Ex Rolls-Royce employee talks jet engines!
Do you know why every jet engine has a rubber tip? Neither did I.
My speech will be aimed at a regular curious person. No hardcore engineering details, just fun stuff: * How does it work? * Why does it look like this? * What is it's speed/height limit? * How do we start it? * And other interesting somewhat technical details
Next time people fly, I hope they'll say: "Do you know we breathe air that comes from the jet engine?!"
P.s.: Information will be based on my experience at the company, university material and personal interests
