World’s first crewed liquid hydrogen plane takes off::undefined
I like how you just assume that we haven’t advanced technology or safety features at all since the 1930s.
The space shuttle contain a huge reservoir of liquid hydrogen at very low temperature creating extremely difficult engineering stresses.
So, insurance cost will be sky high if ever such planes take commercial flights.
It also had 5 pressure vessels’ worth of liquid H2 for the fuel cells in the payload bay, sometimes more depending on the flight (and never had any issues wrt that, though of course it did present its own challenges). Challenger’s “failure mode” was in the SRB. The ET happened to be right next to it. We can talk about the ET and its direct impact on Columbia because the foam shedding was a problem with the ET. And of course, the issues with the NASA culture that were present for both.
I’m not going to wade into the semantics of explosive vs flammable argument further down because at the end of the day it’s semantics.
And I am an expert since you seem very intent on only experts partaking in this discussion.
I agree the SRB was the start of the huge explosion that somehow involved liquid hydrogen. I was posting that example because I was replying to an example where it was gaseous hydrogen combustion and because for the plane in the post it is liquid hydrogen which is used.
I don’t mind talking to non-expert as long as they don’t believe they know what they don’t know and do not insist they know better when they don’t.
From your comment I don’t know what “ET” means but I suppose “SRB” is something like side booster rocket solid rocket booster (?) I am not an expert of the space shuttle so please tell me if it pleases you to do so.
Do you know how brittle metals become at very low temperature ? Did you notice I did not talk about hydrogen explosiveness ?
But sure, let’s now talk about explosiveness. Do you know the mixture ratio range is completely different (much greater) for air + H2 explosive mixture as compared to other mixtures ? You are very far from an expert on the topic aren’t you ?
