The air flow in the Bernoulli drive is governed by the Bernoulli principle. The Bernoulli effect is so called because it was first documented and described by the 18th Century Swiss mathematician, Daniel Bernoulli. It deals with a particular phenomenon of the fluid dynamics of moving air or water. Bernoulli noticed that when air moves rapidly over an object, it exerts less pressure on the object. When the air flows more rapidly over the curved surface of an airplane wing, for example, the diminished pressure on the top of the wing causes the wing to lift. The effect is exploited in the Bernoulli drive by passing air rapidly over the flexible recording disk. The disk, which normally droops away from the |read/write head|, is lifted by the reduced pressure above it.
