“…It should be noted here that the authors' calculations in the General Mission Analysis Tool (GMAT) [26] show that the value of such correction maneuvers will not exceed about 10-20% of total ∆V. If we refer to the experience of the BepiColombo [27,28], InterHeliozond [29,30] (under development), and other missions, with multiply gravity assists, the additional correction maneuvers for our mission concept with one gravity assist will be significantly lower. However, it should be emphasized that in our simulation using a model including gravitational attraction of all the Solar System planets, oblateness of Earth and Venus, as well as solar radiation pressure the date of Venus flyby differs from the one obtained using the method of patched conic approximation, but in general such shift for this problem is of the order of a few hours.…”

“…The formulas obtained in [1][2][3] for the orbital inclination of the spacecraft and its change as a result of gravity assist maneuvers (GM) around the planet are generalized for the case when not only the spacecraft's orbit, but also the planet's orbit is elliptical. The geometric interpretation of the formulas is described.…”

“…In previous works [1][2][3], the authors conducted a comparative analysis of various modern astrodynamics developments [4][5][6][7][8], affecting the 3D spatial implementation of gravity assists, in order to clarify the possibility of their application, taking into account the exact ephemeris. In [3] a refined analytical formula of the inclination changes of the SC orbit were obtained for one-pass 3D GA obtained and the results of calculations by using the parameters changes of the orbital inclination of the SC relative the Solar system planets and their satellites. In this paper, the main focus is on the development of algorithms for the synthesis of multi-pass GA chains, the use of which leads to a significant increase in the inclination of the SC orbit above the ecliptic plane.…”

An effective space exploration is impossible without gravity assists (GA) using. Their application relaxes the constraints imposed on the space mission scenarios by the characteristic velocity budgets being realized at the current stage of development of space technology. A significant change in the inclinations of operational spacecraft (SC) orbits in flight aimed at studying the inner heliosphere from out-of ecliptic positions (the ESA “Solar Orbiter” mission, Russian “Interheliozond”) is needed to accomplish some prospective space missions. Low-cost tours for the high inclined orbit formation in the Solar system with use of gravity assists near its planets (Earth and Venus) with the full ephemeris using are considered. The limited dynamic possibilities of using gravity maneuvers require their repeated performance. Based on the formalization of the search for the GA- timetables with subsequent adaptive involvement of a large number of options, a high-precision algorithm for synthesizing chains of increasing gravity assists was built. Its use leads to a significant inclination change of the research SC's orbit without significant fuel consumption during a reasonable flight time.

Expanding Possible Landing Areas on the Surface of Venus by using Gravity Assist Maneuvers

In the framework of the project "Venera-D" a problem of landing the descent module in a given area of the surface of Venus is considered. With the standard approach to selection of the launch window and with limitations on the value of the re-entry angle into the atmosphere, as well as on the maximum allowable overload for lander during descent, a significant part of the planet’s surface is inaccessible for landing. The simplest way to expand the landing area could be to increase the launch window by moderate reducing the payload mass. However, the potential for such an increase is significantly limited, primarily by the required characteristic velocity cost. In this study a new approach is proposed to ensure landing of the descent module at any point on the surface of Venus. The basis of the proposed approach is the use of the gravitational field of the planet to transfer the spacecraft to the heliocentric orbit, resonant at a ratio of 1:1 with the orbit of Venus, and the subsequent return to its original position in one Venusian year, when another part of the surface will be available for landing. In the presented paper it is shown that application of new approach allows to provide radical expansion of achievable landing areas, and also to provide access to any point on the surface of Venus due to increase of duration of flight and small increase of characteristic velocity costs
