The paper presents the development of conceptual alternate designs and working design of a portable windmill that can be used to supply electrical power in remote locations, such as camping areas where large gas or diesel-powered generators are not feasible because of shipping costs, or an increasing number of fire bans instituted during dry seasons. Campers and hunters affected by fire bans need a portable power supply to provide lighting, heating, and cooking. Data was collected on wind

... power requirement, and shipping space available in most car trunks. The collected wind data, power requirements, and shipping limitations were reviewed, and design specifications were developed for the design of a portable windmill. Two alternate conceptual designs were developed for the windmill. The two designs were reviewed for manufacturing and cost considerations. One of the two concepts was selected for development into a working design of the windmill and its components. Synthesis, analysis, and working drawings, that include assembly and detail drawings of components, were developed for the selected design concept. Designs for windmill components such as: blade, hub, gearbox, shafts, tail fin, and frame, etc. were developed. Standard components were used in the design of the windmill wherever it was possible. Capabilities of the proven CAD program, Pro/ENGINEER, and FEA program, ANSYS, were used in designing the windmill components. Finite element analysis results and working drawings of the intricate mechanical components of the windmill are provided in this paper.
