Meters and mixes fuel and oxidiser into the chamber. Determines combustion efficiency and stability.
What decides the purchase: Element type (impinging, coaxial swirl, pintle) · element count · pressure drop · mixture ratio · faceplate cooling
Typical materials: Inconel 718, stainless 316L, copper alloy faceplates
Typical processes: Additive manufacture, EDM, precision drilling, vacuum brazing
What changes when it has to fly: Combustion instability is decided here. Acoustic cavities and baffles are design features, not add-ons.
