Engine nacelle seals

Nacelle and engine seals are located in a very specific environment on the aircraft.
It's a hot, pressurized environment, with the risk of fire.
There are 2 types of nacelle seals: reverser door seals and nacelle peripheral seals.
Nacelle door gaskets have conventional requirements, and are usually hollow, with reinforcements giving them a low coefficient of friction to withstand the friction to which they are subjected each time the reverser doors are opened.
Nacelle peripheral seals, like engine seals, must be fireproof. They are also known as "fireproof seals".
These complex seals are made of materials specifically developed for use in hot environments, and are fire-tested in accordance with ISO2685 and AC20-135.
These seals can only be developed jointly. Our design office, experienced in collaborative work, combined with our production know-how, will enable us to develop your nacelle and engine seals efficiently.
Our strategy of capitalizing on experience, in which we involve our customers, enables us to adopt a continuous improvement approach to our products.

Details

The nacelle is a structural element that surrounds the engine.
Nacelles are made up of a number of moving parts, some of which operate on a flight-by-flight basis (thrust reversers) and others for maintenance purposes.
In particular, nacelles have to contain a fire if an incident occurs in the engines, so the joints have to withstand very severe aggression.
Nacelle seals are fireproof seals. What's more, during operation, the internal pressure level is high.
As a result, nacelle seals are complex gaskets made of materials specifically developed for use in hot environments, and fire-tested in accordance with ISO2685 and AC20-135.
These seals can only be developed jointly. Our design office, experienced in collaborative work, combined with our production know-how, will enable us to develop your nacelle seals efficiently.
