OSTI ID:7132141
The conventional multibladed windmill - a functional, reliable, long-lasting, economical-range water-pumping system - has been in use for over 125 years. However, work continues on improvements to the conventional windmill and the development of new designs such as: Fully counterbalanced windmill; Spring-counterbalanced windmill; Cam-operated windmill; Hydraulic system which replaces the pump rods of a conventional windmill; Automatic stroke control for a conventional windmill; Automatic stroke control for a three-bladed wind turbine; Electric wind ac generator driving an ac submersible pump; Electric wind dc generator driving a dc submersible pump; Windmill-driven air compressor operating an air-lift pump; Long-life well cylinder; Performance modeling and testing of windmills.
