Gas Turbine Engines: Jet Engine Turbofan Solution

Handling High Temperature

Jet Engine Turbofan

The last decade has seen the development of many new turbofan engines. All these engines have been designed to achieve the same goals: reduction in fuel consumption, noise and emissions. This is where our OmniSeal® PTFE seals are valuable.

Different technologies have been used by jet engine manufacturers to reach these goals resulting in a global increase of the working temperature required in the engine. The consequence is significant as the higher working temperature becomes a challenging problem for all mechanical components but more specifically for elastomers and polymers components that in some cases need to be upgraded for better performing materials.

Our OmniSeal® seals are the perfect solution to replace elastomer seals who have reached their limit. The low sensitivity to thermal aging of Fluoroloy® material used to make the jacket on these seals have proven to provide better sealing control and confidence through lifetime of the equipment. This is mainly true for sealing of the lubrication system of the engine where seals are critical components. This is the reason we created a new Fluoroloy® A90 material, which is best suited for the following jet engine applications: bearing chambers, sump system, internal gearboxes and accessories as well as all other applications with high-temperature requirements.

Saint-Gobain Seals has worked with many top aerospace companies to address not only higher working temperature but also improve the configuration of the turbofan itself.

Our dynamic and static sealing components were specified for use in a new series of geared jet engines. In recent times, with the need to make flying more efficient, the geared engines have emerged as an alternative design and technology to conventional turbofans for a thrust range from 10,000 lbs to 40,000 lbs.
