Surrogate modelling

The complex simulation of a typical bird strike analysis starts with simulations of flat, octagonal plates before moving to simulations of different leading edge designs. That plate shape is the same shape used in real life experiments, so these simulations play a key role in validating finite element models. The objective of this case study was to end up with a surrogate model which in the future can be used to identify the overall behaviour of the plate, without a significant loss in quality. This approach will allow performing preliminary investigations for bird impact on wing leading edges without running a full batch of finite element analysis.

Analyzing the behavior of the plate

In the search for a proper surrogate model to replace the time-consuming simulations, the interest is more on the overall behaviour of the plate and less on the actual node-to-node response in time and space. This analysis would take much lesser time than manual iterations using a simulation tool.

Many evaluation parameters can be used to measure the optical performance of a camera system. The Root-Mean-Square (RMS) wavefront aberration is an averaged error measure that describes the gap between the ideal wave front and the actual wavefront. It can be determined from the position and tilt of all lenses in a lens tube.
