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.
Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...
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.
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 maximum thrust was 7,500 kilograms force (73.5 kN, 16,500 lbf) dry and 11,200 kilograms force (110 kN, 24,700 lbf) with afterburner. This thrust enabled the Mikoyan-Gurevich MiG-25, with two engines, to reach Mach 3.2, although the engines had to be scrapped after a flight to Mach 3.2. The engine had a very high fuel consumption, especially ...
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.
Most explinations state that the afterburner heats the exhaust gasses and increases thrust by virture of the increased exhaust velocity. The exhaust velocity does increase but no mention is given to how or where the rapidly expanding gasses act on the engine to transfer the additional thrust to the engine and airframe.
