L.p. Compressors

Picture of L.p. Compressors

Jet engines and other gas turbine engines are often uprated by adding a zero-stage, sometimes written '0' stage,

At a given core size, adding a stage to the front of the compressor not only increases the cycle overall pressure ratio, but increases the core mass flow. A further uprating may be done by adding another stage in front of the previously-added zero stage, in which case the new one may be known as a zero-zero stage.

A comparison with other ways of uprating an existing engine without drastically redesigning the engine shows for a particular case, eg the Rolls-Royce/SNECMA M45H, the thrust could have been increased by 25% with a zero-staged l-p compressor or 10% with either an improved HP turbine or with water injection.

Zero-staging is also combined with other modifications to provide increased thrust or lower turbine temperature. It may be required for an existing aircraft weight increase, or for a new application, as shown by the following examples.

A 15-stage Rolls-Royce Avon powered the Lightning F.1. A zero-stage, together with a new turbine, was added (total 16 stages) for the Caravelle III. A zero-zero stage was added (total 17 stages) for the Caravelle VI.
