Sammanfattning
This report focused on studying and comparing new technologies in aircraft engines
with today’s conventional engines. By exploring research questions that examine
current engine solutions in commercial aviation, assessing the relevance of new engine
variants for further development, and investigating how a functional model of an
aircraft engine can be designed to facilitate teaching, the group has gained a deeper
understanding of aircraft engine performance and environmental sustainability.
The report identifies that turbofan and turboprop engines dominate commercial
aviation today, while the trend continues towards electrification and hybridisation
to reduce environmental impact. New engine variants, such as the Rolls Royce UltraFan
and all-electric engines, show promising benefits in terms of lower emissions
and improved performance compared to older engines. However, challenges remain
to be overcome, particularly in battery technology to enable fully electric aircraft at
longer distances.
The 3D-modelled functional model of a twin spool turbofan and open rotor engine
has been designed to facilitate teaching and demonstrate basic engine functions. The
model fulfills the main requirements and many of the requests in the requirements
specification, but there is room for improvement, especially in weight and number
of configurations.
Finally, with the ongoing development and research in aero engines, there is an
exciting future for the aerospace industry where environmental sustainability and
efficiency continue to be the drivers of innovation.
