WindPitch is a genuine miniature wind turbine (wind power generator) designed for students to evaluate the pitch (setting angle) of the profiled blades. Up to 12 profile blades can be installed concurrently for evaluation. Learn how blade pitch and number of blades affect the power output of the wind turbine to maximize the output power. Experimentation also gives real-world experience with stalling or reduction of the wind turbine's rotational speed to protect itself under strong wind conditions. WindPitch includes 3 different types of profiled blades and 1 type of Polypropylene sheet blades in a complete package that allows for the evaluation of many types of blade parameters. The special 3-Phase AC alternator used in the WindPitch is similar to the one used in real commercial wind turbines. WindPitch comes with a LED Voltmeter / Music Maker Module to demonstrate how wind energy generated power can be used practically in the form of sound and the illumination of LED lights. This kit includes a complete curriculum on wind energy with an easy-to -follow experiment manual, assembly guide and background history on the technology and wind power generators.
