Description du projet
Une nouvelle technologie d’échange thermique pour alléger la charge des gros avions
Un avion se compose du fuselage, son ossature principale, des ailes, de la queue, des moteurs et des autres parties. La nacelle est la couverture lisse qui abrite le moteur à réaction. Cette coque aérodynamique minimise la traînée, réduit le bruit et remplit une fonction de dégivrage. Depuis les années 1970, les matières composites des nacelles ont permis de diminuer le poids, le bruit et les émissions du moteur. Pour devenir plus vert que vert, BISANCE propose un système autonome biphasé pour simultanément refroidir l’huile moteur et assurer la protection contre le givre. La chaleur de l’huile du moteur est utilisée pour dégivrer la nacelle. Mieux encore, le nouveau système réduira considérablement le poids, les émissions de CO2 et les coûts d’exploitation des aéronefs à turbopropulseur.
Objectif
BISANCE intends at defining a biphasic system integrated into a full composite nacelle and engine air intake. The biphasic system aims at decreasing significantly the weight, the environmatal footprint as well as the space allocated by the current active systems for the cooling of the engine oil and for the energy supply of th ice protection systems. These both active systems (needing external power) will be replaced by a biphasic passive system (autonomous with no need of external power) which will extract the energy from the engine oil and transfer it to the ice protected surfaces.
The objective of the project is thus to decrease the weight by 25kg for the two nacelles of a turboprop A/C, to decrease the CO2 emissions by almost 900 000 kg per AC life and to save 200 000$ of operating costs per AC life.
The project will be divided into 5 workpackages along 30 months. The first step intends at defining the specifications and the requirements of the product. Based on the requirements, several concepts of system integration into the structure will be proposed and manufactured for selecting the most promising one. Qualification tests are expected for characterizing the structural resistance and stifness of the concept, for verifying the resistance to heat cycles and to impacts. Finally a fulls scale demonstrator will be manufactured for testing it in icing Wind tunnel.
The project will be coordinated by Sonaca, also in charge of the structural developments, in association with Calyos, in charge of the system developments and with RTA in charge of performing the icing wind tunnel testing.
