Many companies are hiring exceeding under qualified people on the premise of it pleasing their HR who work for the CFO, who works for shareholders. BPS Space is likely more qualified than many of the employees at Northrop Grumman ..He is accountable to millions. They are accountable to (almost) no one.

Oh, and since you asked, not only is there in fact a very slight contour to the SLS SRB nozzles, there’s a very slight contour to the Shuttle SRB nozzles too. It’s difficult to notice especially with the aft skirt in the way, but it’s visible in cross section in quite a few documents available from nasa

When I saw this „observation “ the first time (in Scott manleys vid of course) literally the first thing I thought was BPS?!?? You managed to link solid rockt motors and nozzles (and maybe unscheduled… rocket stuff ;) in my brain directly to your projects … impressive

[@mojaverockets]

I'm glad you mentioned these two things that I've been saying for years, hotter ambient temperatures cause solid propellant to burn faster (as much as 25-30%) that increases chamber pressure and that the nozzle end of the motor needs to fail first. When screwing on end closures the forward bulkhead end should be screwed in all the way and the nozzle end can be a thread or two out (some people do it just the opposite). On bolted motors, the nozzle end should have fewer bolts. On our 12" diameter solid motors, we bolted the divergent cone on the exterior with the throat smaller in diameter than the inserted divergent cone so that if it blows, the throat effectively increases in area as much as 50% decreasing chamber pressure. We've never lost a forward bulkhead doing these things.

[@thedarkside13]

I saw a comment someone have asked Tory "Can we get a trajectory of the nozzle?" Tory's answer was "down." 😂😂😂😂

Nice one, using kgf as Unit - "Imperializing" the metric system. 😂 I was expecting Newtons as Unit for Force. Wikipedia: The kilogram-force (kgf or kgF), or kilopond (kp, from Latin: pondus, lit. 'weight'), is a non-standard gravitational metric unit of force. It is not accepted for use with the International System of Units (SI)[1] and is deprecated for most uses

The lesson that I take from the submarine failure is that when your safety monitoring sensors give a loud signal it might be good to listen carefully and take appropriate action, like don't ignore it because it is inconvenient. Good advice in general when doing dangerous things.

The SLS booster nozzles are absolutely 100% not conical. You can look up the cross section online. Parabolic isn’t totally accurate either as the shape is determined by method of characteristics at these levels of performance.

[@faroncobb6040]

I found the video both funny and informative. In particular the bit about the three degree cant being the difference between success and failure was something I hadn't heard anywhere else. The one thing I would have liked to have seen would have been a discussion on the effect of altitude on the effectiveness of the nozzle. While it may only add 20% to the efficiency of the rocket at or near sea level, I suspect that as you climb out of the atmosphere the sideways expansion of the rocket plume will increase enough to noticeably degrade the performance of a rocket that has lost its nozzle.

Also doing the math to spread that loss of thrust it accounts for about 3-4% less. According to wikipedia that configuration can put 14400 kg to a heliocentric orbit and the mission payload was only 1500 kg. So lots of mission margin. In fact they shouldn't have even needed the SRBs for mission success, but it was also an integrated system demonstration.
