Artist's impression of Boeing-Vertol USAF Air Rescue Squadron Advanced Rescue Aircraft circa 1969.

Rotors are driven by gas turbines in wing tip nacelles. When in forward flight, the rotors fold into the nacelles and propulsion is provided by the engines which will act as turbofans. Designs circa 1969.
