Space Forum / Shuttle / February 2006bad landing video
Since there was only one response to my earlier post... here's a video of the STS-3 landing..correct me if I'm wrong but doesn't the landing gear get deployed 19 seconds before touchdown? Counting from the moment the gear doors open to touchdown, it's only 7 seconds...then the nose almost is rotated down but then comes up again.. WTF?? http://spaceflightnow.com/shuttle/features/000414overhaul/sts03_qt.html seems like this was a "close call" > Since there was only one response to my earlier post... > here's a video of the STS-3 landing..correct me if I'm wrong but [quoted text clipped - 4 lines] > http://spaceflightnow.com/shuttle/features/000414overhaul/sts03_qt.html > seems like this was a "close call" They had to increase Columbia's approach and landing speeds due to the elevation at White Sands. There may have been some stiff winds at White Sands on landing day too. There had been a sand storm the previous day. The landing gear were deployed at 270 knots and locked down two seconds before touchdown. The rotation problem was pilot error, aggrevated by the high touchdown velocity. According to: "http://members.aol.com/WSNTWOYOU/STS3MR.HTM" "During nose gear slapdown, the vehicle pitched up to around 6 degrees after having been down to -3 degrees pitch. This occurred because the pilot was preventing premature nosewheel contact. Subsequent analysis has shown the vehicle responded essentially as analysis predicted and as seen on the Ames simulator, both prior to and after the mission, in which nearly identical responses occurred." - Ed Kyle > .... > The rotation problem was pilot error, aggrevated by the high > touchdown velocity. .. I recollect analysis showing the nose gear touchdown rate was close to the design limits. Does anybody else remember that? -- Joe D. > "During nose gear slapdown, the vehicle pitched up to around > 6 degrees after having been down to -3 degrees pitch.
