Aerodynamic and Aeroelastic Effects of Design-Based Geometry Variations on a Low-Pressure Compressor
International Journal of Turbomachinery, Propulsion and Power, 2020 In modern aircraft engines, the low-pressure compressor (LPC) is subjected to a flow characterized by strong wakes and secondary flows from the upstream fan. This concerns ultra-high bypass ratio (UHBR) turbofan engines, in particular.
