Abstract
This paper describes the feature reducing drag of rotating cylinders in atmospheric air, by the way of wearing floating shrouds covered on the rotor in coaxial. We established the new theory enable to rotate cylinders higher velocity in atmospheric air up to supersonic velocity. We eliminated vacuum containers, vacuum pumps, super conducting magnetic bearings, and other demerits concern to THE VACUUM from flywheels. This new theory have disclosed by us at first in the world in 2002. We will give a full detail of the new theory and instruments for examinations, experimental data and several difficulties on the experiment and phenomena on aerodynamics have come across to the New Floating Shroud Technology.
