Title (EN) DUCTED SPINNER FOR ENGINE COOLING
(FR) CASSEROLE CARENEE DE REFROIDISSEMENT DU REACTEUR
Abstract:
(EN) A system for cooling a ducted fan aircraft engine includes a first nacelle surrounding the engine and a second nacelle substantially concentrically surrounding the first nacelle. The system includes a first spinner coupled around a base of a rotor of the ducted fan and a second spinner substantially concentrically surrounding the first spinner and forming a duct between first and second spinners. The second spinner includes an opening to allow air to flow into the duct. The rotor includes a plurality of airfoils penetrating through the first and second spinners. Each of the airfoils includes a first portion located in the duct, and a second portion located between the second spinner and a fuselage of the ducted fan. The first portions of the airfoils provide cooling airflow over the engine and structural support for the second portions. The second portions of the airfoils provide thrust for the aircraft.
(FR) Selon l'invention, un système servant à refroidir un réacteur d'aéronef à soufflante canalisée comprend une première nacelle entourant le réacteur et une seconde nacelle entourant de manière sensiblement concentrique la première nacelle. Le système comprend une première casserole fixée autour d'une base d'un rotor de la soufflante canalisée et une seconde casserole entourant de manière sensiblement concentrique la première casserole et formant un canal entre les deux casseroles. La seconde casserole présente une ouverture permettant l'écoulement de l'air à l'intérieur du canal. Le rotor comprend une pluralité de surfaces portantes pénétrant la première et la seconde casseroles. Chaque surface portante présente une première partie située dans le canal et une seconde partie située entre la seconde casserole et un fuselage de la soufflante canalisée. Les premières parties des surfaces portantes assurent un écoulement de l'air de refroidissement sur le réacteur et fournissent un support de structure pour les secondes parties. Les secondes parties des surfaces portantes assurent la traction de l'aéronef.
