The site has four different animations that explain how the different types of engines work: turbofans, rocket engine, turboprop and land based turbine engine (generates electricity).
The animations are well done and explain the concepts in a way that all students can understand.
This is a great resource for science classes and could also be used in other classes to get students interested about these topics.
Note: I worked for Pratt & Whitney many years ago in my previous life as a Aerospace Engineer.
