Abradable Seals - for Compact Turbine Engines

In today's competitive aerospace and turbine industries, efficiency and reliability are paramount. As technology advances, the need for precision-engineered solutions that address complex challenges has never been greater. Technetics, a leader in innovative sealing solutions, introduces its FELTMETAL™ Abradable Seals, designed to meet these demands head-on. These seals offer an alternative approach to reducing turbine blade-to-shroud gaps, maximizing performance and durability even in the most extreme conditions.

Technetics has created a method to handle all challenges head-on. The FELTMETAL™ Abradable Seals decrease the gap between the turbine blade and shroud, ensuring maximumefficiency and dependability.

These seals are comprised of a fiberized metal structure sintered to a certain density, usually between 18% and 40% of a solid alloy. As the turbine expands at higher temperatures, the blade cuts through the abradable material, forming a groove unique to the blade and reducing leakage.

The FELTMETAL™ material is designed to reduce blade damage and prevent debris from polluting downstream systems.

The material's porosity enables minimum airflow to disperse heat. The convoluted path "traps" air within the pores prevents a leakage channel.

Customization

Technetics has decades of experience tailoring FELTMETAL™ Abradable Seals to individual system demands, including development choices to solve unique erosion and abradability concerns.

Installation Advantages

The FELTMETAL™ Abradable Seals are intended for easy installation, expediting the procedure.

Pre-Brazed Options

The seals are available in solid or segmented metal housings and are pre-brazed, ready to be press-fitted, or bolted into position. This removes the need for extra brazing or spraying, which saves time and reduces complexity.

Versatile Integration

The seals can be designed to braze into the current housing materials, ensuring a smooth connection with the engine components.
