Airplanes - Why dont they have helium underneigh the plane.? - helium gas bottles
Logically, this would increase the aircraft, establishing and helping to maintain altitude during the flight. How it works is a kind of test chamber by a rubber ball to inflate the wheel when the aircraft is on the point of making it easier for one hand in front of him and maintain a certain percentage during the flight, the wings and the engine is not working so hard, and he treats the earth, deflate than helium back into the gas chamber in the cylinder and therefore inertial safely land the aircraft. PS: a small part of the helium can also be used to soften the landing of a traditional schedule. PS 2 heavy items should be placed in front of the plane, like a steel plate so that the focus move to continue with the engine torch and the light weight of the helium act l level.
The gas must be stored in the luggage room of steel, and helium is inflated in a layer of plaque within 10 meters of air passengers.

Helium Gas Bottles Airplanes - Why Dont They Have Helium Underneigh The Plane.?

The helium would have the same effect as if it were in his "bottle" or "rubber-tray" does not save much at all. The mass is a constant, regardless of where helium is the airplane. It takes about 700 g of helium to 1 kg, giving a neutral buoyancy. 747-400 weighs 179.000 kilograms of fuel or cargo, so that neutral buoyancy 125.300 kilograms of helium, which gives a total weight 304.300 kg. A full passenger load (payload) and max. Fuel has a maximum weight of the main taxi 397.000 kilograms of fuel weigh only 216.840 kilograms. With enough helium to ensure neutral buoyancy of the aircraft, which weighs approximately 674.900 kilograms, which is outside the operating parameters.
This does not work for many reasons.
First vehicles, aircraft difficult. Moreover, the weight of all passengers and luggage. Require an absolutely huge helium bag to reduce this burden slightly.
Second, you have the greatest weight of the bag itself (which have also not hard), and all the helium tanks and all equipment necessary to inflate / deflate / storage bag.
Then there is the effect of air resistance. Even if you could with a pocket big enough and has the speed, temperature changes and possible collisions with birds survive, had fuel to spend more money to outweigh an object so big push in the air far no weight economies in the background to gain a little easier.
