oxidizer uses RGHP and the fuel is NOT petroleum-based (e.g. RP1,
Kerosene, etc.).
I take it RGHP is "rocket grade hydrogen peroxide"?
To me, the main market for hypergolics seems like it's orbital
maneuvering. Brief pulses of thrust which have to be precise are a
scenario where self-ignition can be a big plus, and since less fuel is
involved, fuel cost is less of an issue. For most uses, though, torch
igniters seem quite satisfactory.
