Jupiter Tail Unit
This page serves as a repository for diagrams of the Jupiter tail section and its S-3D engine.
The original of this particular diagram was badly yellowed and faded, so these colors may differ from the colors of the original diagram.
The call-outs for the diagram are
I've got a number of similar, yet slightly different, diagrams of the Jupiter missile tail.
This diagram contains a number of dimensions concerning the Jupiter's tail unit. The diagram excludes the propellant tank and feed lines, but shows the pads on the forward end of the engine's thrust frame (where thrust from the engine is transmitted to the missile's airframe).
Also missing (oddly so) is the turbine exhaust duct and heat exchanger; it appears to have literally been erased from the diagram (lower left).
We see in this diagram that the aft skirt is 105 inches tall (the same as the diameter of the missile), that the engine extends 34 15/16" past the bottom of the tail, and that centerline of the S-3D's throat is 55.5375" from the nozzle exit, and that the S-3D is 98.21" tall, from the gimbal plane to the nozzle exit.
This particular diagram's original was in substantially poorer shape than the two above, and so this diagram is a bit rough-looking.
Here's diagram another diagram containing Jupiter tail unit dimensions. This diagram includes the LOX tank and propellant feed lines, the pads on the forward end of the engine's thrust frame, and the turbine exhaust duct and heat exchanger.
A few dimensions differ from the diagram above, but most of the differences are a matter of a fraction of an inch.
The original of this diagram, too, was in very poor shape. At first glance, this diagram looks like the one immediately above, but there are a number of differences. (If the diagrams had been alike save for the dimensional information, I might have saved the better part of a weekend, scraping away pixels to reveal an engine.)
