Aerospace and Mechanical Engineering2020<p>A noncoplanar controlled heliocentric flight to Venus of a spacecraft with a non-perfectly reflecting solar sail is considered. The aim of the heliocentric flight is to get a spacecraft into Hill sphere of Venus with zero hyperbolic excess velocity. An algorithm has been developed for applying the locally optimal control laws for the fastest change of the osculating elements. Solar sail orientation is controlled by thin-film control elements arranged along the solar sail surface perimeter. The flight trajectory, the control program and the required width and area of thin-film control elements are obtained as a result of motion simulation.</p>Космический аппаратнекомпланарный гелиоцентрический перелёт к Венеренеидеально отражающий солнечный парусматематическая модель движенияпрограмма управлениязакон локально-оптимального управлениятонкоплёночный элемент управленияSpacecraftnoncoplanar heliocentric flight to Venusnon-perfectly reflecting solar sailmathematical motion modelcontrol programlocally optimal control lawthin-film control elementmotion simulation[1.
