The amount of lift you would get from such a small amount of helium would be practically negligible compared to the weight of the aircraft. Lighter-than-air craft require an enormous volume of helium/hydrogen - due to the cross-section of such a craft, the speed of travel is severely limited by drag. Basically, an aircraft uses wings OR lighter-than-air gas - it can't use both. |
