Efficient Modeling of Hybrid-Electric Aircraft for Design and Performance Optimization Studies

The world is faced with two concurrent trends. The first is the growing demand for air travel in the long term. The second is the need to cut aircraft emissions due to environmental goals and ambitions set by authorities. Fully-electric aircraft are currently infeasible due to the limited battery specific energy and power. Hybrid-electric...

Finding the Operating Limits and Optimal Configuration of an Electrically Assisted Turbofan

Hybrid electric propulsion is a promising new technology to reduce emissions and fuel consumption of an aircraft. In this study a parallel hybrid electric configuration is considered. Since electric motors supply power in the most demanding take-off and climb phases to achieve the required thrust, the turbofan can be redesigned.<br/><br/>It was...
