Effect of Intake Acoustic Reflection on Blade Vibration Characteristics
Recent studies in turbomachinery have shown that the phase of acoustic wave reflection within an intake can have either positive or negative effects on the aeroelastic stability of fan rotor blades. However, the typical flow structures, such as the shock

Viscous effects on transonic airfoil stability and response [PDF]
Viscous effects on transonic airfoil stability and response are investigated using an integral boundary layer model coupled to the inviscid XTRAN2L transonic small disturbance code. Unsteady transonic airloads required for stability analyses are computed

The effects of aeroelastic deformation on the unaugmented stopped-rotor dynamics of an X-Wing aircraft [PDF]
A new design concept in the development of VTOL aircraft with high forward flight speed capability is that of the X-Wing, a stiff, bearingless helicopter rotor system which can be stopped in flight and the blades used as two forward-swept and two aft ...

On Dynamic Stability of a Nonlinear Aeroelastic System
A nonlinear mathematical model of a device related to vibratory technology is considered. The device is intended for the intensification of technological processes, for example, the mixing process. The action of such devices is based on the vibrations of
