A-level Physics courswork help? Which material?

[Rusty Cessna]

Hi there all,

For my A-level Physics course, over the half term I have been tasked with finding a material, any of my choice that I have to research and find out about, and them do a presentation on.

Now naturally I want to do something aviation related but I honestly don't know where to start.

I was thinking of Propeller materials or something in the engines. Could any of you bright sparks give me some ideas and if so how do I go about researching this??

All help and any ideas greatly appreciated.

Thanks
Rusty
