Feasibility Study of Plasma Torch for RCS Thrusters based on Low Energy Consumption
- To understand the theory behind plasma physics and utilize this foundation for the development of an efficient igniter system for Reaction Control System (RCS) thrusters.
- Team lead for this research project which was in collaboration with engineering mentors and an assistant.
- Design optimization process was used to minimize the development costs by analyzing numerous industrial plasma torches based on gas dynamic and heat transfer equations
- Designing various AC and DC power systems for finding a suitable electric system as a plasma driver and in development of a data acquisition system (NI-DAQ) with corresponding control software (LabVIEW).
- Designing a specialized low pass filter circuit for eliminating electromagnetic interference (EMI) for a data acquisition system (NI-DAQ).
- Developing successful mass flow rate calculations for a complex geometry of the torch and piping network with hydraulic principles.
- Conducting performance-estimation and system-efficiency analysis for the plasma torch by MATLAB.
- Achieving high overall system stability by breaking all components down into multiple small scale systems and proving their functional characteristics.
- Modeling the plasma torch head and sub-system assemblies with SolidWorks
Design Projects
20N Thruster Design (Individual Research Project at Boeing)
- Developing a simplified design process to reduce cost and time to increase the efficiency of performance estimation for small scale thrusters
- This project includes understanding the details of compressible gas behavior and chemical reaction characteristics
- The design of liquid propulsion system was constructed with the aid NASA Chemical Equilibrium with Applications (CEA).
