Descargar la transcripción

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