low-pressure compressor

It had a seven-stage low-pressure compressor, the first six stages made of aluminium and the last of titanium.

The low-pressure compressor now had six stages, and the high-pressure nine, driven by two and one stage turbines respectively.

In order to increase the thrust of the engine, the fan was increased with one stage at the cost of one low-pressure compressor stage.

The major changes are a larger fan, a fifth low-pressure turbine stage, and the same four-stage low-pressure compressor found in the -5B variant.

The engine has a wide-chord swept fan, two-stage low-pressure compressor and counter rotating high-pressure compressor based on a titanium impeller.

Aerodynamic improvements such as an updated fan, low-pressure compressor, high-pressure compressor and combustor make this variant 10-11% more fuel efficient than its predecessors.

They decided that the only reasonable solution to low compressor efficiency was to use what would today be referred to as a "two-spool" design, with separate high and low-pressure compressors.

The low-pressure compressor was encased in a two-part cylindrical casing with stiffening ribs, which gave it an odd appearance similar to the bottom of an egg carton.

The new engine differed from the RCo.8 in having a new "zeroth stage" at the front of the low-pressure compressor, further increasing cold airflow around the engine.

The designs were advanced for the era, typically featuring a "two-spool" layout with high- and low-pressure compressors that individually had more stages than typical engines of the era.

The new version had a four stage low-pressure compressor driven by a two-stage turbine, and an eight stage high-pressure compressor driven by another two-stage turbine.

The booster is also commonly called the "low-pressure compressor" (LPC) as it sits on the low-pressure shaft and compresses the flow initially before reaching the high-pressure compressor.

Using the core of the Kaveri engine, GTRE added low-pressure compressor and turbine as a gas generator and designed a free power turbine to generate shaft power for maritime applications.

Nitrox mixtures, containing between 24% and 40% oxygen (O), are then delivered to a high-pressure compressor to fill scuba cylinders or storage tanks, or to a low-pressure compressor for pumping to surface-supply divers.

Among the changes from the CFM56-5A is the option of a double-annular combustor that reduces emissions (particularly NO), a new fan in a longer fan case, and a new low-pressure compressor with a fourth stage (up from three in earlier variants).
