I was thinking if you had a disc like a pressure plate mounted on the prop area of say a Mac engine. Instead of the drum used on the Wunderlich.
If this Disc was say 12 inches in Dia. Now if you run the pre rotator wheel against the disc closer to the center it would turn at speed "a"... now if you were to move the wheel outward it would have to turn faster now at speed "b".. Move it all the way out and it would be much faster.. now as speed "C"..
Does this make sense or am I just somewhere out there in never never land?
It looks to me like it would work.. you could run you engine at a set speed and increase the speed of the pre rotator quite a bit to get your blades poping......
