METHODS AND SYSTEMS FOR ASSISTING IN THE DESIGN OF MOBILE SURFACES OF OBJECTS

A computer-aided method suitable for calculating the position of a mobile surface of an object such an aircraft that moves through a fluid medium, which is affected by at least an upstream or downstream object component, for achieving a predetermined value Vo of a predetermined object performance target, including the following steps: preparing a computer-implemented CFD model of the object having said mobile surface in a first position; solving the CFD model and obtaining the value Vi of said object performance target; if the difference between Vi and Vo is greater than a predetermined value, modifying the CFD model changing the position of the mobile surface in the CFD model and iterating the solving step. The invention also refers to a system for carrying out the method.
