Resonance ignition devices utilize the gas dynamic phenomenon to heat propellant gases to their auto-ignition temperature in order to initiate combustion. These devices are a promising alternative to current rocket engine ignition systems. In this thesis a python code was developed to generate a resonance ignition system design. The design was tested and parameters characterized using ANSYS Fluent. This resulted in a detailed design of a GOX-Ethanol resonance ignition device that is successful in heating the resonance gas to above its auto-ignition temperature. This project presents the python and Fluent tools developed to conduct this study, analyses the effect of different input parameters on the device, and presents a working detailed design.
