They are added fuel tanks so the aircraft can carry more than the normal amount of fuel ; for example, for longer range, or greater endurance.
Yes, trapped fuel is included in the basic weight of an aircraft because it represents the weight of fuel that cannot be used for flight. This weight is accounted for in the aircraft's operating weight calculations.
Jet fuel is measured in pounds because it is a unit of weight that is used to quantify the amount of fuel loaded onto an aircraft for safe operation. By measuring jet fuel in pounds, it allows for accurate calculation of the weight and balance of the aircraft during flight planning and ensures that the aircraft stays within its weight limitations for takeoff and landing.
Takeoff weight is the total weight of an aircraft at the moment it lifts off the ground, which includes fuel, payload, and the aircraft itself. Landing weight is the weight of the aircraft at the moment it touches down on the runway, which is typically lower than the takeoff weight due to fuel burn during the flight. These weights are calculated based on the initial weight of the aircraft, fuel consumption, and payload changes during the flight.
A nacelle is a streamlined enclosure on an aircraft or a rocket, typically used to house an engine. It is designed to reduce drag and improve the aerodynamic efficiency of the vehicle by providing a smooth surface for the airflow to pass over. Nacelles can also contain components such as cooling systems, exhaust outlets, and fuel tanks.
Hydrogen energy can be stored in various ways, including compressed gas tanks, liquid hydrogen tanks, and solid-state storage materials. These storage methods allow hydrogen to be used as a fuel for various applications, such as in fuel cells for generating electricity or in hydrogen-powered vehicles.
Jumbo jets have several fuel tanks. The majority of these fuel tanks are located in the wings of the aircraft. Some aircraft may also have auxiliary tanks in the tail or belly. The Douglas (now Boeing) MD11 has a fuel tank in the Elevator(horizontal tail surface) that is used to balance the aircraft to fly at altitude with less drag.
conformal fuel tanks
Fuel is generally stored in tanks built into the wings.
To utilize the wing space for the fuel,
Where is the fuel tanks located on small planes? Most of the fuel tanks are located in the wings of the aircraft. There is usually the main tanks that are located in the center of the wings and then there are tip tanks, that are located towards the wing tips.
In most modern aircraft they are in the wings.
Wings and belly.
On vehicles with dual tanks, the front tank is the main and the rear tank is the auxiliary. The main fuel balance pump supplies fuel to the fuel injection unit. The low pressure, about 32 kPa (7 psi) fuel balance pump is used only to transfer fuel from the auxiliary tank to the main tank in order to balance the fuel levels in both tanks. As the main tank level drops to about 25 percent below the level in the auxiliary tank, the fuel sender and balance module energizes the fuel pump relay. This pumps the fuel from the auxiliary tank to the main tank. When the level in the main tank reaches a level slightly higher than the level in the auxiliary tank, or the auxiliary tank is empty, the module de-energizes the balance pump relay and fuel pump. Any malfunction in either of the fuel gauge circuits will disable the system and the fuel will not be transferred from the auxiliary fuel tank to the main fuel tank.
Aircraft use three types of fuel tanks using: (1)integral (2)rigid removable (3)bladder.
In the event engine-driven fuel pump fails.
Those are external fuel tanks, which can be dropped from the plane in flight when they run out of fuel, increasing the aircraft's range. They are also usually dropped when entering a dogfight, in order to reduce weight and make the aircraft more aerodynamic.
It's called 'unusable fuel.' The stats in the operation manual will always state the total fuel capacity and unusable fuel. When there are multiple tanks in multiple locations, the unusable fuel in all tanks will be stated.
