Yes, this is the XH-17, built by Hughes, in Culver City. It was originally
designed by Kellet, and the project was killed in 1953. This didn't use
ramjets, but it was powered by the two big J-35 jet engines, pumping hot air
through the rotors. Not to be confused with their later hot air cycle
helicopter, I think, the XV-9A. I don't believe Hiller ever made their
heavy lift coptor concept, but they made the small two man Hiller Hornet,
YH-32. Mcdonnel also made a small two seat ramjet powered rotor, called the
XH-20, but, I think those are the only two to fly.

Ron, the photo of the model I posted isn't the XH-17. It's in the Hiller
Aviation Museum in San Carlos, CA. It's the same model in the photo that
Troy posted. Here's all three to compare.
