bypass duct

The bypass duct runs the full length the engine.

Beyond this, the flow is then reversed 180 deg again to exit in the fan bypass duct.

A lined bypass duct has a lower pressure loss, due to the streamlining effect of the inner wall introduced.

Best guess ran to a rag that may have been wedged between the bypass ducts, accounting for its fiery state.

The engine is designed to pass ingested debris away from the core and into the bypass duct where it can exit harmlessly.

The engine pods were also modified with a reduction in diameter and the elimination of the -50 and -61 bypass duct.

Bypass ducts may be fitted with doors that allow the air to be diverted forward, providing "reverse thrust".

During low speed flight, controllable flaps close the bypass duct and force air directly into the compressor section of the turbojet.

If the turbofan is unmixed, the bypass duct will terminate at the bypass nozzle.

A coolant control valve is mounted on the combustion chamber coolant bypass duct of each engine.

Bypass ducts deliver the flow from the fan with minimum losses to the bypass propelling nozzle.

Any flow surplus to that demanded by the HP compressor passes through the blow-off valve into the bypass duct.

The majority of the bird remains were directed through the bypass duct of the engine after passing through the low-pressure compressor.

It was mounted in the oxidizer turbine bypass duct and equipped with a nozzle, the size of which was determined during engine calibration.

A small proportion of the bypass duct air entered the IP compressor, via a special diverter valve, to sustain the gas generator.

A bypass duct is an annular passage that allows some of a turbofan's airflow to bypass the engine core, or gas generator.

They work by actuating a door that pivots down into the bypass duct, both blocking the bypass air and deflecting the flow outward, creating the reverse thrust.

In mixed turbofans, the bypass duct leads to the cold chute of a forced mixer or cold mixer of an annular mixer.

As a result, such materials go through the relatively unobstructed bypass duct, rather than through the core of the engine, which contains the smaller and more delicate compressor blades.

The low pressure compressor(LPC), usually known as a fan, compresses air into a bypass duct whilst its inner portion supercharges the core compressor.

After the Fan Outer compression calculation, there is a Bypass Duct pressure loss/Bypass Nozzle expansion calculation.

The active clearance control consists of the ACC valve which mixes hot and cold air from the compressor exit and the bypass duct, respectively, to a desired temperature.

In reverse thrust, intake air entered the bypass duct, via a gap in the cold nozzle outer wall, and went through the fan, to be expelled through the intake.

This engine had a slightly different configuration with a long bypass duct and mixed exhaust flow, rather than a short bypass duct with unmixed exhaust flow.

The ram rise in the intake is negligible, so the cold nozzle pressure ratio is not even as high as the fan pressure ratio because of the bypass duct pressure loss.
