A counter-rotating 2 cycle piston engine with a combustion chamber and an output shaft rotatably mounted to rotate independently about the same propeller centerline of an aircraft. The Internal combustion power is transmitted to the output shaft by means of a conventional piston, rod, crankshaft configuration journaled to the combustion chamber or engine block in the traditional manner thereby producing concurrent rotation of the shaft and counter-rotation of the engine block. Interior surfaces of the combustion chamber and pistons are angled to control the oil flow inside the crankcase and eliminate unwanted ponding. The pistons are modified to transfer fluid accumulations to the combustion chamber. A throttle is located at the axis of rotation to function normally without the effects of centrifical force. Dual propellers mounted on the shaft and on the block improve thrust performance, balance the torques and moments of inertia of the two counter-rotating masses, All rotational output torque automatically balances itself between counter rotating propellers and is converted into propulsion. No rotational torque is allowed to be transmitted to the airframe through the counter-rotating engine mount.

I claim: 1. An engine with counter-rotating housing and output shaft, comprising the following combination of components: a) A 2 cycle engine block rotatably mounted to allow rotation around the crankshaft center axis, b) Two or more, simultaneously firing, cylinders radially attached to a cooperating crankcase, equally spaced around the cooperating crankshaft, each cylinder aligned to a cooperating off-set journal on the crankshaft c) a crankshaft, journaled at either end to the block, concentric with the central axis, including two or more off-set bearing surfaces, contained within the crankcase, wherein each off-set cooperatingly aligns to a corresponding cylinder d) Two or more connecting rods each journaled at one end to a crankshaft off-set surface and journaled at the other end to the crankcase side of an individual piston e) Two or more pistons each slidably received within a corresponding cylinder f) each combustion chamber arrangement including a spark plug located within the combustion chamber at full compression but not at an outer most cavity subject to centrifical force fluid ponding during crankcase rotation g) a crankcase volume which expands and contracts during operation either systematically intaking through a carburetor or similar device a measured amount of fuel/air/oil mixture into the crank case, or systematically transferring a measured amount of the same fuel/air/oil mixture to the combustion chamber through a cavity in the cylinder wall which allows the fuel/air/oil volume to bypass the piston compression rings (h) means for producing said concentric rotation and counter-rotation as a result of a process of energy conversion; whereby during operation of the engine an inertial balance is established between said output shaft and said housing by rotating in opposite directions concentrically with respect to said engine center line. 2. The engine of claim 1, wherein the crankcase side of the reciprocating piston(s) are tapered toward a transfer port through the side of the piston wall, in alignment to the intake duct, at the centrifugal extremity of those piston surfaces, wherein the piston port aligns with the piston by-pass intake duct to allow for the centrifugal transfer of accumulating fluids through the piston port and bypass duct leading to the combustion chamber for subsequent burning and eventual exhaust from the engine. 3. The engine of claim 1, wherein the inside surfaces of the crank case subject to centrifical fluid ponding are either tapered surfaces to allow for unrestricted flow to the extreme volumes of the crankcase being the crankcase side of the pistons for systematic transfer to the combustion chamber, or are minimally cavitated surfaces to specifically pond enough fluids to lubricate bearings and journaled surfaces of non-reciprocating components without causing an imbalance of the crankcase due to ponded fluid weight. 4. The engine of claim 1, further including inside crankcase minor ridges at non-reciprocating journaled surfaces open to the central axis, which allows for specific centrifical force ponding of a small amounts lubricating fluid, present in the fuel/air/oil mixture, to be trapped at the non-reciprocating bearing points within the crank case and which allows for the sheet flow of oils to pass through but not pond at the bearing surfaces within the crank case which do reciprocate. 5. The engine of claim 1, wherein said engine is a 2 cycle-piston engine and said process of energy conversion includes combustion of a fuel in a combustion chamber; and wherein the engine further includes lubrication surfaces which allows for the sheet flow of oils to pass through but not pond at the bearing surfaces between components which do reciprocate. 6. An engine of claim 1 including a throttle mechanism located at the center of rotation, operated by a typical hydraulic master/slave cylinder connection which allows carburation to occur normally, unaffected by the centrifical forces of its own rotation. 7. An engine of claim 1 including a plurality of cooperating pairs of cylinders fueled by a single carburetor. 8. The engine of claim 1, wherein during normal engine operation, fluids transfer from crankcase to combustion chamber under centrifugal force. 9. The engine of claim 1, wherein during normal engine operation, fluids transfer from intake manifold to crankcase under centrifugal force. 10. The engine of claim 1, wherein crankcase fluids are centrifugally trapped at non-reciprocating bearing surfaces for lubrication purposes but in insufficient quantities to cause engine imbalance. 11. The engine of claim 1 wherein engine cooling is achieved by forcefully rotating engine block through otherwise still ambient air. 12. The engine of claim 1, wherein angle mounted exterior cooling fins are integral to the engine block, wherein during engine/crankshaft counter-rotation, air for cooling is to continuously drawn across cooling fins by both block toward fresh ambient air. 13. The engine of claim 1, wherein crankshaft mounted propeller air rotation speed reductions are automatically achieved by engine block counter-rotation while maintaining crankshaft/block engine operating speeds. 14. The engine of claim 1, wherein engine block and or engine crankshaft rotation speed can be adjusted by changing the dynamic load, geometry or mass of either, or both, rotating components. 15. The engine of claim 1, wherein inside crankcase surfaces are either 1) distally pitched toward the cylinders or toward cooperating adjacent surfaces located farther away from the engine axis of rotation whose surfaces are similarly pitched toward the cylinders or toward cooperating distally pitched surfaces ultimately leading to the cylinders, or 2) contoured to centrifugally trap minor amounts of fluid accumulations at non-reciprocating bearing surfaces. 16. The engine of claim 1, one or more distally pitched interior crankcase surfaces are located tangent to reciprocating bearing surfaces to promote bearing lubrication by centrifugal force driven surface flows of crankcase fluids. 17. The engine of claim 1, wherein a carburetor intake port is located concentric to the engine center of rotation and wherein carburetor moving parts such as the throttle are concentrically balanced about the center axis to operate along the center axis unaffected by centrifugal force.
