Aircraft engine rear mount with thrust links and boomerang-shaped lever
View Patent ↗A turbine engine mount to a pylon of an aircraft includes a bracket arranged to be attached to the pylon, and a lever attached in its central part to the bracket via a first connection and two thrust links each joined aft to the lever by a second connection. The lever includes a central part with two arms, and the bracket includes an integral attachment lug placed between the two arms and connected to the arms via a pivot pin to form the first connection. The lever is laterally connected to the bracket via pivot pins passing through the lever and mounted with a clearance to form connections on standby.
1. A turbine engine mount to a pylon of an aircraft comprising:
a bracket arranged to be attached to the pylon,
a lever attached in its central part to the bracket via first connection means with a pivot pin and two thrust links each joined aft to the lever by second connection means and forwardly comprising means for attachment to the engine,
wherein said lever includes a central part with two parallel arms, and said bracket includes an integral attachment lug, the attachment lug being placed between said two parallel arms and connected to said parallel arms via said pivot pin to form said first connection means, and said lever is laterally connected to the bracket via pivot pins passing through said lever and mounted with a clearance to form third side connection means on standby.
2. A mount as in claim 1 , wherein said lever, on either side of the first connection means, comprises a side lug to support forwardly said second connection means with the thrust link and aft said third connection means on standby with the bracket.
3. A mount as in claim 2 , wherein an aft end of each thrust link comprises a clevis cooperating with one of the side lugs via a pivot pin to form the second connection means.
4. A mount as in claim 2 , wherein said bracket comprises a lateral clevis cooperating with one of the side lugs of the lever via one of said pivot pins mounted with said clearance to form the third connection means.
5. A mount as in claim 1 , wherein said lever, on either side of said first connection means, comprises a lateral clevis to support forwardly said second connection means with the thrust link, and aft said third connection means on standby with the bracket.
6. A mount as in claim 5 , wherein an aft end of each thrust link comprises an attachment lug cooperating with one of the lateral clevis of the lever via a pivot pin to form the second connection means.
7. A mount as in claim 5 , wherein said bracket comprises a side attachment lug cooperating with one of the lateral clevis of the lever via one of said pivot pins mounted with said clearance to form the third connection means.
8. A turbine engine mount to a pylon of an aircraft comprising:
a bracket configured to be attached to the pylon;
a lever coupled to the bracket via a central pivot pin and two thrust links each joined aft to the lever;
wherein said lever includes a central part with two arms, and said bracket includes an integral attachment lug, the attachment lug being between said two arms and connected to said arms via said central pivot pin, and said lever is connected to the bracket via two lateral pivot pins passing through said lever and mounted with a clearance to provide two standby connections.
9. A mount as in claim 8 , wherein said lever, on either side of the central pivot pin, comprises a side lug joined to one of said thrust links and joined to one of said standby connections.
10. A mount as in claim 8 , wherein said lever, on either side of said central pivot point, comprises a lateral clevis joined to one of said thrust links and joined to one of said standby connections.
11. A turbine engine mount to a pylon of an aircraft comprising:
a bracket arranged to be attached to the pylon,
a lever attached in its central part to the bracket via first connection means with a pivot pin and two thrust links each joined aft to the lever by second connection means and forwardly comprising means for attachment to the engine,
wherein the first connection means includes two parallel arms spaced apart on the central part of the lever, cooperating with an attachment lug integral with the bracket via the pivot pin, and the lever comprises two third side connection means on standby with the bracket,
wherein said lever, on either side of said first connection means, comprises a lateral clevis to support forwardly said second connection means with the thrust link, and aft said third connection means on standby with the bracket, and
wherein an aft end of each thrust link comprises an attachment lug cooperating with one of the lateral clevis of the lever via a pivot pin to form the second connection means.
12. A mount as in claim 11 , wherein said bracket comprises a side attachment lug cooperating with one of the lateral clevis of the lever via one of said pivot pins mounted with said clearance to form the third connection means.
13. A mount as in claim 11 , wherein said two parallel arms are integral with the lever.
