Uji eksperimental kincir angin poros horisontal dengan sudut sudu (15,20,25) derajat dan jumlah sudu 16 untuk mendapatkan daya dan efisiensi optimum (CD)
These day requirement of electrics energy is through increase, while the electrics energy from PLN is very limited. To overcome these problem need some appliance that can produced alternative electrics energy. Windmill with horizontal axis is represent one of producer of electrics energy alternative.
Good or not windmill one of them is influence by angle of blade. To get the best value of angle of blade at windmill require to be done by furthermore experiment. From this experiment will get the best value of angle of blade that can to produce the high energy and the high torsi.
The object test is horizontal axis windmill with 16 of blade. These blade have square form with dimension of length 60mm and wide 15mm, and also have curvature 500. for the angle of blade used three kind of variation is 150, 200, and 250. experiment was done at wind tunnel at Prestasi Mesin laboratory of Merdeka University Malang. From result of experiment will be got energy of wind mill.
From result of experiment and data processing can know that angle of blade 200 is representing the best of angle of blade among third angle of blade was taken as variation. At angle of blade 200 got the highest energy and also highest efficiency.
