Performance evaluation of propulsion systems as LEO deorbiting devices
Journal Title: INCAS BULLETIN - Year 2017, Vol 9, Issue 3
Abstract
This paper evaluates the possibility of deorbiting a launch vehicle upper-stage at end-of-mission from low Earth orbit, by using an additional propulsion system as a means of achieving deorbiting and complying with the “25 years” mitigation regulation. The deorbiting performances of chemical and electrical propulsion are analyzed through a MATLAB code which integrates orbital perturbations such as gravitational acceleration, atmospheric drag and rocket engine/motor thrust. Additionally, the research is placed within a body of similar papers concerned with deorbiting by means of propulsion, by performing a state of the art study.

Forced Flow Patterns in a Miniature Planar Spiral Transformer with Ferrofluid Core
Energy harvesting devices (EHD) utilize small-scale components with low power losses. Key parts, the electric power transformers (EPTs) are to convert the voltage/current electromagnetic parameters from the primary, ener...
Continuous defects: dislocations and disclinations in finite elasto-plasticity with initial dislocations heterogeneities
Within the constitutive framework of second order plasticity, following [4,5], under the assumptions that the plastic distortion is not compatible, and the plastic connection is not compatible with the plastic distortion...
Aerodynamic Analysis of C-Wing Aircraft
In the recent years, the researchers focused on the development of long-range aircraft with the commercial aid of nonconventional design concepts. The C-wing concepts for large aircraft are highly preferred to overcome t...
Unsteady effects at the interface between impeller-vaned diffuser in a low pressure centrifugal compressor
In this paper, Proper Orthogonal Decomposition (POD) is applied to the analysis of the unsteady rotor-stator interaction in a low-pressure centrifugal compressor. Numerical simulations are carried out through finite volu...
Blowdown wind tunnel control using an adaptive fuzzy PI controller
The paper presents an approach towards the control of a supersonic blowdown wind tunnel plant (as evidenced by experimental data collected from “INCAS Supersonic Blowdown Wind Tunnel”) using a PI type controller. The key...
