A Chinese team has demonstrated a prototype of a microwave plasma thruster capable of working in the Earth's atmosphere and producing thrust with an efficiency comparable to the jet engines you'd find ...

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 ...

SAE International Journal of Engines, Vol. 4, No. 2 (2011), pp. 2405-2417 (13 pages) ABSTRACT In order to increase the efficiency of automotive turbochargers at low speed without compromising the ...

FORGET fuel-powered jet engines. We’re on the verge of having aircraft that can fly from the ground up to the edge of space using air and electricity alone. Traditional jet engines create thrust by ...

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 ...
