I'll agree with Ghengis that is one huge topic. I fear you may swamp yourselves.
Personally, I'd suggest you don't do the specific things like failure cases and troubleshooting because that is extremely dependent on the aircraft. Unless that is the required topic, in which case you should focus just on that, for selected types, and not try to cover everything.
My suggestion would be to focus on the history of the development of flaps and slats - the different types, and why each was introduced. That allows you to, at each stage a new idea came along to explain why it did so, which allows you to then address the aerodynamic or structural aspects as they are relevant.
Otherwise what you are proposing is very ambitious and, I fear, may be unachieveable for you.
