A start mechanism ignitor for a propulsion system combustor comprising:
- a propellant cartridge comprising cartridge walls forming a cartridge interior, an interface formed within the cartridge interior separating a first chamber from a second chamber within the cartridge interior;
- a propellant material disposed within the cartridge interior;
- and
- an ignition chamber fluidly coupled with the cartridge interior.
A propulsion system having a start mechanism ignitor comprising:
- a case supporting a combustion section having a combustor, the combustor including a combustor casing;
- a fuel injector attached to the combustor casing;
- a propellant cartridge attached to the case, the cartridge comprising cartridge walls forming a cartridge interior;
- an interface formed within the cartridge interior separating a first chamber from a second chamber within the cartridge interior;
- and
- a propellant material disposed within the cartridge interior, wherein the cartridge interior is fluidly coupled with the combustor.
