  • SHORT DESCRIPTION

    This is horizontal axis downwind type of wind turbine. Due to natural flexibleness in moment of rotor it is necessary to run at downwind, suppose if rotor run at upwind than rotor will vibrate thereby this system work as downwind, due to downwind rotor set properly at their mean position rather than fluctuate. (Fig 12.1, 12.2), In other view downwind is a natural running condition for wind turbine, which does not generate over loading on slewing bearing gear & motor.

    Here rotor is inclined by 2o at upside from CG (Figs 9.1, 08), thereby downward force generates gravity which is equal and opposite to axial force on rotor at 6-8 m/s wind speed, by means CG will shift at right side (reference to Fig 08) by distance 23.5 mm at 00 m/s wind speed, and at 6-8 m/s wind speed it will regain mean position.

    Due to 624 Nm torque at 6 m/s wind speed, thereby generator will exert force on right side (Reference to Fig 9.4, 6.2) shock absorber 7.1 and thereby rotor will exert opposite and equal force on left side (reference to Fig 9.3, 4.3) shock absorber 11.1. To balance improper turning of Generator 6.2 & Axial bearing 2.1, component 10.1 inclined by 3o (Fig 9.3) and Generator base inclined by 2o (Fig 9.4). Thereby rotor will come at mean position at 6-8 m/s wind speed, in this way system is safe from improper turning force by internal required torque for generator 6.2, by those turning reasons rotor inclined by 2o (Fig 9.2) with reference to top view at 00 m/s and this will come at mean position at
    6-8 m/s wind speed.

    Shock absorber 03 is connected to Axial bearing 2.1 thereby load of axial force of rotor managed by Axial bearing 2.1 only, by means that bearings of generator 6.2 are free from axial force or shocks by wind gust. (Fig 01)

    In present wind turbine main axle of rotor is flexible to vibrate at all phase, tilt or move with respect to rotor 12, up to their resonance vibrations. By means vibration, overload, shock impact, cyclic effect etc does not transmits in whole system thereby present wind turbine is free from vibrations, fatigue effects, cyclic effect, rotor racing, vibration coinciding, gyroscopic effect, wind gust, tilting effect etc.
