afterburner |
Also found in: Dictionary/thesaurus, Wikipedia | 0.06 sec. |
afterburnerSecond combustion chamber in a turbojet or turbofan engine, immediately in front of the engine's exhaust nozzle. The injection and combustion of extra fuel in this chamber provide additional thrust for takeoff or supersonic flight; in most cases, the afterburner can nearly double the thrust of a turbojet engine. The jet nozzle must be larger when using the afterburner, so an automatic, adjustable nozzle is an essential component of the afterburner system. Because the afterburner sharply increases fuel consumption and is generally less effective at subsonic speeds, its use is usually restricted to supersonic military aircraft. |

And unlike the F-22, it is not capable of supercruise--supersonic flight
without the highly inefficient use of afterburners. Teets said the new system can calculate state vectors for where
strategic missiles are going, will look into a theater battlespace and
identify when short-range ballistic missiles are launched, will pick up
scud missile launches, and can identify fighter aircraft when they turn
on their afterburners. A line of gas fired afterburners, designed to protect the
environment by reducing the amount of VOCs and/or smoke released into
the atmosphere, is available from the company. |
