[twitter] New test video of Blue’s 550K lbf thrust, ox-rich staged combustion, LNG-fueled BE-4 rocket engine. The test is a mixture ratio sweep at 65% power level and 114 seconds in duration. Methane (or LNG) has proved to be an outstanding fuel choice.

| #1 Exciting, it looks cool but the burn is in an O2 rich environment. First the methane burns: CH4+O2⟶CO2+2H2 Then the hydrogen burns: 2H2+O2⟶2H2O I think in a sparse or forced oxygen environment the primary reaction will complete but the competing secondary reaction will have insufficient O to complete resulting in an overall reaction of CH4+O2⟶CO2+H2O+H with hydrogen as a unregulated waste product. |
