In previous tests I've been running at a higher O/F than I originally intended for this igniter due to initially flawed tools for calculating Cd of the orifices. With this test I swept a range of mixture ratios between approximately 2.00 and 2.45 by throttling the fuel pump pressure mid-test. Prior hotfires suggested that too much liquid fuel could interfere with the igniter performance and stability. The goal of this test was to further investigate that theory. Ultimately the test verified that it is possible to safely run at more fuel-rich ratios which will pose less risk to my hardware.
