A jet engine afterburner is an extended exhaust section containing extra fuel injectors. Since the jet engine upstream (i.e., before the turbine) will use little of the oxygen it ingests, additional fuel can be burned after the gas flow has left the turbines. When the afterburner is turned on, fuel is injected and igniters are fired.

The J40-8 was only a little over 40 inches (1,000 mm) in diameter but 25 feet (7.6 m) long, with accessories and including the afterburner. It weighed almost 3,500 pounds (1,600 kg), the -6 being almost 7 feet (2.1 m) shorter and about 600 pounds (270 kg) lighter, because it did not have an afterburner.
The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
An unusual addition to the R-25 was an emergency mode thrust boost which increased the compressor speed to 106% and also increased the afterburner fuel flow with the addition of a second afterburner fuel pump. Thrust was increased to 96.5 kilonewtons (21,700 lb f) below an altitude of 2,000 metres (6,600 ft). The time limit for its use was 1 ...
The R7 driver has been one of the most popular drivers in golf because of its ability to reduce the effects of faults. With the success of the R7 Quad, some other companies have sought to bring customizable products to the market, while others have produced clubs that are pre-weighted for the same corrective ball-flight.
The engine's 12-stage compressor was driven by two turbine stages on a single shaft. Early development engines included a simple "eyelid" afterburner, actuated by control rods that ran the length of the engine. By the time the engine reached production, the rear nozzle had an iris-type "petal" design.
These parameters are published in specification sheets by driver manufacturers so that designers have a guide in selecting off-the-shelf drivers for loudspeaker designs. Using these parameters, a loudspeaker designer may simulate the position, velocity and acceleration of the diaphragm, the input impedance and the sound output of a system ...
