The engines, and more generally the propulsion system, are a fundamental system for the aircraft, to which they provide the thrust necessary for movement, from the energy source that constitutes the fuel transported. In doing so, they produce noise and emissions that have an impact on the environment, but this impact is not independent of the characteristics of the aircraft itself…
Aircraft and Engines: very close interdependence
The degree of integration of engines in aircraft is extremely high. Depending on increasingly strong requirements, increasingly ambitious objectives, associated with ever more difficult challenges, in an increasingly large field, with complex problems to be solved, the criticality of this integration can only increase.
The performance of aircraft depends on the intrinsic performance of the engines (specific consumption, thrust, noise) and also on the way in which the propulsion systems are installed, in terms of aerodynamics including interactions with…
