Investigation into the calculation of aerodynamic damping of structural assemblies
Computers & Structures, 1993Abstract Methods of calculating the dynamic damping are presented. Various aspects of damping and their effects on tension structures are studied. These aspects are damping systems and their effects on the equation of motion; the influence of air on vibrating structures; calculation of the damping coefficient and the air damping due to a phase lag ...

Investigation on the aerodynamic damping of a stator in tandem arrangement
Proceedings of Global Power & Propulsion SocietyThe challenge to significantly reduce emissions requires future aero engines to have an increased efficiency as well as reduced weight and size. In this context, stators with tandem arrangement are used to allow the compressor to have a minimum number of stages along with reduced blade and vane counts while maintaining or increasing the overall ...

Mass-flow sensor using aerodynamic damping
The Journal of the Acoustical Society of America, 1991A fluid mass flow sensor uses the effect of aerodynamic drag on a vibrating object. The drag damps the resonance oscillations of the vibrator in an amount proportional to the mass flow. An electronic feedback circuit associated with the mass flow sensor has the effect of allowing for fast response time despite the use of a high Q vibrator and allows ...
