Abstract
The reduction of greenhouse tax emissions concerns the world. Power plants moved by fossil fuels and their use in industrial processes have generated an incessant search for alternatives, both in energy production and industrial process adjustment, to mitigate the impact on the environment. In this work, the main objective is to show the stages of the design of a small horizontal axis wind turbine to attend an installation of a small hotel in Ajuruteua-PA-Brazil to encourage tourism, generating employment and income for the local population. Also, making it viable by reducing the project operating costs. The rotor blade geometric characteristics were designed by the methodology based on the Blade Element Momentum analysis. The optimization proposed by Glauert is employed, using the corrections proposed by Prandt and Viteran & Corrigan for the finite number of blades and post-stall behavior, respectively. Wind measurements from the locality were used to estimate the rated wind speed at which the rotor blade was optimized. As a result, an estimative for the starting, aerodynamic torque of the rotor was determined, neglecting the pitch angle adjustment of the blades, as in most small wind turbines, making starting at low wind speed still a severe challenge in the literature.
