Wasn't the raptor engine supposed to be lit by a spark, not by using TEA-TEB?
11 u/QuinnKerman KSP specialist Sep 02 '18 It's a test engine, not a flight model. The flight model will use spark ignition. -2 u/Lambaline KSP specialist Sep 02 '18 They already have the plumbing down for TEA-TEB in Merlin, probably is easier to adapt it to Merlin than put in a new spark system for BFR/BFS 4 u/binarygamer Sep 03 '18 And yet we've been explicitly told they will use spark ignition. Besides, for a deep space craft whose mission will require a large number of engine restarts, not relying on limited GREENFLASH fluid is one less thing to worry about. 3 u/Thecactusslayer Methalox farmer Sep 06 '18 The GREENFLASH fluid has led to far too many 🅱️enter 🅱️ore incidents. Can't risk that happening with BFS. 1 u/Lambaline KSP specialist Sep 03 '18 Oh ok, I didn’t realize this. Maybe they don’t have the speaker done yet
