The paper considers the problem of determining accessible landing areas on surface Venus and possibility expanding them by extending launch windows in period from 2026 to 2031, taking into account constraints payload mass maximum overload level acting lander during descent Venusian atmosphere. We used Venera-D planned mission requirements as initial data set for our studies. reaching planet first second half-orbits heliocentric Earth-Venus transfer orbits was explored. It confirmed that...
The paper considers the problem of finding accessible areas on Venus surface and prospect their increasing by extension launch windows during period from 2026 to 2031; taking into account restrictions payload weight maximum overload level affecting lander descent in atmosphere. project Venera-D mission is used as initial data for work. possibility reaching planet first second half-turns heliocentric transfer orbit analyzed. As an example, effect window expansion 2031 nature changes landing...
The article analyzes the biomechanical aspects of load pin design in different conditions its operation; It shows critical situation, causing a voltage limiting tooth root.
The paper considers calculating the periods of radio signal transmission through atmosphere Venus between a small spacecraft placed in limited orbit vicinity collinear libration point Sun-Venus system and orbiter. problem arises framework project under discussion to study Venus. possibility transfers these spacecrafts required orbits various initial conditions is also studied. impulses for transferring specified at selected state vector, most suitable solving this are calculated. duration...
Россия В работе проанализированы возможности перелета на орбиту вокруг транслунной точки либрации с использованием гравитационного маневра около Луны.Проведены исследования орбит, которые может попасть аппарат без применения промежуточных маневров после облета Луны.В смоделирован перелет парковочной околоземной орбиты различные орбиты.Построены цветовые карты характеристик, зависимых от параметров и карта, отражающая области плоскости, соответствующие квази галоорбитам, при движении по...
Abstract Spacecraft missions to the collinear libration points of Sun-Earth system have long proved scientific merit by providing valuable observational data. The unstable nature orbits around mentioned in space requires development control strategies for such order hold spacecraft vicinity points. We investigate a possible strategy on halo L1 and L2 aiming evaluate station keeping performance. station-keeping is based elimination component motion periodical velocity corrections performed...
