12-13-2022 High Flux PLA/KMnO4 Fuel Core Test

This month I tested a 13.5 cm high flux PLA/KMnO4 fuel core. The objective of this test was to increase the O/F ratio. Ignition occurred in ~ 1.3 sec with ~ 4.2 sec of thrust. From the video, I was able to deduce the mass flow rate. As such, the O/F ratio was ~ 4.0. The L/D was 8.8 and the initial surface flux was ~ 0.24 gm/cm2/sec. From the test, it appears as though the L/D is the dominate parameter as opposed to the initial surface flux.
