slidebite posted:Off topic, but black sockets suck. They look all neato and fancy until you drop it when you're working on something and it doesn't hit the floor. Commence search for an hour... looking for something jet black in all the shadows, nooks and crannies. I have fluorescent pink and yellow paint pens I mark all my tools with. It helps me find them, but I also work with other people at stage rallies and whatnot, makes it a lot easier to sort out who owns which tools at the end of a job.

Looks a bit like a Windsor from the timing/water pump flanges, though it would have to be a custom block if it was (no stock Windsor was ever aluminum 4 bolt main that I know of). Not that aftermarket blocks are uncommon in high end marine stuff anyway.

Almost certainly an aluminum "racing" engine of some sort, given the threaded freeze plugs and such, though it appears to be cast rather than billet.

My buddy shared with me the plan to do a bellyflop approach with a last minute rotation and landing earlier today, and I got really excited at the possibility of a big boom. It did not disappoint.

CAT INTERCEPTOR posted:Wrong thread. The entire launch / belly flop and Rapid Unscheduled Disassembly was absolutly AWESOME I'm told that the green flame indicates and Engine Rich Exhaust, as well. One of the engines banged into another one on the way up, and didn't reignite for the landing. You can see it the engines wiggle around T +1:40, and one engine go out, then the all of them wobble and the second go out @ ~T +3:15.Point is, though, that it lifted successfully and made its altitude. SpaceX had a live feed that I watched slightly behind actually live, since YT decided to pause for some reason just before the launch: https://www.youtube.com/watch?v=ap-BkkrRg-o

The engine shut downs on the way up were planned. The extreme gymballing was to orient the rocket so that the remaining engines would thrust through the center of mass. The only thing that did not work was the propulsive landing. It was even dead center on target.

Sagebrush posted:That would make sense, as green flames are characteristic of copper compounds, and many rocket engines contain copper parts for their thermal qualities According to Scott Manley, the engine rich exhaust was probably caused by low fuel system pressure at the very end, which lead to a very lean, oxygen-rich, engine-rich combustion. https://www.youtube.com/watch?v=egHxiX40eJY

Safety Dance posted:According to Scott Manley, the engine rich exhaust was probably caused by low fuel system pressure at the very end, which lead to a very lean, oxygen-rich, engine-rich combustion. Yeah. Super lean conditions get crazy hot and burn up engine parts. Makes sense. It was amazing to watch. Musk is a Grade-A rear end in a top hat, but he's managed to accomplish an incredible amount. I'm conflicted. SpaceX is accomplishing tasks in months or years that would take NASA decades. Reuse has gone from a pipe dream (and no the shuttle and SRBs don't count) to a non-news story. Full flow staged combustion has gone from a "never-left-the-ground" idea to a flying rocket with multiple engine ignitions, crazy gimbal control, deep-throttling reality.

sharkytm posted:Yeah. Super lean conditions get crazy hot and burn up engine parts. Makes sense. SpaceX should get a lot of credit for pushing forward space travel as a whole, it's forced ULA to try and actually compete instead of lobbing satellites into space for $Texas on ancient ICBM technology, and companies like Blue Origin are coming up fast in the race. The NASA thing is really sad, and a lot of it seems to boil down to every new administration taking whatever they're working on, chucking it in the trash and telling them to develop something new.

musk is a grade-a rear end in a top hat and also a colossal dipshit; spacex's successes aren't due to him, they're due to the actually competent people who are desperately trying to keep elon "no cases by april or whatever dumb poo poo he said" musk from meddling tesla doesn't do that and it's why they have cars that accelerate into firetrucks so they can transform into fire elementals

Momma Shotwell runs SpaceX and it shows. Tesla would be an actually cool company if they could get musk away from it. It runs purely on hype.

I thought the flying water tower was how they distract Musk and keep him from loving with the real rockets that take people into space. Although I remember seeing something recently about how the SpaceX flights are a lot more expensive than previously planned upon so maybe reusable rockets that land doesn't get you anything. Don't quote me on the details on that, I'll have to find it later.

I'm an aerospace guy and have a bunch of close friends who work there. The LA facility is super nice and the folks that work there are serious and do amazing work on tight time-frames. Texas is a career death sentence unless you are in engine development. I think that all stems from https://en.m.wikipedia.org/wiki/Gwynne_Shotwell
