Simulation of Electro-osmotic Micro Pump Using Dissipative Particle Dynamics

Ramin Zakeri; Rokhshaad Dashti gohari; Esmaeil Yadollahi

Volume 3, Issue 2 , September 2019, Pages 1-9

Abstract
  In this paper, the dissipative particle dynamic method is used to simulate the electrosmotic micro pump as the main part of a spatial-chemical propulsion system. In this simulation, the micro-pump is driven by the principle of  electrosmotic flow.Furthermore,the effective parameters, such as channel ...  Read More

Review of Deployment Mechanisms for Space Structures

Milad Azimi

Volume 3, Issue 2 , September 2019, Pages 23-40

Abstract
  Growing the number of satellites ready to be launched emphasizes the need for reduction of space hardware and subsystems cost, volume, and mass. Realizing these reductions can be implemented deploying new mechanisms for space structures. The performance benefit margin of deploying structures increases, ...  Read More

Application of Advanced Control Systems in Flexible Space Vehicles

samad moradi

Volume 3, Issue 2 , September 2019, Pages 41-51

Abstract
  This paper presents advanced controllers for maneuver and vibration control of dynamic systems with rigid-flexible coordinates. Stability analysis of such a control system is one of the important issues. The control of flexible spacecrafts or flexible manipulators with rigid-flexible body dynamics has ...  Read More

Performance Improvement of Guidance System, Using Lateral Thrusters

Soroush Tahayori; Valiollah Ghaffari; Hasan Mohammadkhani

Volume 3, Issue 2 , September 2019, Pages 59-69

Abstract
  This paper is mainly concentrated on performance improvement and miss-distance reduction in a typical guidance system. These goals would be achieved by adding some attitude control motors (ACM) to the existing guidance algorithm. The ACM system usually contains some disposable thrusters, which are installed ...  Read More
