Balloon kite flight
1/13/12Yesterday Dudu inflated both of the new balloon kites in the shop and left them overnight to insure that there were no leaks. Today we inflated one with helium and launched it outside.
Balloon KITE DATA:
Diameter of Burger: 2000m
Height to Diameter ratio: 0.6
Height of Burger: 1200mm
Volume of an ellipsoid: 4/3 * PI * a*b*c
(a,b,c are each radii, so a=b and c=height)
Volume of our Burger: 4/3 * PI * 1*1*0.6 = 2.5 cubic meters
1 cubic meter = 35 cubic feet
Volume of Burger: 88 cubic feet
We used the 110cubic feet tank of helium to fill and there was some left.
Our 3D gas kite improved the […more]
