Prediction of damping coefficients using the unsteady Euler equations

, 2003
A prediction method for dynamic damping coefficients using the unsteady Euler equations is presented. Direct unsteady simulation can be used to compote the pitch-damping moment without any geometric approximations when compared to the steady methods ...

Measurement and analysis of moment of inertia using torsional pendulum method with air damping consideration

Jixie qiangdu
To address the issue of accuracy degradation caused by aerodynamic damping when measuring the moment of inertia of irregular specimens with large airfoil surfaces using the torsional pendulum method, a compensation approach based on drag simulation ...

A theoretical solution of a water- spherical shell-damping layer interaction system for underwater noise reductions

Based on a fluid-structure interaction analysis (FSIA), the theoretical solution is developed for an integrated spherical shell-damping layer-water interaction system subjected to an internal sinusoidal pressure excitation. The effect of damping layer on
