Thanks for some real data - not the usual anecdotes or unproven assertions.

However, If I read you thesis right, the propellors were windmilling almost frictionlessly. This is not the same case as I am interested in and I am not sure the results can be read across.

I am interested in a stopped prop versus one turning with the engine at idling speed. It is also slightly different to the often quoted case of a light plane with a dead engine but the prop windmilling in the airstream.

Any thoughts?

Thanks
