Two General Electric YT64-GE-6 turbojets were used as gas generators, the jet efflux was ducted to nozzles at the blade tips.

Re: Hughes XV-9A
The rotor blades also had cooling ducts in both the leading and trailing edges.
To keep costs to a minimum the cockpit with two side-by-side seats of an OH-6A was used and the landing gear was from a Sikorksy H-34.
