I certainly agree with the theme of this thread.
As it happens I try to encourage 6th formers to study for a career in the aerospace business and I tell them that in my view the first stage turbine blades in the hot end of a Trent or similiar are in my view the pinnacle of the mechanical engineers achievements to date.
I explain to them that each small credit card sized blade extracts from the airflow about three time the horsepower of a Formula 1 engine. It is also going round at a speed that means the force making it try to fly off would support the weight of a couple of double decker buses. It also happens to be operating in a gas stream that is several hundred degrees centigrade above its melting point. A good trick.
We should be very proud that R-R really is a world class company and does a great deal to keep P&W and GE honest.
