Project Number: 047 COMPLETE
Category: Aircraft Technology Innovation, Supersonics
This project will develop frameworks for quantifying the noise and emissions footprints of propulsion systems employed on supersonic civil aircraft, integrating models of aircraft performance, engine thermodynamic cycles, and gas turbine combustors. These tools will be used to quantify the performance of a range of engine designs relevant to currently-proposed civil supersonic aircraft and create a roadmap for technology development.
This project is supporting innovation in aircraft technology by providing a detailed technical evaluation of how the use of a clean-sheet engine design could reduce the fuel burn and noise produced by future supersonic aircraft thus enabling continued aviation growth. It is also providing technical data on supersonic aircraft engine design. The analysis will inform decision makers on what is in the realm of the possible with the use of new technologies and accounting for the unique conditions in which supersonic aircraft operate. The work will also demonstrate the limited relevance of information about supersonic aircraft that are no longer in service. This research will show the potential that can be achieved using technological innovations in modern supersonic aircraft.
