Active Space Debris Removal System
Journal Title: INCAS BULLETIN - Year 2017, Vol 9, Issue 2
Abstract
Since the start of the space era, more than 5000 launches have been carried out, each carrying satellites for many disparate uses, such as Earth observation or communication. Thus, the space environment has become congested and the problem of space debris is now generating some concerns in the space community due to our long-lived belief that “space is big”. In the last few years, solutions to this problem have been proposed, one of those is Active Space Debris Removal: this method will reduce the increasing debris growth and permit future sustainable space activities. The main idea of the method proposed below is a drag augmentation system: use a system capable of putting an expanded foam on a debris which will increase the area-to-mass ratio to increase the natural atmospheric drag and solar pressure. The drag augmentation system proposed here requires a docking system; the debris will be pushed to its release height and then, after un-docking, an uncontrolled re-entry takes place ending with a burn up of the object and the foam in the atmosphere within a given time frame. The method requires an efficient way to change the orbit between two debris. The present paper analyses such a system in combination with an Electric Propulsion system, and emphasizes the choice of using two satellites to remove five effective rockets bodies debris within a year.

Implementation of the panel method to the solution of flow around aircraft
In this study a panel method is used as a numerical technique for the solution of the potential three dimensional flows about a complete aircraft configuration to determine the aerodynamic characteristics. This approach...
Numerical analysis for the influence of the geometrical and mechanical parameters on the stiffness and strength of the composite bolted joints
The paper deals with the influence of the geometric (joint clearance) and mechanical parameters (bolt preload, axial force applied to the joint) on the stiffness and strength of the single-bolt, single-shear laminated co...
Test Rig Adaptation for WT Measurements for OR&TP Configurations
The need to test large models at maximum speed regimes close to 100 m/s, for which the aerodynamic forces and moments occurring on the model far exceed the measuring capability of the existing TEM external balance, made...
Analysis of isogrid reinforced cylindrical vessels in the case of axially symmetric buckling
Isogrid structures are a configuration of stiffeners of different sections, which make up a lattice placed on thin plates, with the aim of increasing the buckling factor of the overall structure. Because of the major ben...
