Balancing act

[Big John]

11/24/03 AW&ST

Lord Corp and Hamilton Sundstrand are teaming to offer the In-Flight
Propeller Balancing system that automatically adjusts propeller
balance while the aircraft is flying. The installation features one
balancing device for each propeller and one electronic controller,
which accepts accelerometer inputs from the rotating propeller to
constantly adjust the position of weights to minimize an unbalanced
condition.

Nothing new per se.... the idea and general mechanisms have been around
since 1920's..if not earlier.
And I'd be very surprised if there hasn't been some electrical models since
then.
