Transfer Orbits in the Earth – Moon System and Refinement to Jpl Ephemerides

We describe how to determine transfers between libration point orbits and either the surface of the Moon or a Low Earth Orbit within the Circular Restricted Three – Body Problem (CR3BP) assumptions. Moreover, we explain how to refine such trajectories to ones verifing more comprehensive equations of motion. We are interested in seeing how the geometry of the nominal target orbits and of the ass...

Relative Periodic Orbits of Symmetric Lagrangian Systems

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Orbits on Lagrangian Grassmanian

The purpose of this note is to give a classification of the orbital structure of certain reductive group actions on the Lagrangian Grassmanian. The groups under consideration are Sp × Sp and GL. In general, the finiteness of orbits is known ( [8], [1], [9], [2], [10]). However, the homogeneous structure of each individual orbit is not known except perhaps the generic open orbit 1. The main resu...

Computation of Three-Dimensional Periodic Orbits in the Sun-Earth System

From the last few decades, the space science community has shown considerable interest in missions which take place in the vicinity of the Lagrangian points in the restricted three-body problem (RTBP) of the Sun-Earth and the Earth-Moon systems [1]. Designing trajectories for these missions is a challenging task due to inadequacy of the conic approximations. The RTBP deals the situation where o...
