Pitcarin PA-39 Revisited

[okikuma]

After revisiting photos of the 1941 Pitcairn PA-39 Autogiro - N3908 at the EAA museum it is to my understanding that Picarin purchased back all the remaining PA-19s (minus one PA-19) and rebuilt the airframes into PA-39s for sale to the RAF. The new PA-39s were then loaded onto a ship bound for England. Unfortunately, the ship was sunk by a U-Boat. The Picarin company kept one for further testing (N3908). It is interesting the autogyro had a "Control Yoke" instead of a cyclic control stick.

The rotor head is complex and interesting... I enclose another photograph found in the internet. The small cylinders may house hydraulic pistons for the pitch change takeoff/cruise...

I see no lead-lag dampers, unless that's the job of the rods in the picture...

You can Adjust the phasing on those but there does not appear to be any rubber or mechanical damper mechanism.
