ABSTRACT:
Four-wing, non-intermeshing rotors are optimized for synchronous rotation to be driven by synchronous drive means at a constant 180.degree. phase angle, there being two long wings and two short wings on each rotor. A first long wing and first short wing originate at a first end of each rotor, and a second long wing and second short wing originate at the second end of each rotor, the helix angle "A" being the same for all wings on both rotors, and being in the range from about 10.degree. to about 50.degree.. The axial length l.sub.1 is the same for all long wings, the axial length l.sub.2 also being the same for all short wings. Each rotor has a transition zone opening between the termination of a short wing and the termination of the next succeeding long wing relative to the direction of rotation, the next succeeding long wing originating at the opposite end of the rotor from the short wing. Thus, there are two transition zone openings on each rotor, and all four of the transition zone openings are the same; that is: Q.sub.1 =Q.sub.2 =Q.sub.3 =Q.sub.4. The axial and rotational forces are the same for all the long wings. Also, the axial and rotational forces are the same for all the short wings. The axial forces on each rotor advantageously are balanced as well as the rotational and axial forces of both rotors.
