초록

A computer-aided method suitable for assisting in the design of an aircraft by providing relevant dimensioning values corresponding to an aircraft component in transonic conditions inside a predefined parameter space by means of a reconstruction of the CFD computations for an initial group of points in the parameter space using a POD reduced-order model, comprising the following steps: a) Decomposing for each flow variable the complete flow field into a smooth field and a shock wave field in each of said computations; b) Obtaining the POD modes associate...

1. A computer-aided method suitable for assisting in the design of an aircraft by providing dimensioning aerodynamic forces, skin values or values distributions around an airfoil corresponding to an aircraft component in transonic conditions inside a predefined parameter space by means of a reconstruction of previously performed CFD computations for an initial group of points in the parameter space using a reduced-order model, generated by computing Proper Orthogonal Decomposition (POD) modes of flow variables and obtaining POD coefficients using a genet...
