I'm honored to find myself quoted in several places as the "usual source", although my name doesn't seem to appear anywhere... aww

I wish to say that the "AV ..." numbers next to a couple of models point to an old reference system I once used and indicate French aviation weekly AViation Magazine.

No specific designations given, but there were a few civil proposals of the Airgeep.

See Commander31's avatar pic for an example. wink

According to Hesham...

"PA.101 was the Piasecki (PiAC) designation for sales and
manufacturing rights to the Agusta A.101G transport
helicopter in USA."

Hi,

PA-22 was ring-wing concept.
PA-159B was V/STOL vehicle.

Some good stuff here, Hanneton, but you are mixing up Piasecki's two separate numbering systems.

Also, the prototype HRP "Dogship" was not designated XHRP-1 but XHRP-X, a totally non-standard designation.

OK I made an edit where XHRP-X can fit into the system. From all of the sources I have read, there were three HRP prototypes: The first one factory designated PV-3 (which must have been XHRP-X in the military system since the other ones had a "1" instead of "X"), the second for US Navy flight trials (as XHRP-1) and the third for flight testing (as XHRP-1SDTA). Confusing, but I think I get it now!

But I am really hopeless wth the rest of Piasecki's designations. Can you point out the ones I've messed up please?
