  A state-of-the-art large eddy simulation code has been developed to solve
compressible flows in turbomachinery. The code has been engineered with a high
degree of scalability, enabling it to effectively leverage the many-core
architecture of the new Sunway system. A consistent performance of 115.8
DP-PFLOPs has been achieved on a high-pressure turbine cascade consisting of
over 1.69 billion mesh elements and 865 billion Degree of Freedoms (DOFs). By
leveraging a high-order unstructured solver and its portability to large
heterogeneous parallel systems, we have progressed towards solving the grand
challenge problem outlined by NASA, which involves a time-dependent simulation
of a complete engine, incorporating all the aerodynamic and heat transfer
components.
