After all teams have had a turn at the test station and have completed their worksheets, conclude with a class discussion. A wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power, and other systems to start, stop, and control the turbine. Generator and gear box can be placed near the ground using direct drive from the rotor assembly to the ground based gear box, hense improvimg assesibility for maintenance. (Grade 4). WinDIY is a design of a (mostly) 3D printed wind turbine. This lesson provides students with an overview of the electric power industry in the United States. within type by subtype, then by grade, etc. Customer Needs and Accompanying Metrics and Specifications For this project, our design team was given three customer needs: power, durability, and aesthetics. PVC 90-degree fittings A vertical axis wind turbine (VAWT) has its shaft normal to the ground. ), A homeowner wants to use a wind turbine to supply electricity for their home, but no hills are near the house. On the opposite end of the 6-inch pipe, fit a PVC tee, followed by another 6-inch pipe and 90-degree fitting. Think about it: when the wind blows harder, those papers move around even faster. Today, we are going to act as if we are engineers and create small-scale wind turbines that convert wind energy connected to a motor into electrical energy (voltage). (Answer: As high up as possible, such as on a pole above the roof, or on a separate structure that puts it up very high in the air.). Engineers design wind turbines that turn the kinetic energy of the wind (the movement of the wind) into mechanical or electrical power. Snake the motor's wires down the 24-inch PVC pipe; this long section is the tower.2. Wind power does not produce greenhouse gases or pollution. The rotating action of the hub turns a magnet inside a coil of wire in the generator, producing electricity. A turbine is basically a motor connected backwards. For example, a spinning top, a falling object and a rolling ball all have kinetic energy. Using four 90-degree PVC fittings, two PVC tees, and four 6-inch PVC pipe sections, construct the two sides of the turbine base.2. Represent and interpret data.
