abstract

The gas turbine engine design is fundamentally, taking the air flow into the compressing stage then combustion stage to add energy, and finally extracting energy in the turbine module. This journey of the flow in the engine is in serial connections. Posing the problem of the limiting turbine inlet temperature, the number that all the turbomachinery engineers desperately want to increase by tuning the inlet stages materials, or fine changes onto the blades’ profile or the flow paths. But the significant increase to this temperature lies under more fundamental and radical redesigns to the theory of the gas turbine operation, and its thermodynamical cycle. These principles were considered for long untouchable facts, and stayed lurking from the engineers examining eyes. This paper introduces one of these possibilities by genuine redesign concepts. Backed with CFD analysis, and Thermodynamical feasibility studies to address the potential problems of these modifications. The redesigns include implementing the new concept of the contra-rotating turbine more effectively to reduce the turbine module size, connecting pressurized fluid streams of two counter-rotating compressors in parallel instead of the serial connection, forming a protecting Pressurized shield for the entry turbine stages and, Extracting the energy in the process flow using flows interactions instead of flow-blades interactions.
