Engine mast gasket

The engine pylon joint provides aerodynamic continuity between the wing and the nacelle.
This area is subject to enormous mechanical stress induced by engine thrust. Structural deformations are quite considerable.
Joints therefore have to bridge significant clearances. As the aerodynamic surface needs to be as smooth as possible, seals with a lip on the outside are used.
To limit the risk of flagging on contact with the air flow, the seal should be reinforced with glass fabric.
Particular care must also be taken to protect the leading-edge seal.
Calling on Sealicone during the design validation phases will ensure the best design for the required performance, service life and weight.
