Hi folks,
today while flicking through magazines at a bookshop near my local train station, I saw a picture of the Boeing Model 222 tilt rotor aircraft featured in an article about the "X-series Aircrafts (Part 19): AD-1 and XV-15" published in the German magazine "Fliegerrevue" Issue 02/08.
At home I found the same picture in a NASA document about the XV-15.

Source (PDF): http://history.nasa.gov/monograph17.pdf (31.01.2008)Boeing provided a proposal based on the new Model 222. This design used the
Boeing-developed 26-foot diameter soft-in-plane hingeless proprotor on nacelles
that tilted only the proprotors. The engines of the 222 were mounted in fixed
horizontal wing-tip nacelles. To minimize research aircraft development costs,
the Boeing 222 was to use the fuselage, landing gear, and empennage of the
Mitsubishi Mu-2J twin turboprop executive transport aircraft. The 222 wing
incorporated leading edge “umbrella” flaps and large deflection trailing edge
flaps to reduce download. An artist’s illustration of the Boeing 222 in flight is
shown in figure 35.
