P.V. Engineering and Piasecki Projects & Prototypes

[JohnR]

The front fuselage looks like an attack helicopter, rather than the X49. It suggests to me the fuselage of the S67 Blackhawk but with a four bladed rotor! I know there was only one Blackhawk built, was there a mock up built as well?

I assume it's a mock-up of this:

Piasecki's greatest challenge is that they elected to remain an experimental rotorcraft research organization, and thus do not have the capability to produce a product beyond a prototype. The legal, contractual, engineering, and governmental unknowns make it improbable that any production capable OEM would be willing to agree to fund full development of a third party design. This is unfortunate as Piasecki is certainly capable of designing a functional rotorcraft.

From this Russian book,

they were a generic concepts,but I think that design was for Piasecki or based on it,the others maybe
for Gyrodyne and Bell ?.
