AI Technical Summary
Technical Problem
Traditional one-piece forged turbine containment rings are heavy, making it difficult to achieve lightweight design while maintaining containment capacity.
Method used
A separable turbine containment ring with a lattice structure is used. The inner ring, outer ring and lattice containment ring are coaxial. The lattice containment ring is embedded into the outer ring through interference fit and thermal expansion assembly method to form a lightweight structure.
Benefits of technology
It effectively reduces the overall weight of the turbine containment ring while maintaining or improving its containment capacity, and utilizes the energy absorption characteristics of the lattice structure.
