Craig Posted December 21, 2011 Share Posted December 21, 2011 http://www.nasa.gov/...chute_test.html HOUSTON -- NASA successfully conducted a drop test of the Orion crew vehicle's parachutes high above the Arizona desert Tuesday in preparation for its orbital flight test in 2014. Orion will carry astronauts deeper into space than ever before, provide emergency abort capability, sustain the crew during space travel and ensure a safe re-entry and landing. A C-130 plane dropped the Orion test article from an altitude of 25,000 feet above the U.S. Army's Yuma Proving Grounds. Orion's drogue chutes were deployed between 15,000 and 20,000 feet, followed by the pilot parachutes, which then deployed two main landing parachutes. This particular drop test examined how Orion would land under two possible failure scenarios. Orion's parachutes are designed to open in stages, which is called reefing, to manage the stresses on the parachutes after they are deployed. The reefing stages allow the parachutes to sequentially open, first at 54 percent of the parachutes' full diameter, and then at 73 percent. This test examined how the parachutes would perform if the second part of the sequence was skipped. The second scenario was a failure to deploy one of Orion's three main parachutes, requiring the spacecraft to land with only two. Orion landed on the desert floor at a speed of almost 33 feet per second, which is the maximum designed touchdown speed of the spacecraft. Since 2007, the Orion program has conducted a vigorous parachute air and ground test program and provided the chutes for NASA's successful pad abort test in 2010. Lessons learned from this experience have improved Orion's parachute system. For images of the drop test, visit: http://www.nasa.gov/..._test_drop.html.

BAZ Posted December 21, 2011 Share Posted December 21, 2011 Blimey, 33ft/sec is 22.5 mph, that's going some if you are hitting the ground. Link to comment Share on other sites More sharing options...
Craig Posted December 21, 2011 Author Share Posted December 21, 2011 Yup, I wouldn't want to be in the module coming down at that speed. Link to comment Share on other sites More sharing options...
+Rusty Strings Posted December 22, 2011 Share Posted December 22, 2011 I can't help thinking that after 40 years, NASA could have come up with a new spacecraft that didn't look like an Apollo command module. Link to comment Share on other sites More sharing options...
Guest Kheldar Posted December 22, 2011 Share Posted December 22, 2011 (edited) I can't help thinking that after 40 years, NASA could have come up with a new spacecraft that isn't an Apollo command module. Fixed it for you, the whole damn program is reuse and recycle!! Come on NASA, get your act together Edited December 22, 2011 by Kheldar Link to comment Share on other sites More sharing options...
