1 00:00:00,000 --> 00:00:07,237 Sound FX music 2 00:00:07,272 --> 00:00:09,213 When you’re designing the world’s 3 00:00:09,248 --> 00:00:10,501 most powerful rocket ever there’s 4 00:00:10,536 --> 00:00:12,725 a million different things to think about. 5 00:00:12,760 --> 00:00:14,853 Here at Marshall l Space Flight Center 6 00:00:14,888 --> 00:00:16,628 we are considering all of those things 7 00:00:16,663 --> 00:00:17,997 in support of the Space Launch 8 00:00:18,032 --> 00:00:20,221 System. One of those things is 9 00:00:20,256 --> 00:00:21,990 the lift off environment produced 10 00:00:22,025 --> 00:00:23,638 by the rocket. Marshall l Space 11 00:00:23,673 --> 00:00:25,701 Flight Center in coordination with 12 00:00:25,736 --> 00:00:27,021 other centers such as Langley 13 00:00:27,056 --> 00:00:28,300 and Kennedy Space Center have 14 00:00:28,335 --> 00:00:30,829 designed this test setup in order 15 00:00:30,864 --> 00:00:32,965 to answer the questions of what 16 00:00:33,000 --> 00:00:34,797 are the lift off environments 17 00:00:34,832 --> 00:00:36,364 produced by the vehicle; what are 18 00:00:36,399 --> 00:00:38,317 the lift off environments seen by 19 00:00:38,352 --> 00:00:40,117 the tower and the mobile launch 20 00:00:40,152 --> 00:00:42,405 pad and what are the water sound 21 00:00:42,440 --> 00:00:44,653 suppression systems needed in 22 00:00:44,688 --> 00:00:46,653 order to mitigate the sound levels. 23 00:00:46,688 --> 00:00:48,221 The design you see back here has 24 00:00:48,256 --> 00:00:50,125 four liquid engines each having 25 00:00:50,160 --> 00:00:51,621 twelve hundred pounds of thrust 26 00:00:51,656 --> 00:00:53,533 …and two solids on either side 27 00:00:53,568 --> 00:00:55,021 each having approximately nine 28 00:00:55,056 --> 00:00:56,189 thousand pounds of thrust. 29 00:00:56,224 --> 00:00:58,494 So during my design I had to hold 30 00:00:58,529 --> 00:01:00,830 that total of approximately 31 00:01:00,865 --> 00:01:03,221 twenty-five thousand pounds of 32 00:01:03,256 --> 00:01:04,901 thrust in place so that it doesn’t 33 00:01:04,936 --> 00:01:06,437 fly away and injure someone. 34 00:01:06,472 --> 00:01:08,901 Our scale model rocket is amazing 35 00:01:08,936 --> 00:01:11,342 and our designer did a fabulous job of 36 00:01:11,377 --> 00:01:14,270 it and it’s an amazing piece of work. 37 00:01:14,305 --> 00:01:17,269 And inside that vehicle there is roughly 38 00:01:17,304 --> 00:01:19,468 over two hundred and fifty different 39 00:01:19,503 --> 00:01:22,100 ports for microphone and pressure 40 00:01:22,135 --> 00:01:24,301 transducer measurements. And each 41 00:01:24,336 --> 00:01:26,261 of those microphone measurements 42 00:01:26,296 --> 00:01:28,389 has a special little holder to hold the 43 00:01:28,424 --> 00:01:30,589 microphone in place. It’s an 44 00:01:30,624 --> 00:01:31,973 engineering marvel. 45 00:01:32,008 --> 00:01:40,109 Rocket sounds. 46 00:01:40,144 --> 00:01:41,509 Very loud sounds can be very 47 00:01:41,544 --> 00:01:43,797 damaging both to the rocket vehicle 48 00:01:43,832 --> 00:01:44,765 and to the crew. The collection of 49 00:01:44,800 --> 00:01:46,693 this data has been very important 50 00:01:46,728 --> 00:01:48,813 to every launch vehicle we’ve 51 00:01:48,848 --> 00:01:50,253 ever designed and it’s especially 52 00:01:50,288 --> 00:01:52,533 important when you’re designing
