What happens to fighter jet drop tanks?

They are called drop tanks. When a drop tank is jettisoned, very likely it is not retrieved and reused. This is also the case with (sadly, discontinued) Space Shuttle external tank. Those tanks were not reused either.

How do drop tanks work?

Some of the drop tank’s fuel is used to overcome the added drag and weight of the tank itself. The use of drop tanks also reduces the number of external hardpoints available for weapons, reduces the weapon-carrying capacity, and increases the aircraft’s radar signature.

Why are aircraft fuel tanks vented to the outside?

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. A vent also allows for changes in atmospheric pressure and temperature.

Where does the fuel in an airplane go?

On passenger planes, fuel tanks are often integrated into the wings, and when there are also tanks inside the body of the aircraft, the wing tanks are used preferentially. The placement reduces the stress on the wings during takeoff and flight, by putting the heavy fuel directly inside the source of lift.

Are drop tanks actually dropped?

Drop tanks aren’t exactly expendable but they can be dropped when in combat. Drop tanks are meant for extra fuel for longer range missions and they are designed for the least amount of drag. You are supposed to keep them on so you save money. If you drop them for no reason you’ll be penalized for it.

What are aircraft drop tanks?

Definition of drop tank : an auxiliary fuel tank for airplanes that can be jettisoned (as when empty)

How does external fuel tank work?

The External Tank includes a propellant feed system to duct the propellants to the Orbiter engines, a pressurization and vent system to regulate the tank pressure, an environmental conditioning system to regulate the temperature and render the atmosphere in the intertank area inert, and an electrical system to …

What happens if a fuel tank is not vented aviation?

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.

Why is it necessary to drain fuel out of the sumps after refueling and before the first flight of the day?

co Aircraft Fuel Tanks. Aircraft fuel tanks are constructed with sumps to trap water. Since it is practically impossible to drain all water from the tanks through the fuel lines, the fuel tank sumps should be regularly drained in order to remove all water from the system.

How many fuel tanks were there in the plane how much fuel was left?

How much fuel was left? Answer: There were two fuel tanks in the plane. The pilot had already switched over to second and the last tank so there was enough fuel only to fly back to England.

What type of fuel is used in aircraft?

Aviation kerosene, also known as QAV-1, is the fuel used by airplanes and helicopters equipped with turbine engines, such as pure jet, turboprops, or turbofans. Our kerosene’s thermal stability ensures the aircraft’s performance.

Can external fuel tanks be used as bombs?

Known as “drop tanks,” these simple devices extend the range of the aircraft they’re hooked up to by carrying extra usable fuel. Back during World War II, however, attack pilots found a secondary use for drop tanks as improvised bombs, used to bombard enemy ground positions.

Why do some aircraft have fuel in their drop tanks?

Some of the drop tank’s fuel is used to overcome the added drag and weight of the tank itself. Drag in this sense varies with the square of the aircraft’s speed. The use of drop tanks also reduces the number of external hardpoints available for weapons, reduces the weapon-carrying capacity, and increases the aircraft’s radar signature .

What happens to fuel tanks when they are empty?

In real combat, external fuel tanks are jettisoned when empty or as soon as the aircraft needs to get rid of them to accelerate and maneuver against an enemy fighter plane or to evade a surface to air missile. Several thousand drop tanks were jettisoned over Southeast Asia during the Vietnam War.

How many gallons is a drop tank on a plane?

A 600 US gallons (2,300 L) Sargent Fletcher drop tank being moved across the flight deck of an aircraft carrier In aviation, a drop tank (external tank, wing tank, or belly tank) is used to describe auxiliary fuel tanks externally carried by aircraft. A drop tank is expendable and often jettisonable.

Which fuel tank is used first in an airplane?

Usually the fuel in the drop tanks is consumed first, and only when all the fuel in the drop tanks has been used, the fuel selector is switched to the airplane’s internal tanks. Some modern combat aircraft use conformal fuel tanks (CFTs) instead of or in addition to conventional external fuel tanks.
