build_VLM_surrogates#
- build_VLM_surrogates(aerodynamics, vehicle)[source]#
Build surrogate models for aerodynamic coefficients using VLM analysis results.
This function creates interpolation-based surrogate models for various aerodynamic coefficients across different flight regimes (subsonic, transonic, supersonic).
- Parameters:
aerodynamics (Data) –
- VLM analysis data structure containing training data and vehicle information
- trainingData
Training data with aerodynamic coefficients at different conditions
- vehicleData
Vehicle configuration data
- surrogatesData
Container to store the created surrogate models
- Returns:
Results are stored in the aerodynamics.surrogates data structure
- Return type:
None
Notes
The function creates separate surrogate models for subsonic, transonic, and supersonic regimes. For supersonic and transonic regimes, surrogates are only built if sufficient data points are available (more than 2 Mach points).
The surrogate models use interpolation to predict aerodynamic coefficients at arbitrary flight conditions within the training data range.
Theory
The function uses regular grid interpolation for 2D data (e.g., coefficient vs angle of attack and Mach number) and 1D interpolation for stability derivatives.
