Preliminary studies of the Aero-generator for battery chargingapplication

The present report gives a brief overview of the Indian Small Wind Turbine Market. The macroscopic scenario is presented and aspects such as domestic and foreign marked potentials, barriers, technology needs and the strategies required to boost the small wind turbine sector are presented. NAL’s wind turbine development program, since its establishment in 1959, has been presented and different machines developed at NAL. Finally, NAL’s vision of developing a 500 W class stand alone horizontal axis wind turbine for battery charging is explained. This project would aim at utilizing NAL’s experience and expertise in aerospace domain to develop an indigenous wind turbine system. A variant of this can be considered for urban and military application also. The basic strategy is explained. The report ends with a note committing the realization of a 500 W wind turbine system, whose development would be consumer as well as market driven. The report gives a strategic description of the project and no technical issues have been included. However, subsequently, as NAL progresses along its predefined strategy of developing 500 W wind turbine under the 11th Five Year Plan, the technical and design reports of all the aspects like rotor aerodynamic and structural design, drive-train, generator, tower and controller would be brought up.
