02/2012 – present Mechanical and Aerospace Engineering, California State University, Long Beach, USA
Development Engineer / Research Analyst
Develops a multi-thruster aerospike engine using LOX/propylene to be integrated into a pressure-fed two-stage-to-orbit nanosat launch vehicle.
• Identifies superior components, techniques and materials in accordance with project requirements by 1) performing multidisciplinary trade studies and numerical simulations.
• Designs and configures subcomponents such as thrusters, plug, injector, feed lines and supporting structures with NX Unigraphics.
• Develops curved thrusters, which lead to an increase in overall performance of 4% compared to a generic thruster layout by increasing the total area ratio.
04/2005 – 01/2012 Institute of Aerodynamics, RWTH Aachen University, Germany
Performednumerical simulations, analyzed and interpreted flow structures in the base region of a linear scramjet engine and of generic cylindrical launch systems in the framework of national research projects with participation of the German Aerospace Center and EADS Astrium GmbH.
• Adapted an in-house flow solver written in Fortran and implemented subroutines to simulate time accurate, multi-species, compressible base flows in the transonic and supersonic flow regime using Large-Eddy Simulations.
• Post-processed data using self-written Fortran programs and Tecplot to analyze flow properties and heat fluxes in the time and frequency domain.
• Identified and quantified temporally resolved recirculating flow structures causing mechanical and thermal loads in the base region of different spacecraft.
• Developed subsequent research projects and acquired appropriate fundings.
• Supervised and mentored several graduate and Ph.D. students.
• Managed and conducted project meetings and public project events.
• Published results and presented findings at national and international conferences.
10/2003 – 04/2004 EADS Space Transportation, Ottobrunn, Germany
Intern in the predevelopment department.
• Adapted an Excel simulation program to predict pressure losses and heat transfer of coolant of a sub-scaled VULCAIN II and a VINCI engine.
• Assisted in the setup of hardware for hot-fire tests of a sub-scaled VULCAIN II engine at Lampoldshausen, Germany.
10/ 2002 – 08/2003 Institute of Aeronautics and Astronautics, RWTH Aachen University, Germany
Student Assistant in a Collaborative Research Center dealing with basic research and technologies for two-stage-to-orbit vehicles.
• Implemented Fortran programs determining the change of center of gravity and moments of inertia by consuming propellants during ascent of a TSTO spacecraft.
• Optimized TSTO tank layout which led to an enhanced maneuverability.
