Engineering Simulation Solutions for the Aerospace Industry

Aircraft Engines and Gas Turbines

Large and small aeroengines, aeroderivatives, auxiliary power units and industrial gas turbines play an important role in the transportation and power generation industries. Customers now require manufacturers to deliver technologically advanced, efficient and better performing products which meet new standards in terms of increased reliability, reduced cost, lower fuel consumption, reduced emissions and low noise. Global competition is intense and the ability to deliver superior machines ahead of the competition is essential for survival. Leading manufacturers have adopted Simulation Driven Product Development from ANSYS as a key enabler for meeting these demanding goals.

ANSYS computer-aided engineering (CAE) software is used for a wide range of gas turbine applications, including:

  • Aircraft engine fan 
  • Combustor analysis
  • Compressor and turbine bladed flow path computational fluid dynamics (CFD) analysis
  • Cavity analysis
  • Heat transfer and thermal stress analysis
  • Inlet and exhaust diffuser analysis
  • Under-cowl fluid flow and heat transfer management
  • Installation aerodynamics
  • Rotordynamic and bearing analysis
  • Secondary flow path analysis
  • Structural and modal analysis of all components (finite element analysis, or FEA)
  • Turbine blade cooling, film cooling and durability studies

The unequalled depth and unparalleled breadth of ANSYS products provides designers and analysts with the greatest range of functionality, applicable to all of the complex physical phenomena encountered in modern gas turbine engines. For instance, the ANSYS computational fluid dynamics (CFD) solvers ANSYS CFX and FLUENT provide all the necessary turbulence and combustion models for high-fidelity simulation of steady and unsteady, rotating and stationary frame, swirling, accelerating, diffusing, combusting, subsonic and supersonic flows with shocks, mixing and sprays. Similarly, ANSYS Mechanical, ANSYS Multiphysics, ANSYS AUTODYN and ANSYS LS-DYNA provide designers with with the necessary tools for linear and non-linear stress analysis of simple and composite materials, contact, dynamics, rotordynamics, conjugate heat transfer and thermal stress analysis.

ANSYS gas turbine tools are part of the ANSYS Workbench environment, ensuring start-to-finish, multiphysics workflow and seamless CAD connection. Productivity-enhancing tools such as ANSYS ICEM CFD, ANSYS TurboGrid and ANSYS BladeModeler, as well as turbomachinery-specific pre- and post-processing deliver true Simulation Driven Product Development performance in a flexible, open environment.
