<p>The present invention provides a novel aircraft subsystem that provides both electricity and conditioned air to the aircraft independently of the main engines. The subsystem includes turbomachinery comprising three independently rotating assemblies: a low pressure module including a low pressure, (LP), compressor and a low pressure, (LP), turbine; a high pressure module including a high pressure, (HP), compressor, an HP turbine, a combustor, and a starter motor; and a power module including a power turbine, a load compressor, a shaft mounted generator, and a cooling turbine. An intercooler is provided between the LP and HP compressors. The ram air requirements of the subsystem are substantially reduced over the prior art as a result of the high pressure ratio compression achieved through the two stage compression with intercooling, in conjunction with an optimized design of the engine air, heat exchanger air, and intercooler air ingestion and discharge systems.</p> |
