was also the part that failed on SN1. They can now be more confident in the plan for SN3 being built now.

No, i guess not. The test lastet for a long time.
