    • A power plant for driving a load comprises an internal combustion engine, an exhaust turbine, primary and secondary compressors, and first and second planetary differentials each having an input and two outputs. The first differential has its input driven by the engine output, its first output connected to the load, and its second output driving the secondary compressor. The turbine drives the primary compressor and the second differential, which has its first output connected to the first differential input and its second output connected to the load. The compressor discharges flow in series or in parallel through a heat exchanger to the engine inlet manifold and the engine exhaust drives the turbine. A portion of the net compressor discharge is by-passed around the engine through a heat exchanger to recover heat from the turbine exhaust, and through an afterburner to the exhaust turbine. A speed control device connects the second output of the first differential and the load. The speed control device comprises a variable displacement hydrostatic pump driving a variable displacement hydrostatic motor, and a control for the displacements; it may also comprise an electric generator and motor set with a control for the fields.
