SpaceX Dragon 2 capsule destroyed in abort motor ground test

01:09:47 -0400: Does Dragon-2 have single fuel and pressuriation system to serve all Draco and Super Draco engines ? I doubt it. The SuperDracos are 'podded' in pairs and each pair is independent from all the others. Much of the text I read says stuff such as "use the same propellants" which could either mean they use the same type of fuel, or that they draw propellands from the same tanks. Hence question. I think each pair of SuperDracos has its own propel lent tanks and pressurization system. Since the system worked for the Dracos during flight, one would want to look at what is different when you need the Super Dracos. (Or perhaps for the succesfull flight, the pressurized it only to the pressure needed by Dracos, knowing SuperDracos would not be used). I'm pretty sure they're totally independent. The pairs of SuperDracos are fully independent from each other. -- "Insisting on perfect safety is for people who don't have the balls to live in the real world." -- Mary Shafer, NASA Dryden |
