Jack Crossfire Registered User Thread OP	Discussion *More regenerative cooling prn Originally thought the nozzle wall was corrigated steel to make the exhaust flow straight & the hatbands did the cooling. Now U know they're just like organs. Making nozzles out of thousands of braze welded cooling tubes has been standard since the 1950's. Images View all Images in thread Views: 629 We did get shots of the cooling tubes in the F1 engine. Gas in this nozzle was contained by nothing but welds. Views: 307 They attached directly to the hatbands. Later on, someone realized they needed more reinforcement & welded on just enough steel jacket pieces. Views: 305 Notice they're tapered by welding 3 tiers of identical diameter tubes together instead of single tapered tubes like the SSME. The aft section was film cooled by preburner exhaust. Views: 283 The inner wall of the aft section bled preburner exhaust through injection slots between shingles. 1 ring of injection slots halfway down the nozzle wasn't enough. Views: 310 Cooling tubes on the J2 were also jacketless. The nozzle was just a bunch of cooling tubes & welds. Views: 249 Got lucky with the commute & Vika 1's bootloader started talking. Views: 244 Finished stuffing on both sides. Views: 254 Beauty soldering job. Views: 201** Aren't U glad U didn't need to pack this suitcase.
