2015-05-18 (M) Wind Generator Test Base

24" (610mm) threaded rods were too long for the 26" (660mm) spacing due to the clearance of the generating equipment. Additional clearance was also desirable to avoid wind turbulence from nearby turbines. Turbulence was also one reason stations were not all arranged horizontally. To help with clearances the base was angled a approximately five degrees. This small change in angle allows all the stations to sit levelly while each axle will clear the next station. Another option would have been to cut down each threaded rod. Yet another option would have been to remove two of the stations. The test base was angled by twisting the small stabilizing post.

The structure was mounted on a balcony railing using U-bolts on the horizontal rail and bungee cord on the stabilizing post. Natural flexibility in the PVC and bungee cords allowed the structure to withstand strong gusts with no breaking or shifting. Proximity to a nearby tree may cause turbulence but all stations should experience similar turbulence. Testing under less-than-ideal conditions may also reveal a design most suited for implementation.
