"Conceptual Design and Data Visualizations for Georgia Tech Interuniversity Mission Operations Control Center (GTMOCC) for Cubesat Missions"
As Georgia Tech expands its space systems capabilities with current and planned future Cubesat Missions, it requires a strong foundation for mission operations to be able to send commands and downlink telemetry from these systems. GT-1 and TARGIT are scheduled to be the first customers of the MOCC, however this system will be designed for versatility to accommodate multiple future missions including GT-2+, and formation flying mission like SWARM-EX and VISORS. This presentation aims to provide a proposed layout of how data received from the satellites will be processed to generate mission critical visualizations, and describe the different MOCC operating modes. Integrating AGI Systems Tool Kit along with MATLAB will provide the functionality to propagate estimated orbits for the satellites and calculate access data regarding when estimated next passes occur in order to aid the operations team in changing operating modes.

"Numerical Simulation of Reacting Flows in a 7-injector GCH4/GOX Rocket Engine"
Utilizing hydrocarbon fuels for rocket engines is beneficial in terms of cost, reliability, and environmental friendliness. To enable more informed and cost-effective designs of rocket engines, it is key to understand the combustion processes involved in the combustion chamber; one approach to do so is through numerical simulations. Numerical simulations facilitate deeper exploration of the physics involved in comparison to experiments. In this study, the numerical simulation of a 7-injector, GCH4/GOX, experimental rocket engine (developed at the Technical University of Munich) is performed with an in-house LES CFD solver. The numerical methodology adopted is based on the well-established, second-order accurate (in both space and time) finite-volume solver for the unsteady Favre-filtered multi-species compressible Navier-Stokes equations. A hybrid scheme, which switches between a second-order-accurate central scheme and a third-order-accurate MUSCL (Monotone Upstream-centered Schemes for Conservation Laws) scheme is employed. The reacting flow and flame features/characteristics are studied from the simulation results.
