Internal combustion engine with rotating pistons and cylinders and related devices and methods of using the same

A rotary engine, comprising:

• a. a piston rotor having a plurality of pistons thereon and positioned on a first rotational axis;
• and
• b. a cylinder rotor having a plurality of cylinders thereon and positioned on a second rotational axis, wherein the first rotational axis and the second rotational axis are oblique relative to one another, and each of said plurality of pistons is nested in one of said plurality of cylinders and the rotation of said piston rotor and said cylinder rotor is driven by combustion of a fuel in said cylinders.

A mechanical apparatus, comprising:

• a. a piston rotor having a plurality of pistons thereon and positioned on a first rotational axis;
• and
• b. a cylinder rotor having a plurality of cylinders thereon and positioned on a second rotational axis, wherein the first rotational axis and the second rotational axis are oblique relative to one another, and each of said plurality of pistons is nested in one of said plurality of cylinders.

A method of generating propulsive force, comprising:

• a. positioning a plurality of pistons connected to a piston rotor positioned on a first rotational axis in a plurality of cylinders positioned on a cylinder rotor positioned on a second rotational axis to form a plurality of paired pistons and cylinders, wherein the first rotational axis and the second rotational axis are oblique relative to one another;
• and
• b. combusting a fuel in said paired pistons and cylinders in a sequential pattern to drive rotation of said piston rotor and said cylinder rotor, wherein said rotation of one of said piston rotor and said cylinder rotor drives rotation of a power shaft for transmitting rotational motion from one of the piston rotor and cylinder rotor to a transmission system for providing mechanical power to another system.

A method of fluid movement, comprising:

• a. positioning a plurality of pistons connected to a piston rotor positioned on a first rotational axis in a plurality of cylinders positioned on a cylinder rotor positioned on a second rotational axis to form a plurality of paired pistons and cylinders, wherein the first rotational axis and the second rotational axis are oblique relative to one another;
• and
• b. moving a fluid through said paired pistons and cylinders in a sequential pattern, wherein said rotation of one of said piston rotor and said cylinder rotor results in movement of said fluid from said cylinders into an exhaust system.
