Simulation procedure in real time of a helicopter rotor

摘要

In this procedure the corresponding equations that determine the movement of the rotor are formulated and the aerodynamic actions for each blade are obtained in each iteration (the forces transmitted to the helicopter and the moments with respect to the articulations), and are solved by discretizations made on the disk of the rotor, so that the blade elements of the partition are linked to the disk, which does not rotate, instead of to each blade. The blades cross a range of azimuth in each iteration, making a division of each blade longitudinally into ne elements , and of the rotor disk in na sectors, corresponding to divisions of the range of azimuthal angles. Partitions are thus made on a blade element, identifying each blade element by its distance from the rotor axis and its azimuth angle.
