ENGINEERING ATOMS INSIDE THE JET ENGINE

Inside a jet engine is one of the most extreme environments known to engineering.

In less than a second, a tonne of air is sucked into the engine, squeezed to a fraction of its normal volume and then passed across hundreds of blades rotating at speeds of up to 10,000 rpm; reaching the combustor, the air is mixed with kerosene and ignited; the resulting gases are about a third as hot as the sun’s surface and hurtle at speeds of almost 1,500 km per hour towards a wall of turbines, where each blade generates power equivalent to the thrust of a Formula One racing car

Designing crack-resistant metals

Discoveries about the causes of stress-corrosion cracking in metal alloys could help prevent failure of critical infrastructure systems such as pipelines that transport water, fossil fuels and natural gas, as well as operating systems for nuclear power generation facilities and the framework of aircraft. 150624182434_1_540x360
