Patent ID: 7926339

Claim:
A wind tunnel for using pressurized air flow to suspend objects, the wind tunnel comprising pipes joined together to form loops in a radial layout having radial axes separated from each other by approximately 120°, the loops are formed so as to be combined with one another to create a common vertical air lift section, each loop includes a curved conduit having an upper end communicating with an upper joint connector in a shape of a three point star and a lower curved return end joined to a lower cylindrical air drive conduit, the lower air drive conduits being mounted to converge into a lower three point star shaped joint connector having an upper open end which is mounted to deliver air flow to the vertical section that is connected at an upper end thereof to the upper joint connector, and air flow generators for delivering air through the loops so as to flow upwardly through the vertical section to thereby suspend an object within the vertical section.
