| Summary: | In modern jet propulsion systems the core engine has an essential influence on the total engine performance. Especially the high pressure compressor plays an important role in this scheme. Substantial factors here are losses due to tip clearance effects and
aerodynamic airfoil quality. During flight operation the airfoils are subject to wear and
tear on the leading edge. These effects cause a shortening of the chord length and the
leading edge profiles become deformed. This results in a deterioration of the engine
efficiency performance level and a reduced stall margin. |
