| 摘要 |
<p>This invention is a free spinning annular cylinder-like hollow body (10), having a leading and trailing end which are open at the ends. The leading end contains a balanced, uniformly and heavily weighted dense rim (14) for generating gyroscopic forces. when the device is propelled forward with a spinning motion about an axis in substantially the direction of flight, the body (10) is gyroscopically stabilized, in reference to direction, attitude and orientation. The weighted rim also shifts the body's center of gravity (42) toward the center of pressure, near the leading edge, which enables creation of lift.</p> |
