An Analytical Method for Estimating the Performance of a Gas Turbine Engine with Water-Methanol Injection 700208

This paper presents an analytical method for the prediction of gas turbine engine performance augmented by water-methanol injection into the compressor, the combustor, or a combination of these injection points. Thus far, the basic method has been successfully applied to estimates of the augmented performance of a single-spool turboprop engine. However, it is general enough that it may be adapted to any type of gas turbine engine, including multispool turbojet, turbofan, and turboshaft engines. In addition to a description of the basic method itself, a comparison of tested and analytical results is included in support of the procedures and conclusions involved.
