This paper presents the application of circulation control rotor CCR technology to a revolutionary new aircraft concept--the X-Wing stopped rotor VStol. This design affords the potential for major advances in rotary wing aircraft speed, range-payload, productivity, and cost through the application of highly innovative aerodynamic and structural design. The technology base for the concept has been derived from almost 6 years of related CCR aerodynamic and structural design studies at the David W. Taylor Naval Ship Research and Development Center DTNSRDC and from earlier research in the United Kingdom. Additional design insight has been gained from the experience of various stopped and stowed rotor concepts of the 1960s and also from recent studies of the NASA oblique wing transonic transport concept.
