Optimization of the part load performance of various gas turbine engine schemes.

Many works on gas turbine engines contain much information concerning the performance of various engine schemes both in simpler and in more complicated forms. Such information enables the design performance to be estimated, but there appears to have been very little works on the optimum performance under non-design conditions. In this paper, we attempt to include a comparison of part load performance characteristics and to optimize them. The multiplier method is adopted as an optimization procedure. As a result of this work, it is possible to indicate the optimization technique by which the comparable part load performance of different gas turbine schemes may be assessed.
