    The imminent depletion of fossil fuels, increasing global warming, rising greenhouse effect, increasing demand of energy resources, low availability of power supplies moves us towards renewable source of energy like wind energy. In India, agriculture plays a vital role in development of food production. Groundwater pumping using electricity is the most common method of irrigation. But frequent power cuts is one of the most common problem source for farmers in our country and they also do not invest in fossil fuel run pump sets, due to high cost. Hence the main goal of our project is to design and fabricate a wind turbine for generating electricity, pumping water from the reservoir and supplying it to farms via drip irrigation. We used 3-bladed vertical axis wind turbine and reciprocating single acting pump in this project. With the aid of bevel gears, the wind turbine shaft is used to run the reciprocating pump. The wind imposes the lifting and dragging type of driving forces on turbine blades. As these forces act on the blade, it rotates and this rotating blade transforms rotary wind turbine movement into reciprocal pump movement. These is also an automation mechanism where a solenoid valve is used to regulate the water supply. Opening and closing of the valve is controlled by an arduino and soil moisture sensor. The water is effectively discharged this way

    Productivity Improvement of Shakti Power Turbine Labyrinth Cage

    Productivity optimization through re-engineering thefixtures used for labyrinth cage of Shakti engine”, used inadvanced light helicopter. The objective is to improve the productivity of SHAKTI PT LABYRINTH CAGE. Milestone chart was drawn for monitoring the activities. Structured brain storming sessions were conducted, for data collection and analysis of the problem. The problem was categorized under 4M’s (Man, Machine, Material and Method). Each and every cause was discussed in depth for arriving to a root cause. High setup and cycle time of CNC turning operation was due to use of soft jaws and carrying out the operation. This traditional system requires machining of soft jaws every time they are loaded, thus increasing the setup time. Manufacturing department members with our batch discussed all the solutions and solved this problem by developing changes in the fixture and cutting parameters to carry out the above laid operations. There by eliminating the setup time for operation and rejection rate is completely eliminated, also the cycle time was reduced by around 4 hours.
