Numerical Analysis of Intercooled and Recuperated Turbofan Engine

In the last decades the main efforts of aero engine designers have been focused on the possibility to increase maximum attainable thrust while reducing specific fuel consumption. As consequence, very high bypass ratio turbofan engines have been developed, ensuring the specific fuel consumption reduction by means of the increased propulsion efficiency. However this way to operate cannot be followed indefinitely, and some new techniques need to be thought. In this work it has been considered the possibility to increase the efficiency of the engine modifying the working thermal cycle. In fact, by means of the development of a numeric thermodynamic code, it has been simulated the thermal behavior of a turbofan engine in which the practices of intercooling and regeneration are introduced.
