I had previously explained the use of Nitrous Oxide (N₂O) + Acetylene (C₂H₂) as Rocket Fuel. The major drawback of this fuel is high soot formation on the nozzle which reduces the performance. Directed electric fields reduce the formation of soot. There are scientific researches on that topic. However, they are not applied to rocketry as far as I know.
Recent progress in electric-field assisted combustion
I am in favor of rocket designs that do not require complex turbo pumps. High vapor pressured nature of the Nitrous Oxide + Acetylene simplifies the rocket design considerably even though needing some additional adjustment points which are not that complex to implement.
Acetylene is more expensive than liquid natural gas. I believe this engine design is more reliable than the turbopumps which increases the rocket reusability and compensates for the higher cost of the fuel.
