I am presently reading "Challenger: A True Story of Heroism and Disaster on the Edge of Space" by Adam Higgenbotham. I have reached the part during the months leading up to the Challenger launch when various engineers developed serious doubts about the solid rocket booster O-ring seals. (Actually, we should call it the "solid-FUELED rocket booster.") This is a stupendous addition to that tale, with the detailed descriptions of the booster operations -- along with visual portrayals of the equipment. P.S. The solid fuel in the boosters, a combination of mixtures and compounds, had the approximate consistency of a pencil eraser. Just an interesting little factoid.
@@mr.ackermann807 You need to take into consideration the temperature of the burning fuel. If you also add cooling then you decrease the volume for fuel and will therefore need longer/bigger rockets to produce the same thrust. Larger rockets with cooling will add a lot of extra weight and therefore more thrust will be needed. The extra thrust will need to come from more fuel…. It a compounding problem where more fuel will be needed at the end and much more money/resources will need to be invested/spent for a single launch. This method of getting things into space is already expensive as it, making it more expensive is suboptimal.
@alh3328 I already know it is expensive enough as it is. And thank you for reminding me of the temperature, so most metals or alloys would be a problem. The other method that I can think of is stage burning where as 1 finishes it burns the next but the problem again is the temperature plus I think that's technically what happens anyway just not controlled staging burning. I was also aware of the mass to fuel ratio for needing more rockets for better cooling, so ok. I'm still constantly learning and willing to take criticism and advance, so for that thank you for your input.
One contractor did submit designs for single-piece SRBs. The challenges of shipping something that huge to the Cape, plus the cost drove the decision to go with Morton-Thiokol's segmented design.
sorry for not uploading videos for a long time.
if you like the video subscribe to my channel. THANK YOU.
You should have showed the team of scuba divers inserting the 1,500 lb watertight plug attached to an air hose for the dewatering process.

Excellent description, well done! I have subscribed and look forward to your future videos.
Excellent detailed video. Hope to see next part.
Glad you liked it!
Very well-explained.
Thank you
Very well done video
THIS IS SO COOL! Subscribed!
Thanks
Don't thank me, you're the one making this great content!! THANK YOU!@@immersiveengineering
cool!
thanks
Where’s the next part? Love the video
i love to make one, but it takes a lot of time and these videos are not getting much views. but thanks for subscribing.

Thanks
Are you sure theres is no way of stopping or even throttling it?
There is no way to stop them or throttled as far as the ones which are in use.
@immersiveengineering what about sectioning them like rotating cylinders with gaps?

How come they weren't made in one piece? Would have prevented challenger explosion if made in one piece, no?
I think its hard to manufacture and transport a long one piece and it is easy inspect for any issues
each section must be xrayed for inspection after fuel has hardened.

@@scottschoppert9149 Transportation. Their diameter was also affected by this. They had to be right right size to fit on rail cars.
