AI Technical Summary

Technical Problem

Flexible spring clamp seals are prone to deformation and vibration in gas turbine combustion chambers due to insufficient rigidity, leading to seal failure and affecting the temperature and safety of combustion chamber components.

Method used

A gas turbine combustion chamber sealing structure is designed, which adopts a concentric fit between the inner and outer rings of the sealing element, with gaps evenly distributed on the inner and outer rings. The gaps are overlapping and staggered in multiples. The gaps on the outer ring are non-through gaps, while the gaps on the inner ring are partially through gaps. They are connected by welding holes to enhance the rigidity of the sealing element.

Benefits of technology

Increase the rigidity of the seals, reduce vibration and deformation, extend the life of the seals, reduce the risk in high-temperature areas, and ensure the effectiveness of the cooling airflow channels.
