Sensitivity and Design Point Analysis of RD-93 Engine at Static Sea Level using Numerical Propulsion System Simulation

Abstract

The design and prototyping of jet engines is an extremely costly and laborious task. An alternative to at this is the development of variants of existing engines for enhanced performance which requires detailed modeling of engine in mathematical environment for precise evaluation of performance parameters. This paper presents mathematical modelling and sensitivity analysis of performance of RD-93, a low bypass turbofan engine, towards design parameters including pressure ratio of turbomachinery components, bypass ratio and critical temperatures. The effect of varying the efficiency of engine components on performance of overall engine is estimated using numerical environment of Numerical Propulsion System Simulation (NPSS). The results of performed analysis can serve as a guide for further parametric cycle analyses of low bypass turbofan engines.
