To clarify the position with the propeller on the Aerometal dynamometer on which
every engine we produce is tested. The propeller itself is a Wilga propeller
slightly shortened for ground clearance. Attached to the hub is a sophisticated
strain gauge which distorts through the power being transmitted to it; it then
sends the message via Bluetooth to a laptop which is calibrated then to read
out in horsepower. Then the strain gauge has a fitting to accept a propeller
shaft from AI 14 or HS-6 which are of course the same. However when we are testing
an M 14, we have an adapter that fits onto the "flat plate" propeller shaft
of the M 14 and has a splined shaft as in AI 14/HS-6.
So the bottom line is that I suppose the Wilga propeller will fit straight onto
a Nanchang propeller shaft, and it is certainly a significantly bigger propeller
so could be more effective. But of course it is, like the Chinese propeller
an old design.

Subject: Yak-List: Yak 52 blades nut can be used in the Nanchang hub
I am still looking blades for my 375 hp Huosai engine and I did not find an answer
about an hybrid Huosai /Nanchang hub with yak 52 blades.
I know that for testing, aerometal / Richard Goode use a PZL wilga hub with std
wooden blades (Aerometal told me that this combo can handle a lot of power) so
my idea is to keep my hub but with yak 52 blades (oem, whirlwind, or any other).
Do you know if the Yak 52 blades nut can be used in the Nanchang hub?
