Fuel tanks on the plane. Where are? Design.

 

Fuel tank - a tank that stores liquid fuel, it is placed directly on board the aircraft. From fuel tanks are the fuel wires to the power plant that provides its power fuel. Also on board the aircraft can be placed tanks for fuel supply heating systems.

Turboprop and turbojet aircraft engines use in their work with additional jet fuel additives. Light aircraft, equipped with a piston power plants, as fuel use gasoline with high octane number.

In modern aircraft used caisson tanks, they have the form of sealed cavities. They are mainly installed in the wings, stabilizer and keel. These are soft tanks made of rubber materials, it allows to preserve their integrity during overloads and impacts. In addition, this material is very reliable and effectively occupies the allocated space.

Sometimes they use tanks, compartments, which operate as a part of the fuel tank, and the role of the power element. To prevent spilling fuel from the caisson-tanks, fighter planes using the sponge-type foam filler.

Large airliners, which are designed for long-distance flights are more fuel tanks, which are additionally equipped with pumps. All fuel tanks are interconnected fuel system of wires that allow the use of fuel from any tank or produce it pumping. Pumping fuel from one tank to the other is possible thanks to the implementation of a more efficient alignment of the aircraft. Fuel is pumped from supply tanks to spare, respectively, developed a program of fuel consumption in flight.

It should be noted that the process of filling fuel in the tanks of the aircraft takes place in accordance with the plan of alignment. Fuel is supplied to the tanks of the apparatus under pressure through a special tanker neck, after which it is distributed between the tanks.

Each fuel tank within the aircraft has the so-called discharge spout through which all the fuel can be drained. After each refueling carried out the opening of the mouth, allowing the drain deposited on the bottom of the tank or water condensation. Naturally, in the tank there should be no impurities, otherwise it may cause engine failure and accidents.

Also, aircraft have the emergency discharge of fuel in the air. This system is required for the emergency landing immediately after takeoff, as the allowable weight of landing aircraft is significantly less than the take-off weight.

Combat aircraft, which is necessary to carry out combat operations at great distances from the base, can be equipped with extra fuel tanks suspended type. They are streamlined to improve the overall aerodynamics and suspended from the fuselage or wing aircraft. After generating all the fuel they are discharged. Also, such devices are applied for the distillation of other aircraft on airfields dislocation, they are usually installed in the middle of the body.

Safety fuel tanks

Combat aircraft and some passenger cars use neutral gas to fill tanks, which is supplied as fuel is consumed. Carbon dioxide or nitrogen is used as a gas. This helps prevent a fire on board or an explosion in the fuel tank due to mechanical damage. A similar scheme of filling with gases in the fuel tank was used in the Second World War, only cooled exhaust gas from the engine manifold was used as gas. 

The text is obviously translated and therefore there are mistakes in the description of aviation technology. For example: "caisson tanks, they look like sealed planes". A tank in the form of a plane is original.
