Long live the conceptual creations of Frank Piasecki!
This program appears as though it will extend the reign of his tandem rotor beasties to near or perhaps even beyond the 100 years mark. Piasecki's early contributions in the area of compound helicopter design were also significant. The resurgent compounds now seem to be competing with tilt-rotors for next generation VTOL supremacy. But even as VTOL technology marches ever onward, the venerable Chinook marches with it and remains a versatile workhorse that can't cost-effectively be replaced.
