Fuel tank aircraft

In a modern, multi-engine passenger or cargo aircraft, the fuel system is likely to consist of multiple fuel tanks which may be located in the wing or the fuselage (or both) and, in some cases, in the empange.

What is the fuel tank capacity of an aircraft?

A small plane can have a fuel capacity of 4000–5000 liters, a mid-sized plane can have 26000–30000 liters, a wide-body jet can have 130000–190000 liters, and a very large jumbo jet can have 200000 liters to 323000 liters.

How do aircraft fuel tanks work?

Jet transport aircraft supply fuel to the engines via in-tank fuel boost pumps, usually two per tank. They pump fuel under pressure through a shutoff valve for each engine. A manifold or connecting tubing typically allows any tank to supply any engine through the use of crossfeed valves.

Which fuel tank is used first in aircraft?

On two- and four-engine airplanes, center tank fuel and auxiliary tank fuel are generally used first. Once these tanks are empty, fuel is used from the wing tanks.

What are airplane fuel tanks made of?

They typically are made from 3003 or 5052 aluminum alloy or stainless steel and are riveted and seam welded to prevent leaks. Many early tanks were made of a thin sheet steel coated with a lead/tin alloy called terneplate. The terneplate tanks have folded and soldered seams.

How big is a 747 fuel tank?

A Boeing 747 can hold approximately 48,400 – 57,285 gallons of jet fuel depending on the model of aircraft (model series 100 – 400). This is 183,214 to 216,847 liters of fuel or about 180 to 213 tonnes.

How much fuel does a 747 hold?

Let's start with a look at the most famous of jets, the Boeing 747. The Boeing website states that this model, with a gas tank capacity of 63,500 gallons, may burn five gallons of jet fuel per mile of flight. A 4,000-mile flight, then, requires 20,000 gallons of fuel.

How many Litres of fuel does a 747 hold?

According to the Boeing website, the 747 burns approximately 12 litres per kilometre. 747 can carry as many as 568 people. It can carry up to 238,840 litres of fuel.

Are aircraft fuel tanks pressurized?

Each tank is vented (or pressurised) to allow air into the tank to take the place of burned fuel; otherwise, the tank would be in negative pressure which would result in engine fuel starvation.

What are the two types of fuel systems on an aircraft?

There are two main types of aviation fuel used in general aviation: jet fuel and AVGAS. Jet fuel is a refined kerosene-based, clear or straw-colored liquid that is primarily used to power turbine engines, such as turboprop and jet engines.

Where is the fuel stored in a 747?

Fighter jets often have fuel stored behind the pilot's seat, but big airliners like the B747 store massive amounts of fuel in their wings.

What is aircraft tank unit?

The tank unit is the component which gives the system its name “Resistive Fuel Quantity Measuring System”.

How do you fuel an aircraft?

Generally, at airports, fuel providers have low-rising fuel trucks that can park under or next to the wings. The driver connects the hose to the wing and can pump the kerosene in at a rate of 634 gallons per minute (2,400 liters per minute). This can take anywhere from 15 to 20 minutes to refuel an aircraft.

How is fuel measured in aviation?

In jet aircraft, fuel is measured in pounds due to the fuel volume is changed based on the temperature. This is very critical when a jet flies in high altitudes where the temperature will be -40 to -50 Fahrenheit. Furthermore, fuel is consumed by mass rather than volume.

How thick are aluminum fuel tanks?

The American Boat and Yacht Council (ABYC) recommends that the aluminum fuel tank consists of alloys grade 5086, 5083 or 5052. They specify that the minimum thickness is no less than 0.90 inches for smaller tanks and for larger tanks should be no less than . 125 inches and no thicker than .

How are the fuel tanks vented in a modern passenger aircraft?

There is one fuel tank in each wing (divided into an inner and outer cell) and one in the center wing box. There are also two vent surge tanks. The vent surge tanks are located in each wing outboard of the wing tank. Each vent surge tank vents to the atmosphere through a NACA type intake connected with a vent duct.

Is aluminum good for fuel tanks?

Aluminum gets its strength from its high-density properties. This high-density makeup, coupled with aluminum's low melting point, makes it ideal for marine fuel tanks, as it can endure the fabrication process without losing its ability to resist water damage.

Can a plane land with full fuel?

Yes, you can safely land with full fuel. There are many Boeing 767 and Airbus A300, A310, and A330 that no not have fuel dumping capability. They just land overweight in case of an emergency and then do an overweight landing inspection. 737s also lack fuel-dumping equipment.

How much fuel does a A380 hold?

A fuel capacity of nearly 82,000 gallons, a fuel consumption rate of 10 g/nm and space for up to 853 passengers makes the A380 more fuel efficient per passenger than an average economy car.
