position of it automatically during a change in stream direction this also helps keep the turbine system axis perpendicular to moving stream direction 40 the nacelle 21 and interior of platform 29 are sectioned at 5 and provided in fig5 moving stream direction 40 which can be a representation of wind or ocean current observes physical laws similar to a slow moving incompressible fluid the focused circulation 70 71 72 rotates with an axis almost perpendicular to moving stream 40 a higher mass flow rate is produced in the area above 70 71 72 which decreases the backpressure below and downstream of turbine 19 resulting in improved performance the reduced pressure behind the turbine system allows the portion of the stream influencing the turbine system 100 101 102 103 and 104 to have a higher volumetric flow rate to increase power to the turbine than would be available without the augmenters the same conditions are created on the other side of the device hidden from this view to drive turbine 20 the circulating stream 70 71 72 converge at location 76 77 78 toward focus 52 and further reduce the backpressure downstream of the augmenter system for improved device performance as moving stream 40 varies in velocity governor augmentor 12 is able to swing on its hinge 26 since the drag force is proportional to stream velocity during dangerous stream velocities governor augmenter 12 will swing up to a minimum attack angle and greatly reduce the overturning moment on the support structure as a means of protection at sites where stream velocity is unsteady the varying attack angle of the governor augmenter 12 maintains a constant backpressure for improved turbine performance the vertical orientation of the base and governor augmenters require no support for snow loading and reduce requirements.
