AI Technical Summary
Existing technologies face bottlenecks in accuracy and efficiency when predicting and matching the tip clearance of ceramic matrix composite turbine outer rings, making it impossible to achieve efficient and accurate forward design.
An optimization strategy based on reward function and reward gradient, combined with deep learning and finite element analysis, is adopted to construct a fast prediction model for turbine outer ring blade tip clearance. The design parameters are optimized through an Actor-Critic strategy network to achieve intelligent matching of blade tip clearance.
This technology enables high-precision and rapid prediction and optimization of the blade tip clearance of the outer ring of a ceramic matrix composite turbine, improving the overall efficiency and stability of the engine while reducing computational workload and time.
