Rocket engine nozzle and method of fabricating a rocket engine nozzle using pressure brazing

A rocket engine nozzle comprising:

• a rocket engine nozzle jacket;
• and
• a rocket engine nozzle liner having a plurality of channels, the space between each channel defines a land, the rocket engine nozzle liner defines a forward endland and an aft endland, the rocket engine nozzle liner bonded to the rocket engine nozzle jacket by the forward endland and the aft endland bonded to the rocket engine nozzle jacket such that any space between the rocket engine nozzle jacket and the rocket engine nozzle liner is sealably enclosed, the lands being pressure brazed to the rocket engine nozzle jacket with a single pressure brazing operation, the bonds at the forward endland and the aft endland define closeout bonds.
