1 00:00:22,889 --> 00:00:20,519 echo man this thing is huge you could 2 00:00:26,130 --> 00:00:22,899 park a bus in here bill come on we got a 3 00:00:28,079 --> 00:00:26,140 show to do oh sorry hi I'm bill hubscher 4 00:00:29,880 --> 00:00:28,089 and I'm Lori Meggs and welcome to focus 5 00:00:32,190 --> 00:00:29,890 on Marshall on today's episode we are 6 00:00:33,330 --> 00:00:32,200 standing outside a gigantic oven here at 7 00:00:35,460 --> 00:00:33,340 the marshall center and we're going to 8 00:00:36,720 --> 00:00:35,470 show you what's baked in here but first 9 00:00:38,340 --> 00:00:36,730 we're going to take you to two brand new 10 00:00:39,750 --> 00:00:38,350 facilities here at Marshall that are 11 00:00:42,180 --> 00:00:39,760 going to help in the development of 12 00:00:43,740 --> 00:00:42,190 future spacecraft what are the greatest 13 00:00:45,180 --> 00:00:43,750 things about this job is how you can 14 00:00:46,740 --> 00:00:45,190 learn something new every day for 15 00:00:48,540 --> 00:00:46,750 example I always thought the external 16 00:00:50,280 --> 00:00:48,550 tank was built entirely down to the 17 00:00:52,590 --> 00:00:50,290 Michoud assembly facility in New Orleans 18 00:00:54,360 --> 00:00:52,600 not true the nose cones are built right 19 00:00:55,650 --> 00:00:54,370 here at Marshall Richard launches a 20 00:00:58,110 --> 00:00:55,660 supervisor in the non-metallic 21 00:00:59,790 --> 00:00:58,120 processing area and Richard first of all 22 00:01:01,860 --> 00:00:59,800 what is this material we're seeing here 23 00:01:06,389 --> 00:01:01,870 that is part of the nose cone right the 24 00:01:10,109 --> 00:01:06,399 material is at its a graphite fiber whoa 25 00:01:12,719 --> 00:01:10,119 it into a fabric with a phenolic resin 26 00:01:15,179 --> 00:01:12,729 impregnated into that fabric in fact I 27 00:01:18,450 --> 00:01:15,189 have a small piece here of the material 28 00:01:20,700 --> 00:01:18,460 it's very high strength very flexible 29 00:01:23,160 --> 00:01:20,710 and it needs to be flexible so that we 30 00:01:26,520 --> 00:01:23,170 can put it into the nose cone form it 31 00:01:29,550 --> 00:01:26,530 around some of the corners and cavities 32 00:01:32,760 --> 00:01:29,560 that are in the nose cone the material 33 00:01:37,349 --> 00:01:32,770 is actually the fiber is actually made 34 00:01:40,529 --> 00:01:37,359 in Tennessee though it's taken to South 35 00:01:42,300 --> 00:01:40,539 Carolina and woven into a fabric then 36 00:01:44,279 --> 00:01:42,310 shipped to california and there's a 37 00:01:47,160 --> 00:01:44,289 resin is made New York and that's 38 00:01:49,349 --> 00:01:47,170 shipped to california and then pre 39 00:01:52,050 --> 00:01:49,359 impregnate this material and then that 40 00:01:53,910 --> 00:01:52,060 material is shipped here to Marshall for 41 00:01:56,099 --> 00:01:53,920 us to lay up in the nose cone it's 42 00:01:57,209 --> 00:01:56,109 really a nationwide effort so walk us 43 00:01:59,699 --> 00:01:57,219 through the steps what are these guys 44 00:02:02,819 --> 00:01:59,709 doing right here these guys are actually 45 00:02:04,949 --> 00:02:02,829 doing the cut out of each ply we do 46 00:02:09,359 --> 00:02:04,959 little pie shape so that it fits into 47 00:02:11,520 --> 00:02:09,369 the cone itself and we have done many 48 00:02:13,530 --> 00:02:11,530 years of development for this to make 49 00:02:16,649 --> 00:02:13,540 sure we got the ply orientation 50 00:02:19,140 --> 00:02:16,659 and ply cuts right they they have to be 51 00:02:23,009 --> 00:02:19,150 careful of the pie orientation there 52 00:02:27,059 --> 00:02:23,019 there's to make a better strength of the 53 00:02:30,839 --> 00:02:27,069 cone itself we lay some up at 0 degrees 54 00:02:33,599 --> 00:02:30,849 summit 45 degrees summit minus 45 55 00:02:36,270 --> 00:02:33,609 degrees in summit 90 degrees and we have 56 00:02:38,849 --> 00:02:36,280 a plan that the technicians and 57 00:02:40,619 --> 00:02:38,859 engineers follow through step-by-step to 58 00:02:42,330 --> 00:02:40,629 make that happen so it's all in the 59 00:02:44,009 --> 00:02:42,340 layering yeah well how much of this 60 00:02:47,369 --> 00:02:44,019 material do you use just to make one 61 00:02:50,839 --> 00:02:47,379 most go we actually use almost 300 feet 62 00:02:54,149 --> 00:02:50,849 almost the length of a football field to 63 00:02:56,819 --> 00:02:54,159 manufacture we have 18 plies in the main 64 00:03:00,149 --> 00:02:56,829 body of the cone and then there's six 65 00:03:03,030 --> 00:03:00,159 act replies in the very tip of the cone 66 00:03:05,909 --> 00:03:03,040 to make sure that there's X strength 67 00:03:08,610 --> 00:03:05,919 there when they mount the spike on in 68 00:03:10,530 --> 00:03:08,620 production alright Richards what happens 69 00:03:12,809 --> 00:03:10,540 after we've cut the pieces out here when 70 00:03:14,970 --> 00:03:12,819 we get done doing the cut out to the 71 00:03:16,559 --> 00:03:14,980 plies here of the pie-shaped we actually 72 00:03:22,319 --> 00:03:16,569 take it over to the cone we'll go over 73 00:03:25,140 --> 00:03:22,329 here and look and lay it lay the each 74 00:03:27,629 --> 00:03:25,150 fly up into the cone this is actually 75 00:03:30,149 --> 00:03:27,639 under vacuum right now and between each 76 00:03:31,920 --> 00:03:30,159 ply we have to put it under vacuum when 77 00:03:34,349 --> 00:03:31,930 we take it out of vacuum will lay this 78 00:03:37,349 --> 00:03:34,359 over and the operators come in here and 79 00:03:40,199 --> 00:03:37,359 do the layup from there it goes into the 80 00:03:45,240 --> 00:03:40,209 next room behind these doors here and it 81 00:03:47,759 --> 00:03:45,250 autoplay where it's pressure and held 82 00:03:50,670 --> 00:03:47,769 under vacuum and heated to 300 degrees 83 00:03:53,189 --> 00:03:50,680 to actually cure out the resonance in 84 00:03:54,869 --> 00:03:53,199 the pre impregnated material I know 85 00:03:57,360 --> 00:03:54,879 there's a few more steps after this and 86 00:03:58,890 --> 00:03:57,370 that's where Lori comes in I'm here with 87 00:04:00,449 --> 00:03:58,900 John sharp and he's the senior manager 88 00:04:01,979 --> 00:04:00,459 for Lockheed Martin for the external 89 00:04:05,280 --> 00:04:01,989 tank nose cone project here at Marshall 90 00:04:07,830 --> 00:04:05,290 and John we've seen it cut and cured now 91 00:04:10,140 --> 00:04:07,840 what happens after cure was taken into 92 00:04:11,699 --> 00:04:10,150 large oven mitts also here in the 93 00:04:14,369 --> 00:04:11,709 national center for advanced 94 00:04:16,680 --> 00:04:14,379 manufacturing and there is post cured 95 00:04:18,810 --> 00:04:16,690 that basically takes it up to a higher 96 00:04:20,999 --> 00:04:18,820 glass transition which makes it more 97 00:04:23,760 --> 00:04:21,009 thermally stable and this brought into 98 00:04:26,100 --> 00:04:23,770 this room where it's machine to be able 99 00:04:28,230 --> 00:04:26,110 to interface with the external tank 100 00:04:30,330 --> 00:04:28,240 that machine assembly facility in New 101 00:04:33,659 --> 00:04:30,340 Orleans so what you see in this room is 102 00:04:36,719 --> 00:04:33,669 a series of drilling and machining tools 103 00:04:39,719 --> 00:04:36,729 that the technicians and engineers used 104 00:04:41,790 --> 00:04:39,729 to put it into final form and to mount 105 00:04:44,339 --> 00:04:41,800 the brackets onto the base of the unit 106 00:04:47,790 --> 00:04:44,349 so that it interfaces with the external 107 00:04:49,200 --> 00:04:47,800 tank in final assembly in New Orleans so 108 00:04:52,170 --> 00:04:49,210 John I understand that each one has a 109 00:04:54,330 --> 00:04:52,180 name to the other do the production crew 110 00:04:56,749 --> 00:04:54,340 actually gives a nickname to each of the 111 00:04:59,700 --> 00:04:56,759 units and through the life the program 112 00:05:01,860 --> 00:04:59,710 will have built 54 of these units so 113 00:05:05,129 --> 00:05:01,870 each one has a name this particular one 114 00:05:07,379 --> 00:05:05,139 unit 52 is named Betsy any room for 115 00:05:09,029 --> 00:05:07,389 Laurie anywhere hey we'll see what we 116 00:05:14,219 --> 00:05:09,039 can do all right thanks for showing us 117 00:05:15,510 --> 00:05:14,229 around John we're in building 4705 at 118 00:05:17,369 --> 00:05:15,520 the Marshall Space Flight Center to talk 119 00:05:18,929 --> 00:05:17,379 to nature hatchet she is a mechanical 120 00:05:20,309 --> 00:05:18,939 engineer out here Marshall a nature 121 00:05:22,619 --> 00:05:20,319 first of all tell us what it is you do 122 00:05:25,559 --> 00:05:22,629 here okay I work for the mechanical 123 00:05:28,559 --> 00:05:25,569 fabrication branch asset ask lead for 124 00:05:31,320 --> 00:05:28,569 the machining development task all right 125 00:05:32,999 --> 00:05:31,330 and today we are here because of a huge 126 00:05:34,499 --> 00:05:33,009 project that you've been a part of the 127 00:05:36,600 --> 00:05:34,509 paint's not even dry in this brand new 128 00:05:38,369 --> 00:05:36,610 facility to look at this a brand-new 129 00:05:40,170 --> 00:05:38,379 machining tool this thing is immense 130 00:05:42,890 --> 00:05:40,180 what can you tell us about this what 131 00:05:46,469 --> 00:05:42,900 you're looking at is a high tolerance 132 00:05:49,589 --> 00:05:46,479 high-speed machining tool with seven 133 00:05:51,600 --> 00:05:49,599 axes and it's just awesome can you tell 134 00:05:53,070 --> 00:05:51,610 me what exactly machining means well 135 00:05:54,510 --> 00:05:53,080 what do you want to what will something 136 00:05:56,550 --> 00:05:54,520 happen when we put something in there to 137 00:05:58,589 --> 00:05:56,560 be machined it's a milling machine seven 138 00:06:01,230 --> 00:05:58,599 axis milling machine so what is going to 139 00:06:05,610 --> 00:06:01,240 do is pretty much take off small amounts 140 00:06:08,339 --> 00:06:05,620 of metallic or nonmetallic material and 141 00:06:10,439 --> 00:06:08,349 but it will do it at a high speed that's 142 00:06:12,390 --> 00:06:10,449 what makes it so special so something is 143 00:06:13,829 --> 00:06:12,400 being sculpted there right exactly what 144 00:06:17,249 --> 00:06:13,839 do you mean when you say seven access 145 00:06:19,350 --> 00:06:17,259 though o 7 x's this machine has seven 146 00:06:21,749 --> 00:06:19,360 axis which means that it just can move 147 00:06:24,629 --> 00:06:21,759 in seven different directions there's 148 00:06:26,219 --> 00:06:24,639 the motion so you have if you look at 149 00:06:29,390 --> 00:06:26,229 the red component there that's the 150 00:06:33,019 --> 00:06:29,400 spindle there's five axis on the spindle 151 00:06:37,690 --> 00:06:33,029 you have the rotary table right here the 152 00:06:40,190 --> 00:06:37,700 turntable there is one axis 153 00:06:43,780 --> 00:06:40,200 then you have the headstock in the tail 154 00:06:46,700 --> 00:06:43,790 sockets it has the indexers there is one 155 00:06:49,100 --> 00:06:46,710 axis there so if you count them all up 156 00:06:50,750 --> 00:06:49,110 you have seven axes that's impressive 157 00:06:52,640 --> 00:06:50,760 what kind of things will we expect to be 158 00:06:56,810 --> 00:06:52,650 seeing on here oh yeah we're going to 159 00:06:58,400 --> 00:06:56,820 fabricate dome shape components starting 160 00:07:01,670 --> 00:06:58,410 with the common Boca demonstration 161 00:07:05,150 --> 00:07:01,680 articles we we're capable of putting 162 00:07:10,130 --> 00:07:05,160 cylindrical components between the 163 00:07:11,300 --> 00:07:10,140 trunnions for cylindrical machining so I 164 00:07:14,630 --> 00:07:11,310 can be turned in many different ways 165 00:07:16,970 --> 00:07:14,640 right it's basically like a rotisserie i 166 00:07:18,380 --> 00:07:16,980 guess if if you think about it yet giant 167 00:07:20,600 --> 00:07:18,390 rotisserie that could make it end up in 168 00:07:21,710 --> 00:07:20,610 space ok well thanks very much we look 169 00:07:24,409 --> 00:07:21,720 forward to seeing the first element you 170 00:07:26,810 --> 00:07:24,419 put on there thank you Bill it would be 171 00:07:28,909 --> 00:07:26,820 so cool to have my name on a nose cone I 172 00:07:30,890 --> 00:07:28,919 agree but you know to be even cooler the 173 00:07:33,200 --> 00:07:30,900 size of the cupcake you could bake in 174 00:07:35,150 --> 00:07:33,210 this thing always thinking with his 175 00:07:47,660 --> 00:07:35,160 stomach find out where we turn up next
