1. A bilateral rotary combustion engine for providing torque, said engine comprising:
a planar housing having a circular center cavity, and first and second circular lateral cavities overlapping said center cavity and disposed along a longitudinal axis;
a truncated ellipsoid rotor that turns on a rotor shaft along a rotation axis perpendicular to said longitudinal axis, said rotor being disposed within said center cavity;
a pair of double-concave blades that flank said rotor disposed within their corresponding lateral cavity and turn on corresponding blade shafts parallel to said rotor shaft;
fore and aft cover plates that flank said housing along said rotation axis to cover said center and lateral cavities; and
a gear box disposed on said aft cover plate and having a rotor gear wheel and adjacent corresponding blade gear wheels, said rotor gear wheel turning with said rotor shaft while engaging both blade gear wheels along their peripheries, said blade gear wheels turning with said corresponding blade shafts, wherein said blades turn opposite to said rotor, and
a first portion of said first lateral cavity periodically joining a second portion of said center cavity to provide first intake, first compression, first power and first exhaust strokes, while a third portion of said second lateral cavity periodically joining a fourth portion of said center cavity to provide second power, second exhaust, second intake and second compression strokes as said rotor and said blades turn.
