Five Power Generating Windmills. Final Report

摘要

Five electric power generating windmills are being installed on two 80 ft. self supporting steel towers and three atop 90 ft. guyed steel towers. The generators are rated 1800 watts at a wind velocity of 24 mph and have a maximum capability of 2100 watts at 28 mph. The prime power is a 3-bladed prop having a peripheral diameter of 13 ft. The windmill will start turning when the wind velocity reaches 9 mph at which speed it will generate about 200 watts. Power increases approximately 130 watts with each 2 mph increase in wind velocity. (ERA citation 09:011828)
