cold gas thrusters would do fine. unless they figure out how to counteract the ice build up or the problem that caused the vent that was stuck open cold gas thrusters or hot gas thrusters like what the old school boosters had would do fine.
Yeah I was laughing during the flight cuz Tim both put Elon on to using hot gas with his questions and diagnosed IFT-3's likely hot gas thruster failure in real time.
He comes back and Tims like maybe what might be a good is…. And Elon cuts him off puts his hands over his ears and goes na na na na im a not listening na na na
it was totally his fault yeah he definitely said "guys i got a great idea! put the hot gas thrusters on the ship!" yeah nah, he thought it was a dumb idea and Elon thought it was a good idea and since he has a room of yes men they just do whatever he says and now we're 3 flights in and all have had a catastrophic failure. they're testing their "the best part is no part" philosophy and so far they've only had to add parts that wouldve been suggested long ago.
It is quite funny but I highly doubt the engineers would allow the decision to go through if it wouldn't work, like someone else said it's probably that the vents simply froze over preventing the gas from leaving.
Most likely that the idea of Ullage thrusters on ship was already on the books to be implemented and all Tim did was double down and reinforce their idea.
Yeah as if Elon decides everything and doesn't listen to his engineers, I think the OP is actually playing the flute and thinks to be the genius of geniuses
Just so you know....They added more of them and The filters blocked up.....They then improved those filters and now it works just fine with some minor changes.
if the vessels are insulated according to the thermos principle, then there is not so much evaporation, because it partially turns back into a liquid state. during the shift, in the heat at TRZHK, I had to relieve the pressure once.
Thing is and always has been with Tim, he thinks deep down he’s competent enough to be an engineer (lol) and that he can give valid commentary about all the physical calculations and mechanical design of various rockets. He can’t. His graphs and other first-principle topics in videos are so dumbed down they mean nothing. In reality, he used to be a wedding photographer and has an art degree. I pointed this out under one of his videos (where he was trying to critique starship design decisions like a chief PE) and I got absolutely lambasted for it. The last thing giving him any credibility was this and the moon mission, but I’m really happy to see where both have ended up lmao. Screw that guy and screw all his fan girl subs that think he’s rocketry god bc Tim tricks them into thinking you can competently introduce design decisions over chief engineers without an engineering degree. I’m all for fans of space travel, but the people getting inside access to Boca Chica as ‘influencers’ explaining these concepts should be actual engineers or else they paint a poor picture of the reality of engineering. Otherwise, in my opinion as an engineer (grad 2021), they do injustice to how hard it really is to get a degree in and work in engineering positions on things like this
There might be a hundred different reasons for various failures with IFT3. Until SpaceX and the FAA have concluded their investigation we really can't be sure what the ultimate cause for failure was. Honestly we should wait before calling out people (yeah Tim gave the idea but it isn't a bad idea necessarily and some tweaks might fix this problem, which SpaceX engineers might just have overlooked. This is why the whole iterative design process works in the first place, by learning from their mistakes)
Isn't the difference between hot gas thrusters and cold gas that the cold just pushes out gas whereas the hot gas mixes and burns gasses to create the thrust?
Tim Dodd, The Everyday Astronaut, is not above self-reflection on the outcome of past ideas and decision when necessary. It is possible that the hot gas thruster might have been a factor in the loss of ship 28 during the IFT-3 test. If the Hot gas cooled and froze within one or more of the ACS exhaust vent, that may have caused the loss of attitude control. It is the unlikely that anyone could has foreseen this issue during the Starship design and development. This is why testing under Real World condition, an not just in CGI conditions is important. Better to FAIL a test than LOSE an important PAYLOAD or A CREW.
Well I wouldn't say the fact that they were using vented gas for attitude control was the main cause for the attitude control problems on IFT-3, the issue could have easily been something else. There are a lot of factors after all...
Lol, this was my very first thought when the ship was rolling around during IFT-3 that it was Tim's fault. However SpaceX have identified the issue and still believe in the idea, just beefed it up a bit for IFT-4
I wonder how it happened, that the booster used one system and the ship used another. Maybe there were two teams, and one of them thought of it and the other one didn't?
When the payload door opened the ship depressurized this caused the ship to lose control. This depressurized movement was why the door could not close.
@@ebenwaterman5858 The ship was pressurized otherwise it would have been crushed. As Ive heard many times from NSF that when the ship is not pressurized it's like an empty coke can.
It was pressurized in some way relative to space since it had smoke or some kind of gas swirling around in there that you could see rush out when they opened the payload door.
hahaha good one, however hot gas is not the problem, in space temps on average during the day around 120 to 125 Degrees Celsius, you boil rate is doubled that of what you get at sea level, Im sure space x knew to double or triple the size of your plumbing pipes and vents, was required but went with it anyways, also I doubt it was hot venting that caused Starship demise, it was cruising well below 200km, its exposed to atmospheric drag once engines where turned off ship began to turn,
The dor have bad mecanism, Tim idea is good , but make implement need work. In this F3 we see wath not work well and wath work well, back to work. My noob opinion.
I can see from the comments everyone loves this music, it makes me want to judge my ears out. I get the jab, it is funny, but...ouch. At least I now understand why grade school music teacher suicide rates are so high. 😐
What a terrible idea. Drastically complicate tank venting and if it fails in any way you lost your ship. Normally when you need something to be really reliable you reduce the amount of single points of failure and over-build the ones left over. Not everything needs to be reinvented.
