We not only specialize in manufacturing different kinds of generators, but also in motors, engines, diesels, gearmotors and other power supply products. We also have more than 100 series of equipment to support and check our products, such as VPI equipment, auto painting lines, auto testing systems and CAD systems. We warmly welcome every customer to cooperate with us on the basis of mutual benefit, and hope to be your faithful friend and best partner. Our custom vortex generators has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS.

The method by which these vortex devices work can be better understood by studying the above diagram of vortex generators on a wing. A vortex generator is much like a miniature wing perpendicular to the main wing. These generators are mounted at an angle of attack to the airflow over the wing so that each creates a vortex off the exposed tip, much like a trailing vortex created by a wing. The above example shows vortex generators aligned in opposite directions so that the vortices they create rotate opposite to each other. These vortices serve to increase the speed of the downstream airflow so that it is "entrained" to follow the sharp curvature of the deployed flap and remain attached to its surface. Otherwise, the airflow would likely separate from the flap causing a loss of lift.

Vortex Generators installed on Stewart Headwind A new design of Vortex Generators for experimental aircraft is now available from Hall Brothers. They were designed and tested in a wind tunnel as well as on various experimental aircraft. In the wind tunnel, many different shapes and angles were tried before reaching this optimum design. Made from .25 6061-T6 aluminum, they are formed in pairs so that the shape and angles are built right in. This makes them easier to install as they only need to be spaced out along a straight line. Also, they can be temporarily attached to the wing with tape for testing without harming the wing surface and then moved or attached permanently. This temporary attachment capability allows pilots to prove out their effectiveness before permanent attachment. The design also gives a generous surface area for bonding.
