TerryD Sorry for the delay in responding to your query. The buckets on a Stumpf turbine are ‘U’ shaped. The steam (or air) is directed down one side of the U and goes round the bottom of the ‘U’ and out the other side. A Pelton wheel which is specifically designed to work with water which has a large ‘Head’ but smallish volume. Its buckets are a ‘W’ shaped. It is a sort of double Stumpf.


There is one point about the Stumpf wheel. It was used on most air driven Gyroscopic aircraft instruments. The instrument’s case was ‘airtight’ and was evacuated by a venturi mounted outside in the airstream. Air was allowed into the casing through one or generally two nozzles. This simple arrangement gave them enough speed to do their business, but no power was drawn from them. From memory they were generally over 2 ½” in diameter and often over ¾” wide. The buckets were milled quite deep (well over 1/8” deep) and relatively few in number.


Michael Yes, but I had a large IBM that I could use and wrote in Fortran4

Hi Richard,
 
Thanks for that explanation, I think that I now understand the processes involved.
 
Best regards

This is the inside of an aircraft gyro, it has 24 buckets 1/2" across, and 1/16" deep. There are 2 inlets, 180 deg apart. Great what you find in the junk box. Ian S C
