A rotary engine including a drive element rotatably disposed within an open interior of a drive chamber, the drive chamber having an interior wall structure which defines the open interior including a fuel intake region, a combustion region, an exhaust region, and a fluid intake region therein. The engine further includes a plurality of combustion chambers disposed about a periphery of the drive element and movable with the drive element relative to the drive chamber. Further, the combustion chambers are sized in accordance with a relative spacing between the drive element and the interior wall structure, the interior wall structure being defined so that the combustion chambers decrease in size as they rotate through the fuel intake region, thereby compressing a fuel contained in the combustion chambers, increase in size as they rotate through the combustion region, thereby facilitating maximum expansion of combusted fuel in the combustion chambers, decrease in size as they rotate through the exhaust region, thereby maximizing an evacuation of exhaust fluids from the combustion chambers, and increase in size as they rotate through the fluid intake region, thereby maximum an intake of fluid into the combustion chambers. A plurality of fin elements are provided to variably extend from the drive element in accordance with the contour of the interior wall structure and define substantially fluid impervious leading and trailing ends of each combustion chamber.
