Your Sunday Motor Rotor Noise

Kaman HH-43:

If you believe the FAA's registry, six are in private hands.

Had not realized it was an Anton Flettner design, who was swept up by Operation Paperclip after WWII and renditioned to the US like so many others to help the US with jets, swept wings and all things nazi and zoomy (the USSR stole German
engineers for the same purpose). Flettner designed the very early successful 'Hummingbird' nazi helicopter. I think every major usaf base in Vietnam used these for s&r and fire suppression. Per Wikipedia it accrued twice the operational hours of all other rescue types combined, though newsreels of the day always show hueys or navy type winching downed crewmen through jungle canopy. Maybe the Kamens lacked range for distant rescues. The piston engine was replaced first by a turbine and then by two- a 1st for helicopters.

Intermeshing rotors are "more efficient" as far as lift goes, but that type of helicopter is always in "granny" gear.

Check out its sort-of descendant, the Kaman K-1200 K-MAX. An un-manned version moved over 1,500 tons in Afghanistan. But its never exceed speed is 100 kn clean and 80 kn with a slung load
