Mounting assembly for securing an engine to an aircraft wing
View Patent ↗An engine assembly including an engine mount, the engine mount including a rigid structure including a box and a mounting system positioned between the engine and the rigid structure. This mounting system includes an aft attachment. The assembly further includes a thermal protection system for the box, including a preferably ventilated duct forming a heat barrier and extending between the box and the engine. The duct extends rearward beyond the aft engine attachment.
1. An aircraft engine assembly comprising:
an engine;
a mount for the engine, the mount for the engine including a rigid structure including a box and a mounting system positioned between the engine and the rigid structure, the mounting system including an aft engine attachment; and
a thermal protection system for the box including a duct forming a heat barrier and extending between the box and the engine,
wherein the duct extends aftward beyond the aft engine attachment,
wherein said box extends vertically between an upper spar and a lower spar, and said duct is located underneath said lower spar, wherein said rigid structure includes a structural block mounted on the lower spar and connecting said rigid structure to said aft engine attachment, and wherein said duct passes through said structural block.
2. An engine assembly according to claim 1 , wherein the duct is a ventilated duct.
3. An engine assembly according to claim 2 , wherein the ventilated duct includes an aft end leading to an outer wall of an aft pylon fairing of the mount for the engine, the aft pylon fairing being positioned fully aftward relative to the aft engine attachment.
4. An engine assembly according to claim 2 , wherein the ventilated duct includes an aft end leading into inside an aft pylon fairing of the mount for the engine, the aft pylon fairing being positioned fully aftward relative to the aft engine attachment.
5. An engine assembly according to claim 4 , wherein the aft pylon fairing includes an air outlet opening including a controllable, mobile structure which, in relation to its position, can modify an aerodynamic shape of the fairing.
6. An engine assembly according to claim 5 , wherein the mobile structure is placed across the air outlet opening.
7. An engine assembly according to claim 1 , wherein the structural block includes a securing interface for the aft engine attachment.
8. An engine assembly according to claim 1 , wherein the duct is positioned underneath and away from a lower structural element of the box, so as to define jointly therewith a secondary ventilated throughway.
9. An engine assembly according to claim 8 , wherein the secondary ventilated throughway is also delimited laterally by cowls of a nacelle of the engine.
10. An engine assembly according to claim 1 , wherein the duct includes a thermal protection coating.
11. An aircraft comprising at least one engine assembly according to claim 1 .
12. An engine assembly according to claim 1 , wherein said duct is located outside said box.
13. An engine assembly according to claim 1 , wherein said duct has an air intake located underneath the box.
14. An engine assembly according to claim 12 , wherein said box is made of a composite material.
15. An engine assembly according to claim 1 , wherein said box is made of a composite material, and said structural block is made of metal.
