    摘要: This procedure proposes the appropriate equations that determine the rotor movement in order to obtain the aerodynamic actions for each blade in each iteration (the forces that are transmitted to the helicopter and the moments with respect to the articulations), and they are resolved by discretizations made in the rotor disc, such that that the blade elements of the partition are connected to the disc, which does not rotate, instead of to each blade. The blades pass through an azimuth range in each iteration, making a division of each blade longitudinally into ne elements, and the rotor disc into na sectors, corresponding to divisions of the range of azimuth angles. Therefore, partitions are made on ne·na blade elements, identifying each blade element by means of its distance to the rotor axis and its azimuth angle.
