CFD Analysis & CAD Comparison

Computer simulations are used to optimize aircraft design during the development phase. GOM's ATOS 3D digitizer supplies dense and precise polygon mesh representations of an aircraft's "as built" condition to obtain a realistic matching CFD analysis. The 3D data is also valuable for symmetry checks and for detecting damage to working prototypes, caused for example by hard landings.

Material, Jointing & Component Testing

Optical metrology analyzes the mechanical properties and behavior of materials, joints and components. GOM's ARAMIS and PONTOS sensors can be integrated into existing test environments, test stands and testing machines. The non-contact sensors measure full-field 3D strain and deformation of soft and rigid materials under mechanical or thermal load. Thus conventional extensometers and strain gauges can now be replaced by GOM's real-time 3D surface deformation analysis.

FEM Deformation Verification

GOM's deformation measurement systems are widely used throughout the aerospace industry to measure and verify deformations in lightweight structures during operation. The systems are easy to integrate into test environments such as climate chambers, wind tunnels, fatigue test stands, etc. In addition, GOM software supports numerical result verification of the captured full-field 3D data.
