Flight Article LOX/Paraffin Hybrid Motor
Update: October 2004
Currently work is progressing on a lab-scale gaseous oxygen/paraffin prototype motor. It has been successfully fired several times but there are a few issues like a lower than expected chamber pressure and unusual erosion in the paraffin grain that we are working out.
Started to outline the design philosophy and goals for LOX/Paraffin hybrid
