1 00:00:00,936 --> 00:00:02,736 At NASA Glenn we're currently working 2 00:00:02,906 --> 00:00:05,336 on investigating ceramic matrix composites. 3 00:00:05,826 --> 00:00:07,936 The reason we're interested in this material system is 4 00:00:07,976 --> 00:00:09,826 because they offer a variety of benefits 5 00:00:09,856 --> 00:00:12,606 over current materials used in aircraft engines today. 6 00:00:13,186 --> 00:00:14,736 Ceramics compared with metals, 7 00:00:15,266 --> 00:00:17,756 actually can handle much higher operating temperatures 8 00:00:17,986 --> 00:00:18,766 and are lighter. 9 00:00:19,296 --> 00:00:21,786 As a result by replacing current metal-based parts 10 00:00:21,836 --> 00:00:23,536 in aircraft engines, we hope 11 00:00:23,536 --> 00:00:26,726 that by applying ceramic matrix composites we'll get better fuel 12 00:00:26,726 --> 00:00:30,916 economy and efficiency in future generations of aircraft engines. 13 00:00:31,546 --> 00:00:34,576 NASA is pushing the extremes of this particular material 14 00:00:35,036 --> 00:00:37,506 by evaluating ceramic matrix composites 15 00:00:37,556 --> 00:00:40,406 for the mechanical properties as well as their temperature 16 00:00:40,406 --> 00:00:42,286 and thermal properties to ensure 17 00:00:42,286 --> 00:00:44,376 that these materials will be safe as well 18 00:00:44,376 --> 00:00:47,546 as offer significant benefits over current metal-based parts 19 00:00:47,716 --> 00:00:48,926 that are commonly used today. 20 00:00:49,226 --> 00:00:50,446 Currently we are working 21 00:00:50,446 --> 00:00:52,926 on 3D printing ceramic matrix composites. 22 00:00:53,286 --> 00:00:56,086 With 3D printing we can actually attain a variety 23 00:00:56,086 --> 00:00:59,536 of geometries more quickly as well as more economically 24 00:00:59,586 --> 00:01:01,466 than conventional processing methods. 25 00:01:02,296 --> 00:01:05,046 From 3D printing we can actually take a part prepared 26 00:01:05,406 --> 00:01:07,616 and then evaluate it using a burner rig. 27 00:01:07,826 --> 00:01:11,836 It allows us to evaluate a more realistic environment seen 28 00:01:11,936 --> 00:01:13,516 in an aircraft engine. 29 00:01:14,006 --> 00:01:16,596 With the burner rig we can actually flow through jet fuel 30 00:01:16,596 --> 00:01:18,976 that we can ignite and achieve temperatures 31 00:01:18,976 --> 00:01:21,186 of to 2700 degrees Fahrenheit 32 00:01:21,506 --> 00:01:24,616 that we can subject different parts including ceramics to,
