Many readers will be familiar with the Dyson Air Multiplier, an ingenious bladeless fan design in which a compressor pushes jets of air from the inside edge of a large ring. This fast-moving air draws ...

A modern jet engine is a complex mechanical wonder. However, these aren't engines that will just roar into action with the turn of a key or the press of a button. Often, turbine engines will need ...

Aero engines are among the most complex machines in the world, and the indigenous development of one would have implications ...

DARPA has awarded a contract to Aurora Flight Sciences to build a full-scale aircraft called the X-65. It will test a new technology that replaces moving control surfaces with Active Flow Control (AFC ...

It'll fly instead using Active Flow Control (AFC), using a series of nozzle arrays along the wings connected to a pressurized air system, capable of blowing controlled bursts of air that can directly ...

The search for new solutions for engine ignition systems and combustion of lean air-gas mixtures has led to the application of a two-stage combustion system, previously also known as turbulent jet ...
