Re: Hughes high-speed compound helicopter of 1982

Apologies for the thread zombification, but I'm guessing the "compound helicopter" in hesham's first image uses the hot cycle tech? The blades don't look to have the XV-9A-type tip diffusers, but I see no tail rotor either?

Daulphin.

Hi hesham - is that under the horizontal stabiliser? It's hard to make out.

Is this a Hughes high-speed compound helicopter concept for 1982?

I change the title to be 1966.
