Lesson plan
Zero stage
A zero stage, sometimes written '0' stage, is an additional compressor stage added to the front of jet engines and other gas turbine engines to increase their performance. This addition serves to enhance engine efficiency by increasing both the cycle overall pressure ratio and the core mass flow, without altering the engine's core dimensions. In cases where further performance enhancement is required, a subsequent stage may be added in front of the initial zero stage, designated as a zero–zero stage. This technique, zero-staging, is often utilized in conjunction with other engine modifications to achieve higher thrust or reduce turbine operating temperatures. This is particularly relevant when adapting engines for increased aircraft weight or novel applications. For example, in situations where an aircraft's design is modified to accommodate heavier loads, zero-staging can provide the necessary thrust augmentation without necessitating a complete engine replacement, offering a more efficient and cost-effective upgrade.
