1. An internal combustion rotary engine configured to rotate a crankshaft, the internal combustion rotary engine comprising:
a housing configured to receive the crankshaft along a central axis of the housing, the housing including a cold side compartment separated from a hot side compartment along the central axis, the cold side compartment including a cold side inner cylindrical surface having at least one cold side lobe extending therefrom, the hot side compartment including a hot side inner cylindrical surface having at least one hot side lobe extending therefrom;
a cold side planetary gear set having a cold side sun wheel centered about the central axis and at least one cold side planet wheel rotatably coupled to the cold side sun wheel and sealed between the cold side sun wheel and the cold side inner cylindrical surface, the cold side sun wheel including a cold side sun wheel circumference and at least one cold side semicircular opening defined along the cold side sun wheel circumference and configured to at least partially receive the at least one cold side planet wheel, the at least one cold side planet wheel including at least one cold side planet wheel indentation configured to at least partially receive the at least one cold side lobe when the at least one cold side planet wheel rotates along the cold side inner cylindrical surface;
a hot side planetary gear set having a hot side sun wheel centered about the central axis and at least one hot side planet wheel rotatably coupled to the hot side sun wheel and sealed between the hot side sun wheel and the hot side inner cylindrical surface, the hot side sun wheel including a hot side sun wheel circumference and at least one hot side semicircular opening defined along the hot side sun wheel circumference and configured to at least partially receive the at least one hot side planet wheel, the at least one hot side planet wheel including at least one hot side planet wheel indentation configured to at least partially receive the at least one hot side lobe when the at least one hot side planet wheel rotates along the hot side inner cylindrical surface;
an air compression chamber defined between the at least one cold side planet wheel and a cold side leading edge portion of the at least one cold side lobe as the at least one cold side planet wheel approaches the at least one cold side lobe when rotating along the cold side inner cylindrical surface;
a combustion chamber defined between the at least one hot side planet wheel and a hot side trailing edge portion of the at least one hot side lobe as the at least one hot side planet wheel departs from the at least one hot side lobe when rotating along the hot side inner cylindrical surface; and
at least one compression passageway defined between the cold side inner cylindrical surface proximate to the cold side leading edge portion of the at least one cold side lobe and the hot side inner cylindrical surface proximate to the hot side trailing edge portion of the at least one hot side lobe.
