Top level technological objectives
- To recreate the industrial loads process using CFD to generate the experimental corrections
- To assess the impact of the underlying assumptions of the current loads process
- To investigate methods to extend the applicability of the current process to highly flexible and innovative structures
- To develop methods to include the uncertainty present in both the aerodynamic and structural models within the current loads process and investigate the impact on gust loads
Description of work
The current industry-standard unsteady gust load prediction is based on the Doublet Lattice Method (DLM) and steady corrections from experimental wind tunnel data. To investigate aspects of this process and how it may be extended for highly flexible and innovative designs, the process will be recreated using CFD. This will enable a direct comparison between the predictions of gust loads from the process and the corresponding free air results from WP2.
Once this investigation has been completed, each component of the process can be assessed individually and alternative approaches investigated that will extend the applicability of the current process to highly flexible and innovative structures. Further for there to be confidence in a virtual loads process for innovative and highly flexible structures where experience of gust loading is not available, levels of uncertainty of the results must be quantified.
