Personally I think they should have left it uncovered, but I don't think it really matters what it is covered with.
It's made of some pretty beefy looking stainless steel under all that.

No time now but 70% (followed by dead silence) vs lifting a battleship and preparing to do a lot more this year and the coming one. Raptor was supposedly behind, now it's far far ahead by all metrics. I wish I had saved the BO employee rants against raptor some years ago.

>> No.10849325

>>10849319
I wouldn't consider that "beaten", for one the BE-4s development schedule is different from the Raptor. Theres the fact that the BE-4 is intentionally being undersigned so it can have more upgrade potential. The lower chamber pressure compared to Raptor can improve reliability as well. It's turbo system is simpler than the Raptor too.

Plus there's the fact that Blue Origin is super quiet about everything they do. So it's no surprise that they haven't said anything about their engines for a while.

Interesting to think about what could have been if America continued with the bigger engine = better rocket philosophy. A single M1 on the Saturn IV 2nd stage would produce 130% the thrust of the cluster of 5 J-2 engines used on the actual stage. That means they could have stretched the tanks by that 30% to get the same initial TWR, resulting in a much bigger 2nd stage that also had slightly better Isp (428 vs 421). Adjust the first stage to have 6 F-1 engines instead of 5, or go full Nova and jack it up to 8 F-1 engines, and you'd have a rocket comfortably capable of direct-ascent Moon missions. Hell, why not go full retard and have a 16 meter wide core stage with 2 M-1 engines assisted by two liquid fuel strap-on boosters with 5 F-1 engines on each booster?

Also, when the iron curtain came down and American scientists were able to have a look at the oxygen rich staged combustion engines Russia had developed, they should have taken that technology and married it to their giant-as-fuck engine experience and made a single-chamber version of the RD-170, and to add to that they should have done a huge oxygen-rich staged combustion hydrolox engine, too. Call them the F-2 and M-2 engines and build a fuckoff LARGE rocket for NASA, and a couple smaller rockets for the commercial sector (like Atlas V and Delta IV, but thiccer).

They haven't flown a single BE-4. Why? They can't get it to run properly. They scrapped their turbo pump design and started over on it because their first iteration couldn't keep up with fuel demand.
The whole system is much more simple because its not as efficient as raptor.
Its also much larger but less powerful.

Its been in design and testing stages much longer than raptor, yet not a single one has flown anything.

Doesn't really matter, since the risk of exploding comes from the engine itself ingesting a piece of FOD.

that too, but the hard part of the whole welding it in a field behind a shed tent of Starship is making the welds strong enough while being light enough
