Turbine

Like everything else about the F-1, the turbine is huge. I've seen a turbine from a WW II-era torpedo, a V-2 turbopump turbine, and a Mark 3 turbopump turbine, which are all roughly the same size (Mark Wells of ROCKETRELICS.ORG tells me that the Mark 3 turbopump turbine wheel is approximately 10 3/16" inches in diameter).

The F-1's turbine discs are much larger, although I've never been able to find the diameter of the turbine wheels; the closest I've found is that the F-1's Mark 10 turbopump is described as a "35-inch turbopump" (this in documentation for the F-1A, which would have had a "30-inch turbopump"). Each wheel has a slightly different diameter, so it's unclear whether the first-stage wheel, the second-stage wheel, or perhaps the turbine housing is 35 inches.

The turbine was separated into four main parts: The turbine housing, the shaft, the first-stage turbine wheel, and the second-stage turbine wheel.

The turbine components (other than the shaft) were covered in black soot. In order to bring out the detail, I had to use a fairly long exposure. This makes many of the components look less black than they really are.
