As more people want to fly each year, it is important to make "flying things" work better. A great way to do this is to make the "fire" which keeps them in the air burn hotter. With a hotter fire, we need less stuff for burning and we can save money. However, a hotter fire also means that stuff around it might become hotter than it should, which is a big problem. My work is coming up with new types of stuff to be used in the area close to the fire. First, I use big computers to get an idea of what kind of new stuff might work well. Second, with help from some friends, I make it. Third, I use new ways of checking how good this stuff really is by making it hot and then pulling it until it breaks. Last, I talk to other people and hope they will use this new stuff inside their "flying things" soon.
