Operation LV-426

To calculate power output of the turbine we had to find the wind sweep area, which is found by multiplying the diameter of the blades and the height of the tower. For our VAWT system we used a height of 3.2 feet and a diameter of 30.94 ft to give us a sweep area of 99ft To find our Pwind, we multiplied venus’s air density, of 67, by the wind speed which we assumed to be 2mph on average, and the sweep area by 0.5. To calculate losses we took percentage losses of mechanical loss, transmission loss, efficiency caps, by Bertz Law, and wake loss to find our efficiency. We worked with multiple efficiency ratings to give the best reasonable predictions for our system. To calculate our RPM we multiplied 60 by our wind speed and TSR divided by pi times diameter. Ppower is then our efficiency times our Pwind. TSR was obtained by our Power/RPM times 30/pi. Our initial torque was obtained with the formula T=(Ppower/RPM)*(30/pi). To achieve as much power as possible, we used a two gear gea...
