AI fluid simulation for aircraft aerodynamic design
COMAC's chief scientist reported a 24-fold speedup in aerodynamic simulation
Problem
Aerodynamic simulation for the C919 required substantial supercomputing resources. COMAC sought faster calculation methods for aircraft development.
Approach
COMAC and Huawei developed an industrial fluid-simulation model using Huawei's Ascend AI hardware and software. They encoded and preprocessed flow data, extracted features and trained the model. COMAC's chief scientist described the simulation result at a design conference in September 2022.
Results
Takeaway
The reported improvement concerned individual simulations. It did not establish an equivalent reduction in the aircraft's overall development schedule.
