Jet air modern combat

A Royal Australian Air Force (RAAF) EA-18G Growler electronic warfare aircraft is being reported as damaged in an incident that occurred at 10:45 AM local time on Jan. 27 at Nellis AFB, outside Las Vegas, Nevada, according to a statement issued by Nellis AFB and quoted in the Sydney Morning Herald.

The aircraft, one of a contingent of four Australian EF-18G Growlers at Nellis AFB for the Red Flag 18-1 air combat exercise, is part of the 340-person contingent of the Royal Australian Air Force participating in this year’s first Red Flag Exercise.

Red Flag is a large-scale, highly realistic air combat exercise originating from Nellis AFB and taking place over the large air combat training ranges that surround the area.

A jet engine is a type of reaction engine discharging a fast-moving jet that generates thrust by jet propulsion . This broad definition includes airbreathing jet engines ( turbojets , turbofans , ramjets , and pulse jets ). In general, jet engines are combustion engines.

The thrust of a typical jetliner engine went from 5,000 lbf (22,000 N) ( de Havilland Ghost turbojet ) in the 1950s to 115,000 lbf (510,000 N) ( General Electric GE90 turbofan) in the 1990s, and their reliability went from 40 in-flight shutdowns per 100,000 engine flight hours to less than one in the late 1990s. This, combined with greatly decreased fuel consumption, permitted routine transatlantic flight by twin-engined airliners by the turn of the century, where before a similar journey would have required multiple fuel stops.

Jet engines date back to the invention of the aeolipile before the first century AD. This device directed steam power through two nozzles to cause a sphere to spin rapidly on its axis. So far as is known, it did not supply mechanical power and the potential practical applications of this invention did not receive recognition. Instead, it was seen as a curiosity.
