Abstract

The generalized parametric model is given to calculate the evolution of vortex wake behind an aircraft. Using this model the method has been developed for correcting the trajectory of the aircraft during its movement in a vortex wake behind an aircraft-generator. We consider two types of flat-plane maneuvers of an aircraft-follower with subsequent returning to the original trajectory: in the vertical and horizontal planes. An algorithm has been developed to ensure the vortex safety of an aircraft-follower using criterion of minimum deviation of an follower of the original trajectory.
