Royce,
      On the 2 rotor engines, the rotors are cooled by spraying oil inside of
the rotor.  Will there be a similar cooling means for the single rotor and if
so how  will it be done? If it is eliminated, will this compromise the
reliability of the engine?

Thanks.

Wally

Wally the rotor cooling oil spray will still be used.  The jet will be relocated to
the e-shaft between the rear end housing and the rotor. Remember the rotor is being
geared from the front stationary gear.
