WEBVTT 1 00:00:00.497 --> 00:00:03.080 (upbeat music) 2 00:00:09.831 --> 00:00:13.746 line:15% When I was a kid, I got lost at this park called Legoland. 3 00:00:13.746 --> 00:00:16.218 line:15% And I was running around, I was really excited. 4 00:00:16.218 --> 00:00:17.477 line:15% And luckily, I was found 5 00:00:17.477 --> 00:00:19.650 but if it was a bigger park, such as Disney World, 6 00:00:19.650 --> 00:00:22.676 that can be a pressing issue, a very scary issue. 7 00:00:22.676 --> 00:00:24.224 So what if we were in a scary situation? 8 00:00:24.224 --> 00:00:25.382 Let's say I'm military personnel 9 00:00:25.382 --> 00:00:27.115 and I'm trying to find one of my friends 10 00:00:27.115 --> 00:00:28.738 in a very hostile environment. 11 00:00:28.738 --> 00:00:31.531 Sometimes it's not easy to just call the drone 12 00:00:31.531 --> 00:00:33.164 and say, "Hey, we need to find this person." 13 00:00:33.164 --> 00:00:35.250 I need something quick, quiet and stealthy 14 00:00:35.250 --> 00:00:36.939 that's gonna be able to find somebody. 15 00:00:36.939 --> 00:00:39.502 Or even something a little more relatable to Mississippi. 16 00:00:39.502 --> 00:00:40.845 If I'm dealing with... 17 00:00:40.845 --> 00:00:41.818 Let's say I'm a game warden 18 00:00:41.818 --> 00:00:43.630 and I have a very large amount of land 19 00:00:43.630 --> 00:00:47.002 and I'm renting it out to certain people who wanna hunt, 20 00:00:47.002 --> 00:00:48.607 I need to make sure they're not doing this illegally 21 00:00:48.607 --> 00:00:50.334 during certain parts of the year. 22 00:00:50.334 --> 00:00:53.706 And so I need something that can not only locate my animals 23 00:00:53.706 --> 00:00:55.897 and my people and my crops to make sure that no one's 24 00:00:55.897 --> 00:00:58.761 going through and hunting them and picking my stuff around. 25 00:00:58.761 --> 00:01:00.760 I need to also be able to detect the people 26 00:01:00.760 --> 00:01:03.781 and find them without giving away my own location. 27 00:01:03.781 --> 00:01:06.413 Current drones and UAV's can't really do that as effectively 28 00:01:06.413 --> 00:01:08.298 and quad rotors are a little bit too noisy, 29 00:01:08.298 --> 00:01:10.917 and they can be easily disturbed with gusts of wind. 30 00:01:10.917 --> 00:01:12.877 But if you look into nature, 31 00:01:12.877 --> 00:01:16.969 owls have mastered this capability to fly silently 32 00:01:16.969 --> 00:01:20.797 and stealthily and still be able to maintain slow speeds. 33 00:01:20.797 --> 00:01:23.462 And this is basically because of the leading-edge serrations 34 00:01:23.462 --> 00:01:25.269 that are on the very front of the wing. 35 00:01:25.269 --> 00:01:28.311 So this barn owl, as it glides over these feathers, 36 00:01:28.311 --> 00:01:30.235 they're completely undisturbed. 37 00:01:30.235 --> 00:01:33.127 And that's because as air flows over the serrations, 38 00:01:33.127 --> 00:01:35.442 it creates a laminar separation bubble 39 00:01:35.442 --> 00:01:36.610 and then down and from the back 40 00:01:36.610 --> 00:01:38.408 and the velvet-like surface of the feathers 41 00:01:38.408 --> 00:01:40.880 completely levels out all noise, 42 00:01:40.880 --> 00:01:43.579 and it still can fly slowly. 43 00:01:43.579 --> 00:01:46.688 My research is using the first order of proximation 44 00:01:46.688 --> 00:01:49.563 to mimic the length, the tilt angle, 45 00:01:49.563 --> 00:01:52.566 and the inclination angle of these serrations 46 00:01:52.566 --> 00:01:55.750 and utilizing them in a 3D printing program. 47 00:01:55.750 --> 00:01:57.918 Once these serrations are 3D printed, 48 00:01:57.918 --> 00:02:01.861 they'll be mimicked and laid over into a silicone molding. 49 00:02:01.861 --> 00:02:03.775 The silicone molding will then... 50 00:02:03.775 --> 00:02:05.943 The silicone serrations will then be placed on 51 00:02:05.943 --> 00:02:08.988 the very front of a wing, or UAV ring 52 00:02:08.988 --> 00:02:10.441 that is also laid over 53 00:02:10.441 --> 00:02:12.439 with some type of a velvet-like surface 54 00:02:12.439 --> 00:02:14.153 that can mimic the skin roughness, 55 00:02:14.153 --> 00:02:17.583 the surface roughness, if you will, of this actual owl. 56 00:02:17.583 --> 00:02:20.344 After that, flight testing will be done to make sure 57 00:02:20.344 --> 00:02:23.445 that it can look exactly, or fly just as efficiently 58 00:02:23.445 --> 00:02:24.945 as a barn owl can. 59 00:02:26.093 --> 00:02:28.009 Using this type of technology, 60 00:02:28.009 --> 00:02:29.238 a barn owl will not only... 61 00:02:29.238 --> 00:02:31.151 This barn owl inspired UAV 62 00:02:31.151 --> 00:02:34.097 will not only be able to fly stealthily and quietly 63 00:02:34.097 --> 00:02:38.620 while maintaining its same type of aerodynamic efficiency, 64 00:02:38.620 --> 00:02:40.839 it can be able to utilize the help of a farmer, 65 00:02:40.839 --> 00:02:42.920 trying to make sure no one's in his own area 66 00:02:42.920 --> 00:02:46.929 or try to help military personnel in a hostile environment, 67 00:02:46.929 --> 00:02:49.325 or just simply save that one kid who ran away 68 00:02:49.325 --> 00:02:51.498 outside of Disney World, looking for Mickey Mouse. 69 00:02:51.498 --> 00:02:52.425 Thank you. 70 00:02:52.425 --> 00:02:55.008 (upbeat music)
