Aeroacoustic measurements and analysis have been made for an unshrouded rotor partially
immersed in a planar equilibrium turbulent boundary layer at low Mach number. This …

When an aircraft is operating in static or near static conditions during taxiing or take-o a
vortex can form between the ground and the intake. With engine diameters increasing …

This work describes a computational study into lip stall in subsonic civil aircraft intakes and
its alleviation by action of the fan. Beyond a certain flow incidence, the lower lip of a civil …

The main role of the intake is to provide a sufficient mass flow to the engine face and a
sufficient flow homogeneity to the fan. Intake-fan interaction off design represents a critical …

The aim of this research is to analyze the flow generated by the interaction between a
simplified linear blade cascade adapted from an industrial aircraft engine demonstrator and …

The development of ground vortices when an intake operates in close proximity to the
ground has been studied computationally for several configurations including front and rear …

Forced response analysis has become commonplace for predicting the vibration amplitude
of turbomachinery blading. These analyses are usually limited because they rely on …

Ultra high by-pass ratio (UHBR) turbofan configurations are promising concepts to address
the issue of aircraft fuel burn reduction. The large fan diameter and the small ground …

Aeroelastic phenomena in the low-pressure compression (LPC) system of civil turbofan
engines can cause a significant high-cycle fatigue (HCF) risk to the LPC components …

The ground vortex generated in front of an intake operating near the ground and subjected
to crosswind is investigated using CFD and compared to the experiments. The flow field of a …
