New Addition: Ducted Fan Rotors

Before commercial ducted fans became available, Lt. Col. Wallace “Mike” Kulczyk built his own ducted fan units for his scratch-built jet aircraft.   Several of the rotors for these units were recently donated to the museum’s collection by Richard Maus, In Memory of Lt. Col. Wallace “Mike” Kulczyk.

3 wooden ducted fan rotors and one metal ducted fan rotor.  A wooden flow straightener is at center.
Four of the ducted fan rotors and one flow straighener made by Lt. Col. Wallace “Mike” Kulczyk.

Thanks, Dick, for helping to grow the museum’s collection!
