An engine having a main power turbine operating on the Brayton cycle, has its air supply furnished by a compressor independently driven by a Rankine turine which derives its heat energy from the exhaust of the Brayton turbine. The engine is constructed in modules. One module consists primarily of a single stage Brayton turbine, with an output gearing system, and a coaxial extension containing an intercycle heat exchanger. A second module comprises a single stage Rankine turbine and a single stage compressor driven thereby for supplying air to the Brayton turbine, a feed pump for the Rankine fluid interposed between the Rankine turbine and the compressor, and accessory devices driven by the Rankine turbine for starting the engine. The second module has its axis perpendicular to the axis of the first-mentioned module. A condenser-regenerator module is disposed in a plane perpendicular to the axis of the second module and parallel to the axis of the first-mentioned module. A burner and air supply unit extends between the first and second modules generally parallel to the condenser-regenerator module.
