Antonov An-2
This is a picture I recently made in Atyrau (Kazakhstan) in the Victory
Park. It is an open air museum dedicated to all people who fought and often died in various wars. The picture shows the business end of an An-2. Does anybody know what the purpose is of the objects attached to the roots of the propeller blades? Kind regards, Herman

Those are counter weights that help control the constant speed props. Hydraulic pressure twists the blades in one direction and when removed, the weights twist the blades in the other direction. Some props use a large spring in the dome to accomplish the same thing. Bob Moore ATP CFI

Kind regards, Herman I guess it is a constant speed prop, weights to auto-control the blade pitch when power setting is altered. The AT-6 has a similar setup.
