Rockets at lift-off, however, have practically zero external aerodynamic damping and the jet damping becomes significant.
2.
For jet airplanes in cruise, the contribution of jet damping is usually negligible because the external aerodynamic damping is large relative to the jet damping.
3.
In such vessels, the rolling motion is not uncomfortable because of the moment of inertia of the tall mast and the aerodynamic damping of the sails.
4.
The researchers found that the presence of these glue droplets increased the wind resistance of the web and enhanced aerodynamic damping by about 35 percent, she said.
5.
The researchers said they confirmed their computer findings by firing Styrofoam bullets at real webs, including some with sections of the web net cut away to reduce aerodynamic damping that disperses energy.
