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.COM 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 -- 35 inches for the second-stage turbine wheel. I seem to recall that the first-stage turbine wheel is 32 inches, although I can't seem to find any documentation to support this (perhaps one of our hosts mentioned this?).

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.
