Redstone Early Steam Generator

Among Mark Wells' collection is an early Redstone rocket engine steam generator. It has been disassembled, with the top cover and the lower shell separated.

The steam generator is used by the engine to drive the turbopumps; it is analogous to the the gas generator on later rocket engines. The steam generator works by decomposing hydrogen peroxide, supplied from a tank mounted on thrust frame at the forward end of the engine, into steam.

This is shaped differently than later version of the steam generator and, according to several sources, used 36 cobalt screens (of which he still has five) to decompose the hydrogen peroxide rather than potassium permanganate pellets.

Additional information about this version of the steam generator can be found starting at approximately 1:01 in this YouTube video. The engine shown in this video appears to be an A-6 or earlier (the A-7 had a single fuel line leading from the turbopump to the fuel inlet manifold near the engine's exit plane), so I don't know whether conclusions may be drawn regarding matching this type of steam generator to particular engine models.

I also have a page regarding the Redstone steam generator, albeit the later model with the potassium permanganate pellets.
