1 00:00:00,000 --> 00:00:04,000 I did some research on hovercraft to prepare for the design process. 2 00:00:04,000 --> 00:00:05,000 What did you find out? 3 00:00:05,000 --> 00:00:11,000 I discovered that the Navy has used hovercraft to transport up to 60 tons of cargo over both land and water. 4 00:00:11,000 --> 00:00:14,000 Wow! There are 2,000 pounds in a ton. 5 00:00:14,000 --> 00:00:18,000 That is more than 120,000 pounds. 6 00:00:18,000 --> 00:00:19,000 Very good. 7 00:00:19,000 --> 00:00:23,000 They can go up to speeds of 46 miles per hour with a full load. 8 00:00:23,000 --> 00:00:26,000 This requires engines with 16,000 horsepower. 9 00:00:26,000 --> 00:00:28,000 That's a lot of horses. 10 00:00:28,000 --> 00:00:30,000 I also did some research on air pressure. 11 00:00:30,000 --> 00:00:34,000 I needed to discover how powerful a blower I would need for an air supply 12 00:00:34,000 --> 00:00:36,000 and how big the craft would have to be to support my weight. 13 00:00:36,000 --> 00:00:39,000 It's what you need to know, just like the problem board. 14 00:00:39,000 --> 00:00:40,000 Precisely. 15 00:00:40,000 --> 00:00:46,000 I also found I needed to build a model of my hovercraft and test it to find the answers to all of my questions. 16 00:00:46,000 --> 00:00:53,000 I'm probably going to have to test and retest to refine my model before I actually build my prototype hovercraft. 17 00:00:53,000 --> 00:00:54,000 Can we help? 18 00:00:54,000 --> 00:00:58,000 Sure. Let's take a look at my first model. 19 00:00:58,000 --> 00:01:02,000 Based upon my research, I chose a round design covered in plastic. 20 00:01:02,000 --> 00:01:04,000 My research indicates I need a leaf bed.
