Variable Compression Component Interpolation Method for Turbine Engine

In the variable-cycle engine performance calculation model which is established based on the component method, the acquisition of variable compression component parameters is one of the keys to iterative calculation. In this paper, a new interpolation method is proposed and verified for the characteristics of variable compressors with adjustable first-stage vanes and adjustable two-stage vanes. Using the proposed two interpolation methods, the steady-state throttling performance of a turbine engine with variable compressor was calculated.
