On 13 November SpaceX successfully completed a series of static fire engine tests of the Crew Dragon spacecraft, a test we know of as these Flight Abort Tests. Trials of the Crew Dragon's Superdraco Thrusters at 3pm Happened.
SpaceX reported this by tweeting that the "full-term" static-fire testing of the launch escape system has been completed, with both SpaceX and NASA reviewing the data. Static-fire testing was conducted at Cape Canaveral Air Force Station in Florida, NASA said in its statement, that eight Superdreco engines fired for about nine seconds. Earlier engines of SpaceX's Landing Zone 1 were tested, and those engines were fired, firing two of the 16 smaller Draco thrusters twice and each time for a second. Draco thrusters are used for on-orbit maneuver and approach control, and will also be used for re-orientation during some in-flight launch escapes. SpaceX has designed the SuperDraco's engines to accelerate, so that the F9 can be taken away from the launch vehicle in an emergency after lift.
Immediately after the SuperDraco engine was shut down, the thrusters' protective flaps closed, two Dracos thrusters fired, those two Dracos thrusters fired to emulate. And all eight SuperDraco flaps closed.The full sequence, from the SuperDraco startup to the flap closure, lasted about 70 seconds.Earlier, on April 20, SpaceX was preparing for a similar static-fire test, with another crew dragon spacecraft that first flew the Demo-1 from the International Space Station without a mission in March.During the "Anomaly", the spacecraft was completely destroyed. In July, NASA and SpaceX announced, the failure was linked to a leaking incident to the SuperDraco propulsion system that allowed nitrogen tetroxide oxide into the helium tube when unexpected shock caused by a shock of liquid propellant in a high-flow helium pressure system Resulted in a titanium ignition incident, resulting in an explosion.The Investigation Team, consisting of SpaceX and NASA personnel, determined that a titanium ignition incident occurred unexpectedly, resulting in an explosion.SpaceX now redesigned the components of the system, eliminating the possibility of slugs entering those high-flow pressure systems.
