Information

The boosted turbofan is a key concept in the roadmap to more sustainable aviation, and subject to research worldwide. Limited results have been disclosed for this type of parallel hybrid, and most key aspects resulting from the interplay of electric power and gas turbine subsystems remain proprietary to date. This presentation sheds light on the trade-off between weight and efficiency. After introducing the four established concepts of operation for boosted turbofans, we describe the role of shaft speed and gear ratio as key design parameters. We cover physics-based models to quantify trades, and present typical results.
