    • Great documentation. As a flight test engineer at Edwards AFB, this kind of stuff always interests me. Photo 16 could be a fuel line, but looks more like a hydraulic line. They usually don't use braided tubing for fuel lines. But then again, it's an old design, eh? Photo 33 is a good example of a fuel line. These engines sucked huge quantities of fuel, on the order of >50,000 ponds per hour! But they also use fuel as a hydraulic fluid and the fuel lines into the engine components themselves are relatively small, like the AB fuel lines in photo 48. Photo 36 looks like the engine's (a General Electric J79 turbojet) turbine section. You can tell by the high curvature of the blades. Photo 38 shows the compressor section up front. the rings wrapping the outer case are synch-rings, and they rotate the fixed blades within the engine (stators). In between each rotating disk is a stationary disk which have movable blades (rotating a few degrees about their perpendicular axis) to help with keeping the engine stable over a variety of airspeeds (different engine characteristics between low speed and high speed). The rear section is the turbine and the combustor is the collapsed section between the two. Photo 48 - depending on where these are determines if they are combustor or AB fuel lines. If they're in between the compressor and turbine, they're the combustor. If they're aft of the turbine, they're the AB. Photos 55-57 - the pressure vessel is an accumulator, most likely. They use these things for various reasons, mostly emergencies when the hydraulics are lost or to activate some kind of emergency power system. They'd use the high pressure air to spin up a generator or emergency power turbine or provide hydraulic muscle until the normal systems are back online. Again, great documentary. Hope this helps.
