COMBINED NUCLEAR BOOST AIRCRAFT ENGINE Russian patent published in 2010 - IPC F02C1/05 

FIELD: engines and pumps.

SUBSTANCE: combined nuclear boost aircraft engine includes gas turbine engine with compressor, and combustion chamber to which there connected is fuel pipeline from fuel pump, turbine and jet nozzle. After turbine, on engine shaft there installed is Stirling engine which includes at least one operating cylinder installed downstream the turbine, and at least one expansion cylinder installed downstream operating cylinder. Each expansion cylinder has a casing forming together with that cylinder a cooling cavity. Cooling cavity inlet is connected to outlet of air supply connection pipe the inlet whereof is connected to compressor cavity. Cooling cavity outlet is connected to cavity inside jet nozzle. In the second circuit there installed is cooling heat exchanger. Before Stirling engine and in the second circuit after cooling heat exchanger there installed are heating heat exchangers connected to nuclear reactor. All the expansion cylinders are installed partially or completely inside jet nozzle shield.

EFFECT: increasing efficiency of aircraft engine at decrease of its weight, cost and improvement of reliability.
