Propulsionless planar phasing of multiple satellites using deep reinforcement learning

Autor: Melrose Brown, Joshua Abbey, Sudantha Balage, Rasit Abay, Russell Boyce, Brenton Smith

Publikováno v: Advances in Space Research. 67:3667-3682

This work creates a framework for solving highly non-linear satellite formation control problems by using model-free policy optimisation deep reinforcement learning (DRL) methods. This work considers, believed to be for the first time, DRL methods, s

Two-Line Element Estimation Using Machine Learning

Autor: Sudantha Balage, Melrose Brown, Russell Boyce, Rasit Abay

Publikováno v: The Journal of the Astronautical Sciences. 68:273-299

Two-line elements are widely used for space operations to predict orbits with a moderate accuracy for 2-3 days. Local optimization methods can estimate a TLE as long as there exists an initial estimate, whereas global optimization methods are computa

Hypersonic Wind-Tunnel Free-Flying Experiments with Onboard Instrumentation

Autor: Sean O'Byrne, Neil Mudford, David R. Buttsworth, Sudantha Balage, Andrew J. Neely

Publikováno v: Journal of Spacecraft and Rockets. 52:231-242

Hypersonic wind-tunnel testing with “free-flight” models unconnected to a sting ensures that sting/wake flow interactions do not compromise aerodynamic coefficient measurements. The development of miniaturized electronics has allowed the demonstr

A computational fluid dynamics (CFD) based dimensional analysis of the flow in the base region of a planetary re-entry configuration is presented. Reynolds number and free stream Mach number are found to have the dominant influence on the Mach number

Autor: Asier Ania, Max Buneta, Michael Viechweg, Sudantha Balage, Marek Krzeminski, Brian Feeney, Stana Todorcevic, Michael Trauttmansdorff, Vladimir Kudriavtsev

Publikováno v: Computational Technologies for Fluid/Thermal/Structural/Chemical Systems With Industrial Applications, Volume 1.

In the present article we review engineering and research efforts conducted by a group of volunteers with the help of advanced engineering commercial software (CFD-ACE+, ANSYS, CFD-FASTRAN, Matlab/Simulink, Autodesk Inventor, Maple) in support of the
