Abstract

The article describes the trajectory scenario for the Venera-D mission. The main aspects of optimal launch dates are considered. A scenario, which enables insertion of an orbiter into a highly elliptical orbit and a lander on the surface of Venus is described. Characteristics of the choice for operational orbit and scenario ensuring scientific data transfer from the lander on the surface of Venus to the Earth are justified. In addition, possibilities of transfer of a small satellite to the vicinity of the collinear Lagrangian point of the Sun-Venus system, and also a subsatellite into the orbit of the main orbiter, are considered.

Venera-D任务场景和轨迹

摘要

本文介绍了Venera-D任务的轨迹方案。考虑了最佳发射日期的主要方面。描述了一种方案，该方案能够将轨道器插入高度椭圆形的轨道，并将着陆器插入金星表面。合理的选择运行轨道和场景的特征，可确保科学数据从金星表面的着陆器传输到地球。另外，考虑了将小卫星转移到太阳-金星系统的共线拉格朗日点附近以及将子卫星转移到主轨道器轨道中的可能性。
