Introduction to the Regimes of Flight
You already know a great deal about traveling at different speeds. You can move slowly and go a long way. You can move fast and get places faster, but you get tired because it takes more energy.
If you ride your bike, skateboard or rollerblade, you can travel even faster, but it requires skill and you trade off a little safety in return.
These are the same kinds of questions engineers and scientists study when they design planes. They must choose between stability and speed and ways of reducing friction and overcoming gravity.
Here you will learn about flight at low, medium, high, supersonic and hypersonic speeds.
You will be able to try lessons, experiments, and enter contests. You can also talk to engineers and scientists who have worked on different airplanes and ask them about what they learned.
