Resonant Orbits in the Problem of Expanding the Reachable Landing Areas on the Surface of Venus

We consider the concept of applying gravity assist maneuvers near Venus using resonant orbits with a period equal to the Venusian one. We show that the proposed operations based on this concept allow the reachable landing areas on the surface of Venus to be expanded radically. The price of this approach is an increase of the time interval needed to solve this problem by a value equal to the orbital period of Venus. The cost of the characteristic velocity in this case remains within limits close to the standard variants of planning missions to Venus.
