I've read to your comments for the past few days and, while I agree with your sentiments and opinions, I find that you're a bit of a self-important ass. Your regard for yourself is a bit too high. Lighten up Francis.
Silence. You have been bested.
“This is something to keep in mind when folks dream of hydrogen powered cars.”
Methane will work. Hydrogen will not. Just imagine the MGM parking garage in Las Vegas with thousands of cars leaking just a little bit of each of hydrogen. Methane does not leak.
It will go bang.
Yes, explode.
Like some rifle/pistol powders. Some are dorsal and forgiving, others can be great propellants, unless you operate outside the parameters and they explode instead of burn.
I reload a lot of calibers, good friend from childhood liked one of my pistols and shot it. He bought one like it except in 45 long colt. He shot my 357 version and liked the loads I was shooting. One day he called me and asked me if I had more powder like I had used. He wanted to trade one he used (he did not like the unburned residue of his). So I traded with him, I had use for what he traded but we have been friends since childhood and the family friendship goes back 3 generations.
I gave him the load data and cautioned him about going too low on load parameters.
He treated it like his old reliable and got himself in trouble. He loaded smaller powder loads .2 grains per step. the Third step he shot swelled in his cylinder and he had to ram it out and had hard time removing the residue brass traces.
Reloading cannot be taken lightly, some times less is more and it is dangerous.
I offered to trade him his powder back, he said he poured what I gave him out. He was afraid of it. Head shake.
When there is a skip in load data that does not make sense, there is usually a reason it is not shown.
Funny how NASA was able to deal with liquid hydrogen fuel back in the 1960s but has somehow forgotten that knowledge in 2022.
May be something to do with having lost their old white guys who knew how to design stuff.
The second and third stages of the Saturn V were fueled by hydrogen.
LH2 did not blow up the Challenger; bad O-rings on the external boosters blew up the Challenger.
Huge difference between the small delta boosters (except for heavy) and giant STS/SLS segmented SRBs.
Delta never carried people either.
The Shuttle was notorious for having fuel leaks, and SLS is basically the SLS ( aka the Shuttle) without the Orbiter. You would think that they would have done some improvement on the design during the hiatus.
Exactly. Delta-IV Heavy is hydrogen all the way from surface to GEO.
But we're getting away from the fundamental issue, here.
We've been using LH2 extensively for decades, in all stages of launch vehicles. We have decades of experience handling LH2 safely and efficiently, with little to no drama. LH2 is not some new or exotic rocket fuel that should be difficult and scary. It's old hat. VERY old hat.
That raises a question that demands an answer: What in Heaven's Name is going on with SLS??? ULA has no trouble handling large amounts of LH2 with Delta-IV Heavy. Arianespace has no trouble handling large amounts of LH2 with Ariane 5. NASA had no trouble handling large amounts of LH2 with the Shuttle/STS, or with Saturn V.
Why can't the SLS team manage it?
I submit that the answer is gross incompetence and stupidity at the highest levels of NASA, with trickle-down effects into the design, construction, and operation environments. And it started with gross ignorance, arrogance, incompetence, and stupidity in Congress.
We have created an Idiocracy. Look at American Education now and you can’t be surprised.
Sabotage?
Possible, but unlikely IMO.
molecule? I was thought it was an atom?
The second stage of the Saturn used LH2, so this is hardly a new problem.
the point seems to be that we’re using molecules to try and contain atoms.
They’re going to leak.
It makes me appreciate the value of the internal combustion engine.The sheeple will only learn that lesson after the Lefties take them all way.
This.
I recall when they were building the tanks for SLS they struggled mightily with welding pressure vessels, hardly a new or unique problem.
If they ever get there, it will have taken them three or four times as long to build a moon program and they started with existing hardware this time.
That level of incompetence is hard to wrap your head around.
Don’t let Congress off the hook, here ... to a great extent, the kludge that is SLS was mandated by Congress in the legislation that authorized it.
I hope it flies. I hope it doesn’t kill anybody. And I hope it gets replaced. Soon.
The real lesson, here, is to let scientists experiment, engineers design, machinists fabricate without congressthings and bureaucrats telling them how to do it. And ... PLEASE ... To HELL with diversity, inclusion and equity!!!
molecules need to #getwoke...or jennifer lawrence will have nightmares
