1 00:00:00,000 --> 00:00:00,000 2 00:00:03,740 --> 00:00:09,620 We 3 00:00:09,620 --> 00:00:11,842 are at Edwards Air Force Base on Cattle 4 00:00:11,842 --> 00:00:13,731 King currently , and we are in an 5 00:00:13,731 --> 00:00:16,220 underground location . Our test article 6 00:00:16,220 --> 00:00:20,210 is located about 50 yards from us on a 7 00:00:20,220 --> 00:00:22,442 horizontal thrust , and today we're out 8 00:00:22,442 --> 00:00:26,070 here testing a T 38 looking at various 9 00:00:26,070 --> 00:00:29,870 parameters such as nozzle position , E 10 00:00:29,870 --> 00:00:32,240 G , temperature , trust and throttle 11 00:00:32,240 --> 00:00:34,570 position . Part of the editors Legacy 12 00:00:34,570 --> 00:00:37,130 was built in 1955 same age as 13 00:00:37,140 --> 00:00:40,420 Disneyland . It's the only known Free 14 00:00:40,420 --> 00:00:42,850 World Thrusts band of its nature . 15 00:00:43,940 --> 00:00:47,060 It is a roll on roll off facility 16 00:00:47,740 --> 00:00:51,410 Cessna two C five . We only deal with 17 00:00:51,410 --> 00:00:53,466 thrust numbers . We do not deal with 18 00:00:53,466 --> 00:00:55,790 aircraft data parameters . 19 00:00:55,860 --> 00:00:59,790 They're kind of like 20 00:00:59,800 --> 00:01:02,350 boots on your feet . The aircraft's not 21 00:01:02,350 --> 00:01:04,650 going anywhere . Those were built as 22 00:01:04,650 --> 00:01:07,100 part of an F 18 program for us many 23 00:01:07,100 --> 00:01:10,100 years ago . Any fighter type aircraft 24 00:01:10,110 --> 00:01:13,470 tricycle configuration . It's not going 25 00:01:13,470 --> 00:01:17,440 anywhere . What 26 00:01:17,440 --> 00:01:19,496 you're looking at right now , on the 27 00:01:19,496 --> 00:01:22,370 right side are the power supplies for 28 00:01:22,370 --> 00:01:25,520 the load cell . Up high in the center 29 00:01:25,520 --> 00:01:29,030 is a monitor . Lower is 30 00:01:29,040 --> 00:01:32,700 the data acquisition software screen on 31 00:01:32,700 --> 00:01:35,300 the left side , R D M s one for each 32 00:01:35,300 --> 00:01:38,320 load cell . We bring the millet bolts 33 00:01:38,320 --> 00:01:41,640 from each load cell into the D . M s 34 00:01:41,640 --> 00:01:44,650 that's transferred to the software that 35 00:01:44,660 --> 00:01:46,827 Millersville reading is then converted 36 00:01:46,827 --> 00:01:49,660 £2 based on a calibration slow 37 00:01:51,880 --> 00:01:55,670 today rewarding aspect is training 38 00:01:55,670 --> 00:01:57,559 other people to carry on for me . 39 00:01:57,640 --> 00:02:01,580 Yeah . 40 00:02:01,590 --> 00:02:04,290 So this is This is great . Honestly , 41 00:02:04,380 --> 00:02:06,750 it's given us Roth Ross data that we 42 00:02:06,750 --> 00:02:09,300 could not collect otherwise without a 43 00:02:09,300 --> 00:02:11,300 good a good engine model and a good 44 00:02:11,300 --> 00:02:13,790 drag model , both of which are just 45 00:02:13,790 --> 00:02:16,012 models . Anyway , so to actually coming 46 00:02:16,012 --> 00:02:19,340 out and being able to gather empirical 47 00:02:19,340 --> 00:02:22,580 data , that gives us a no kidding . Hey , 48 00:02:22,580 --> 00:02:24,691 did this change ? How much thrust did 49 00:02:24,691 --> 00:02:26,913 we lose ? Uh , is there a difference in 50 00:02:26,913 --> 00:02:28,802 thrust between the left and right 51 00:02:28,802 --> 00:02:30,969 engines ? Uh , it's it's critical . We 52 00:02:30,969 --> 00:02:33,191 definitely couldn't do this part of the 53 00:02:33,191 --> 00:02:35,469 test plan without a facility like this . 54 00:02:38,340 --> 00:02:41,050 Yeah , no , it's it's very cool . I 55 00:02:41,060 --> 00:02:43,171 think you could say that about nearly 56 00:02:43,171 --> 00:02:45,480 almost any building here on Edwards . A 57 00:02:45,490 --> 00:02:47,768 lot of history , a lot of flight tests , 58 00:02:47,768 --> 00:02:50,080 history . Um , just the names that you 59 00:02:50,080 --> 00:02:52,200 hear people that have been walking , 60 00:02:52,210 --> 00:02:54,210 walking these streets , walking the 61 00:02:54,210 --> 00:02:56,432 hallways . Uh , it really is humbling . 62 00:02:56,432 --> 00:02:58,599 Um , to an extent of just , you know , 63 00:02:58,599 --> 00:03:00,543 it's crazy to think that it's been 64 00:03:00,543 --> 00:03:02,490 around since the fifties and we're 65 00:03:02,490 --> 00:03:04,712 still using it today and the aircraft's 66 00:03:04,712 --> 00:03:06,879 been around just as long . But here we 67 00:03:06,879 --> 00:03:08,620 are in 2021 testing . You know 68 00:03:08,620 --> 00:03:10,810 something new , something exciting for 69 00:03:10,810 --> 00:03:13,550 us at least and getting to use 70 00:03:13,830 --> 00:03:15,663 something that I'm sure people's 71 00:03:15,663 --> 00:03:17,700 grandfathers have been using . It's 72 00:03:17,700 --> 00:03:19,610 pretty cool , pretty unique .
