In this paper, the lunar gravity assist (LGA) is investigated under the planar circular restricted
three-body problem (PCRTBP) and two-body model. In the PCRTBP, the approximate …

The present research studies Swing-By maneuvers combined with the application of an
impulse at the spacecraft periapsis passage. The studies were made for different values of …

In the present paper, we present an analytical description of the powered swing-by
maneuver in the three-dimensional space. To perform this task, new analytical equations are …

The idea of the present paper is to study the swing-by maneuver between one of the planets
of the Solar System and a cloud of particles. This is what happens when a fragmented comet …

This paper has the goal of calculating transfer trajectories between two coplanar orbits using
several impulses, trying to find solutions that reduce the costs related to the fuel …

The dynamics of a fourth body in the sun-planet-satellite system is used to study the
planetary capture and escape. An expression to describe the energy exchange between the …

This work studies transfer between non-coplanar circular orbits around Earth with the space
vehicle performing a powered lunar flyby maneuver. The complete transfer trajectory is …

The main goal of the present paper is to study the lifetime of orbits around moons that are in
elliptic motion around their parent planet. The lifetime of the orbits is defined as the time the …

In this paper, the angular momentum of the test particle during the flyby in the spatial elliptic
restricted three-body problem (ERTBP) is investigated. We focus on the flyby around the …

在引力辅助过程中施加脉冲可以有效地改善变轨效果. 目前只能对施加小脉冲的情况进行近似
计算, 当脉冲大于近拱点速度的1% 时无法进行分析. 针对这一问题, 提出了一种解析分析方法 …
