It's a rocket so there is always a non-zero risk of explosion. This one is also a new, not-yet-launched rocket, making it extra non-zero chance of explosion.

- prox 4y agoA rocket is basically a controlled explosion, and when you stop controlling it, explosion is likely.
- capableweb 4y agoAh yes, just like fossil-fueled cars, but on a different scale :)
- sandworm101 4y agoNo. This is external combusion of cryogenic fuels at low pressures. There is no crossover beyond the fact that both involve rapid oxidation.
- QuadmasterXLII 4y agoA gas engine reaches about 1200 psi, a diesel reaches about 2500 psi. Raptor’s combustion chamber sits at 4500 psi. Which is completely nuts, even for a rocket engine. The F1 powering the saturn V only ran at 1000 psi. On the other hand, ANFO, a common low pressure explosive, has a detonation pressure of ~100,000 psi
- sandworm101 4y agoIts and apples and oranges comparison of combustion chambers. For purposes of combustion, the relavant pressure is the exaust of the rocket engine where combusion is complete. The burning gas within an ic engine is, at the point of combusion, at a very higher pressure. The ic equivalent of a rocket combusion chamber would be the blast wave starting at the spark, which then moves through the fuel. This difference become more important when discussing the new tech of pulse detonation rocket engines.
- capableweb 4y agoWhat is a fossil-engine if not a engine that does a bunch of small, controlled explosions very quickly? Sounds like they're identical to me ;)
- sandworm101 4y agoThis type of rocket doesnt use explosions. It burns fuel steadily. A car detonates fuel in packets. It is a different type of combustion.
