Aircraft Fuel Tank - How Long Can A 747 Fly Without Refueling?

A modern Boeing 747 can fly about 15,000 km (9,500 miles) when it's flying at 900 kmh (550 mph). This means it can fly non stop for almost 16 hours!

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.

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.

How much fuel is used on takeoff?

A jumbo jet uses around 5,000 gallons (almost 19,000 liters) of fuel to take off and climb to cruising altitude. This is about a tenth of its entire fuel capacity. Once airborne, most jumbo jets use about five gallons (19 liters) of fuel per mile.

Where is fuel tank in 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.

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.

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.

Are fuel tanks pressurized?

The fuel tank is supposed to be pressurized so that gasoline vapors can be controlled and captured, rather than released into the atmosphere.

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 much does it cost to fill up a 747?

A 747 can seat 380 to 560 people, depending on how an airline sets it up. A full one is a moneymaker. But an airline that can't fill all the seats has to spread the cost of 63,000 gallons of jet fuel — roughly $200,000 — among fewer passengers.

What is aircraft fuel pump?

Aircraft fuel pumps are an integral component of an aircraft fuel system, which enables fuel to be loaded, stored, managed, and delivered to the engine. Engine-driven fuel pumps deliver a continuous supply of fuel at the proper pressure during engine operation.

What are the 3 types of fuel?

Types of Fuels:

• Solid Fuels.
• Liquid Fuels.
• Gaseous Fuels.

What are the 3 basic types of aircraft fuel tanks?

Fuel tank construction can be divided into three basic types: integral, rigid removable, and bladder. An integral fuel tank, shown in Fig. 15-1, is a tank that is part of the basic structure of the aircraft. Integral fuel tanks have commonly been located in the wing or fuselage, as illustrated in Fig.

Why are fuel tanks in the wing?

The weight of the fuel provides rigidity to the wing, thereby reducing wing flutter (vibration of the wings due to the airflow). Large flutter is so hazardous that it can even result in total collapse of the wing. Thus, storing fuel in the wings is an exceptionally wise decision which keeps aircraft flying!

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.

What grade of aluminum is used for fuel tanks?

All things considered, the recommended fuel tank material is 5052, either 1/4 or 1/2 hard aluminum. The 5052H32 designation is for the 1/4 hard, and the 5052H34 designation is for the 1/2 hard aluminum. The 5052H32 aluminum is very easy to form and is readily available from homebuilt suppliers.

How many types of aircraft fuel tanks are there?

Aircraft typically use three types of fuel tanks: integral, rigid removable, and bladder. Integral tanks are areas inside the aircraft structure that have been sealed to allow fuel storage. An example of this type is the "wet wing" commonly used in larger aircraft.

What is aircraft tank unit?

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

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.

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.
