Axial Compressor

Key Features and Benefits
  • The scope of axial compressor design and analysis: flow path with normal (rotor-stator) and single row stages, mixed flow (axial/radial) flow path, multi-section flow path, flow path with counter-rotating rotors.

  • Multistage flow path meanline analysis and optimization with support of “as-designed” and “off-design” operational conditions.

  • Meanline analysis of combined axial-radial compressor flow path.

  • Turbomachinery flow path throughflow analysis and stage throughflow analysis with search for optimal blade twist using the optimization methods through design cycle in the interactive mode.

  • Axial compressor analysis and optimization in the “off-designed” mode using the integrated optimizer based on the design-of-experiment (DoE) methodology.

  • Performance map generation including flow path of variable geometry: vanes/blades rotation schedules.

  • Generation, interactive editing, and optimization of the cascades. Flow and boundary layer calculation.

  • 3D airfoil design in the automatic and interactive modes with geometric and strength criteria monitoring; 3D fan and compressor blade design with custom lean and sweep.

  • Custom profiles database.
