Aeroengines

Successful aeroengine designs require varied and complex simulations to ensure that critical safety and lifecycle targets are met. Competing requirements such as increased time between overhaul and reduced weight make detailed and accurate analysis even more critical. Many design factors must be considered including vibration, high temperature, creep, and wear. Composites and exotic alloys are increasingly used in aeroengine design, and their unique properties must be considered for fatigue life requirements.

SIMULIA provides realistic simulation solutions, including the Abaqus Unified FEA product suite, to allow simulation and analysis from early in the design phase through the product lifecycle, maximizing the return on your simulation investment while reducing costs associated with redesign, rework, and additional physical testing. Linear dynamic capabilities for unsteady stress predictions, detailed user-defined material capabilities for incorporating customer developed creep and other material behavior, and a complete set of thermal analysis capabilities make SIMULIA’s aeroengine solution a complete design and analysis tool for next generation engine development.

Solution Capabilities

• State-of-the-art contact capabilities for blade/disk attachment stress prediction, bearing and seal design, and other difficult contact problems
• Thermal boundary conditions that can be specified as an analytic field, allowing temperature, convection, and heat flux to be defined as a function of radial, circumferential, and axial position
• Linear dynamic capabilities including complex eigenvalue extraction for prediction of shaft whirling
• Cyclic symmetry boundary conditions to simplify modeling of periodic structures, including the ability to obtain full 360° modal behavior
• User-defined stress and thermal material behavior capabilities to incorporate your proprietary knowledge of single crystal blades, ceramic matrix composites, and other exotic materials
