During the nineteenth and twentieth centuries, Dutch millwrights developed the windmill sail to make it more efficient aerodynamically and operation easier in an effort to keep the traditional windmill economically viable in competition with factories and electric pumping stations. Dekker / Van Bussel system The Dutch millwright A. J. Dekker improved on the efficiency of the common sail. The stock is given an airfoil shape by completely covering it with galvanised steel plates. Dekkerised sails provide enough surface area to be able to work the mill with no sailcloth spread if the wind is strong enough. As with the common sail, they are not adjustable except by adding more sailcloth. Some disadvantages of the Dekker system led millwright Van Bussel of Weert to invent a similar system, though with just a more rounded airfoil replacing the leading boards and not covering the stock itself. Ten Have / Beckers Invented by Dutch millwright Ten Have of Vorden, Ten Have sails have a small number of wide longitudinal shutters, operating by centrifugal weights and often also by the miller at the tail of the mill similar to patent sails. This way the sail can be adjusted without stopping the mill. The leading edge is commonly streamlined by the Van Bussel system. Ten Have shutters are normally only used on one stock as the wide Ten Have shutters standing open on a vertical stock would leave this stock vulnerable to side winds during a storm. Beckers sails are an alternative to Ten Have sails. Only two mills in the Netherlands were fitted with them. FauC+l or Fok system The Fok system, invented by engineer P.L. FauC+l, was inspired by the jib on a sailing boat ('fok' is the Dutch word for jib). In this design the leading boards are replaced by a rounded profile of wooden slats in the form of a foresail leaving a small slot between this profile and the stock. Its working principle can be compared to a leading edge slot on an aircraft wing. It enables the mill to work in a lower windspeed but in variable windspeeds tends to make it difficult to have the mill run at a steady pace. For this reason it is often equipped with air brakes operating by centrifugal force. The FauC+l system is used in addition to common sails (see photo). Bilau Ventisails/ Van Riet system The Bilau system uses sails with a streamline covering of the stock, coupled with a full length air brake on the trailing edge, together forming an airfoil. The airbrake is opened by centrifugal weights in the sails but can also be operated by the miller similar to the patent system. When opening the airbrake disturbs the airfoil shape thereby slowing the mill. It was invented by German airplane engineer Kurt Bilau early in the twentieth century and became quite popular in Germany where it was fitted to over 140 mills. A similar system was invented by a millwright by the name of Van Riet of Goes where the leading edge and ------------------------------ Date: Tue, 18 Aug 2020 11:54:44 -0400 From: "Massive Male Plus Basic" Subject: Do This For 1 Minute To Unlock Massive Growth Do This For 1 Minute To Unlock Massive Growth http://sardable.cyou/j_aXxWTQWjlFzCkhKhl6gi-steoeoZEpGK3s68d1gruiI_Hu http://sardable.cyou/63ixkelaiyvlwFI6tbJZhtn0sl5P4Bz47pXuKh7P2KwpM-MX The Netherlands is well known for its windmills. Most of these iconic structures situated along the edge of polders are actually windpumps, designed to drain the land. These are particularly important as much of the country lies below sea level. In the UK, the term windpump is rarely used, and they are better known as drainage windmills. Many of these were built in The Broads and The Fens of East Anglia for the draining of land, but most of them have since been replaced by diesel or electric powered pumps. Many of the original windmills still stand in a derelict state although some have been restored. Windpumps are used extensively in Southern Africa, Australia, and on farms and ranches in the central plains and Southwest of the United States. In South Africa and Namibia thousands of windpumps are still operating. These are mostly used to provide water for human use as well as drinking water for large sheep stocks. Kenya has also benefited from the African development of windpump technologies. At the end of the 1970s, the UK NGO Intermediate Technology Development Group provided engineering support to the Kenyan company Bobs Harries Engineering Ltd for the development of the Kijito windpumps. Bobs Harries Engineering Ltd is still manufacturing the Kijito windpumps, and more than 300 of them are operating in the whole of East Africa. In many parts of the world, a rope pump is being used in conjunction with wind turbines. This easy-to- construct pump works by pulling a knotted rope through a pipe (usually a simple PVC pipe) causing the water to be pulled up into the pipe. This type of pump has become common in Nicaragua and other places. Construction To construct a windpump, the bladed rotor needs to be matched to the pump. With non-electric windpumps, high solidity rotors are best used in conjunction with positive displacement (piston) pumps, because single-acting piston pumps need about three times as much torque to start them as to keep them going. Low solidity rotors, on the other hand, are best used with centrifugal pumps, waterladder pumps and chain and washer pumps, where the torque needed by the pump for starting is less than that needed for running at design speed. Low solidity rotors are best used if they are intended to drive an electricity generator; which in turn can drive the pump ------------------------------ End of alt.music.moxy-fruvous digest V14 #4807 **********************************************
