NUCLEAR GAS TURBINE AIRCRAFT ENGINE Russian patent published in 2010 - IPC F02C1/05 

FIELD: engines and pumps.

SUBSTANCE: proposed engine comprises first and second stages, outer and inner shafts with fan fitted on inner shaft and compressor fitted on outer shaft, and at least one turbine working wheel fitted on outer shaft. It comprises also combustion chamber arranged between compressor and turbine, air intake, turbine and jet nozzle with central fairing. Stirling engine is arranged behind the turbine in central fairing of jet nozzle, coupled with inner shaft and communicated, via heat carrier lines, with nuclear reactor, while, via air channel between said shafts, it communicates with chamber arranged downstream of the fan. Heat exchangers communicating with nuclear reactor are arranged ahead of combustion chamber and in second stage. Stirling engine consists of two sets of working and expansion cylinders. Note here that working cylinders are installed in second stage, while expansion cylinders seat in second stage.

EFFECT: higher efficiency and reliability.
