This project is a research towards developing a new, breakthrough, high speed propulsion system technology envisioned to trigger a step change in air transportation in the second half of this century and based on the principle of pulsed detonating combustion. This new, radical approach to create propulsion power aims at reducing the weight, the complexity, and the cost of the classical, air breathing, aero-engine and, thus, at significantly reducing the overall fuel consumption and, consequently, the total amount of pollutants emission. The research efforts are carried out as part of a European research project, funded in by the European Commission within the Framework Programme 7.
