초록

The invention relates to a method for simulating the unsteady aerodynamic loads being exerted on the external structure of an aircraft, notably in the context of a simulation of the buffeting of a wing surface in an airflow. The method includes a step of measurement of pressure (410) at different points of a grid, a step of calculation of the spectral density at these points (420) followed by extrapolation/interpolation operations to calculate the missing measurements (430), a step of estimation of the pressure coherence (440) for each pair of points of ...

1. A method of simulation by computer of unsteady aerodynamic loads being exerted on an external structure of an aircraft, positioned in an airflow, the method comprising: (a) a step of measurement of pressure by multiple sensors located on the surface of the external structure, and positioned at first plurality of points of a grid having a first direction in a direction of the airflow, and a second direction, separate from the first direction, where the pressure signals of the sensors are stored in a memory;(b) a step of calculation of a spectral densit...
