Numerical investigation of erosion effect on altitude-speed characteristics of a turbojet engine

Abstract

This work devoted to numerical investigation of the effect of compressor blades erosion on the altitude-speed characteristics of a turbojet engine. In the work present-ed estimation methodology of erosion effect on the char-acteristics of compressor and engine as a whole. On basis of obtained results was conducted an analysis of the change of gas-dynamic characteristics of the compressor spools and altitude-speed characteristics of the engine due to the erosion effect.
