Why not use an oxidizer on jet engines, wouldn’t it provide better efficiency/power output?
In: Engineering
It would not improve efficiency. In fact, you’d roughly halve your efficiency. This is because you need twice as much ‘fuel’ to get the same energy. Also, your engines are definitely going to melt. Lastly, power output is not at all the limiting factor on jet engines. We can make some wicked powerful engines, but they aren’t as efficient. Typically low-bypass turbofans or turbojets provide radically more power than the high-bypass engines you’re probably used to seeing, but they ‘waste’ most of that energy by yeeting their exhaust way faster than they have to. They become more efficient at higher speeds, as they *have* to yeet their exhaust faster, but at higher speeds drag becomes more of a problem. As such, jet engine power output is currently very well optimized for efficiency.
