Abstract
Civil aviation is driven nowadays by exceptional growth in the number of passengers. It should double or even triple by 2050 and thus, all industrials also plan to double the number of device delivery by mid-century. Responsible for about 2% of carbon dioxide on the planet, they must now deal with the environmental issues facing the sector. At this moment in the world, several lines of research focus on increasing the efficiency of aircraft engines, development of new engines, efficient technologies, sustainable sources of alternative fuels and improved management air traffic on the ground and in flight [1]. The present work deals with a research focused on the engine test when passing in review in repair facilities. This operation which consist in making engine running while the cycles to test its performance in a test bench are studied to define a technological solution to reduce CO2 carbon footprint of the aircraft engine in this phase of the cycle of life. The idea is to produce electrical energy during these tests. To achieve this, we will highlight the case of a type bench facility for a specific airplane engines. As a result high-performance analysis tools are implemented to define the most suitable technological solution that ensures maximum efficiency, meets the functional and regulatory requirements taking into account the force of integration with the existing and cost optimization. In this paper we present the summary of the working definition of the research process for the final term set in the operating environment integration relevance that provides bench test and level of innovation that provides the methods selected.
Highlights
Air traffic grew strongly, to support the growth of orders; the performance, the economic and the environmental issues are first rate for all aircraft manufacturers
We are going to present the results of calculation for the case of the bench test without obstacle of the cylindrical grate in extension of the tunnel of the bench test exhaust; the complementary study for the case with the grate noise reducing, this is to identify the potential of energy recovery in both configurations
We notice that the airflow inside the bench test presents much turbulence, which is for the admission or for the exhaust
Summary
To support the growth of orders; the performance, the economic and the environmental issues are first rate for all aircraft manufacturers. They are increasingly involved in the battle against climate change through direct action off the main causal link consumption of fossil fuels, it is the vision that the manufacturers, carriers and airports show up. We are required to follow a study approach; this must include the complexity of the topic and the major elements that fit into its constitution. The aim is to define the energy potential of the bench in order to open the axis towards a improvement or breaking innovation for possible technological solution
