PART POWER MODELING OF GAS TURBINE ENGINE SYSTEMS

摘要

A method is developed tor modeling the part power operation of the two-spool gas turbine engine using the simple and regenerative cycles. The approach is to replace the compressor map with a simple functional relation between the cycle pressure ratio and the peak temperature based on obtaining a reasonable operating line. In this way. the part power characteristics can be developed for cycles whose design parameters are varied. For engine systems for which part power operation is very important, the operation of multiple engines in combination is described.
