It is therefore necessary to equip these parts with thermal protection means that are compatible with the requirements specific to aircraft engines: durability, direct environmental resistance, low weight, simplicity, proven efficiency, etc.
- thermal protection means are not added parts and instead are integrated parts to protect that already have a specific function in the aircraft engine. It is therefore not possible to use thermal protection sheets, which are effective but which constitute additional parts increasing the mass and decreasing the available space in the engine.
