Abstract: A two-spool turbojet built up of major bladed components first developped for unrelated turbofan engine types. The high pressure (“HP”) spool comes from a turbofan which powered a large airliner carrying 300 or more passengers across a continent or an ocean. The low pressure (“LP”) compressor is the fan from a military aircraft's engine or a smaller airliner turbofan, or both. The object is that all the LP compressor output goes into the HP compressor, making a turbojet from existing turbofan components. This saves development costs, and creates an engine for propelling a large aircraft at supersonic speeds more efficiently than by an afterburning turbofan. In the preferred embodiment, the number of stages in the HP spool is halved, saving weight for the addition of a remote fan (known elsewhere) which doubles the air mass flow. That increases propulsive efficiency during subsonic cruise.

Abstract: Unique engines, air compressors, and pneumatically driven electrical generators are disclosed. The engine employs a rotor having a number of pistons slidably disposed within respective cylinder bores extending into the rotor periphery. As the rotor spins within a stator, each cylinder bore passes a combustion stage at which the piston is driven further into the rotor toward a bottom of the respective cylinder bore.

The unit thus operates as a self driven compressor, or engine-compressor combination, and the compressed air may be used to pneumatically drive a turbine of an electrical generator. A carbon splitter dissociates carbon and oxygen molecules from the carbon dioxide in the air downstream of the generator turbine, reducing the overall carbon dioxide output of the system.
