Modeling and Characteristics of a Novel Multi-fuel Hybrid Engine for Future Aircraft

Civil air transportation has undergone significant expansion over the past decades and is continuing to grow. Nevertheless, the tendency of energy depletion and the severe environmental problems yield challenges in its further development. To mitigate the climate impact of civil aviation, the Advisory Council for Aeronautics Research in Europe ...

Design of a cooling system for the hybrid engine

In recent times the fuel prices have increased significantly. This implies major reductions in profit margins for airlines. Additionally the increasingly stringent emission standards for aircraft generate the need for better fuel economy. This master thesis aims at providing a contribution to lower the emissions made by future turbofan engines...

Design of a Semi-Empirical Tool for the Evaluation of Turbine Cooling Requirements in a Preliminary Design Stage

There is an everlasting demand for higher cycle efficiencies in gas turbine engines. One way to obtain a higher efficiency is to increase the overall pressure ratio (OPR) of the engine. In order to benefit from the efficiency increase whilst maintaining the same specific gas power, the turbine inlet temperature (TIT) has to increase with it....
