fuel in the wings

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!
The fuel storage facilities are normally sited in remote locations at the airport, far from where the aircraft receive their fuel. So, transfer fuel lines often pass under aircraft runways or taxiways. This is a significant factor when piping is installed or repaired.
After all, how is jet fuel stored? Under the right conditions, Jet fuel can be stored for years and sometimes in very unusual tanks, such as caves underground. Similar to Avgas, there is the risk of gum formation due to oxidation from air. To control this, effect antioxidants – special chemical additives in carefully limited amounts – are used.
Though, where is the fuel stored in a 737?
The main tanks each hold 17,258 lbs of fuel (2,576 gals) and are contained entirely within the wings. FIGURE 1. BOEING 737-700 AIRCRAFT 2.1. 1.1 Air Cycle Machines.
Do planes dump poop?
Aircraft lavatories typically store sewage in tanks, to be disposed off after the plane has landed. However, on the rare occasion that excrement does leak from a plane, it normally freezes instantly due to the cold temperatures at cruising height.
According to the report, the middle seat in the back of the aircraft (the rear of the aircraft) had the best position with just 28% fatality rate. In fact, the worst part to sit in is actually on the aisle of the middle third of the cabin as it comes at a 44% fatality rate.
Fuel is stored in the wings for primarily 3 reasons : Fuel acts as a counter stress for the wings shortly after takeoff when the great stress of the aircraft's mass acts on them. This prevents a large change in the wing dihedral angle. ... The weight of the fuel provides rigidity to the wing, thereby reducing wing flutter.
Over-the-wing refueling is accomplished by opening the fuel tank cap on the upper surface of the wing or fuselage, if equipped with fuselage tanks. The fueling nozzle is carefully inserted into the fill opening and fuel is pumped into the tank.
If Jet A is stored following good QA practices, the sumps are properly located, or in a cone bottom tank, the fuel should last almost indefinitely. If these conditions are not met, then the shelf life can be very short because it depends on what is in the bottom of the tank.
Q: About how much fuel per hour does a medium-sized aircraft such as the 737 burn? A: In round numbers, a 737 will burn 5,000 pounds (750 gallons) an hour. These are approximate figures, and the conversion between pounds and gallons is conservative.
Most trains don't have sewage tanks so anything in the toilet is dumped straight onto the tracks. Human waste is deposited onto the tracks at Paddington station on a daily basis, causing it to pile up and create a disgusting mess.
WiFi in airplanes let you use your gadgets with an internet connection just like on ground, but with the flight mode turned on. ... There are two systems of connectivity for inflight WiFi - Air-to-ground and satellite.
The brace position reduces flailing by having a forward-facing occupant lean over their legs and it reduces secondary-impact injuries by pre-positioning the body against a surface that can be struck. This reduces the momentum of the head and other parts of the body.
“The smoothest place to sit is over the wings,” says commercial pilot Patrick Smith, host of AskThePilot.com. These seats are close to the plane's center of lift and gravity. “The roughest spot is usually the far aft. In the rearmost rows, closest to the tail, the knocking and swaying is more pronounced.”
“The airflow in the cabin from the ceiling to the floor and from the front to the rear may have been associated with a reduced transmission rate,” the study said. “It could be speculated that the rate may have been reduced further had the passengers worn masks.”
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 wet wing is an aerospace engineering technique where an aircraft's wing structure is sealed and used as a fuel tank. By eliminating the need for fuel bladders, aircraft can weigh less and offer improved performance. Wet wings are common among civilian designs, from airliners to small general aviation aircraft.
The C-5 was built to carry more cargo than any other plane. The C-5M can lift more than a quarter million pounds, and the approximately 34,000-cubic-foot cargo bay is large enough to contain one tank, six helicopters, or 24,844,746 ping pong balls.
Can you smoke on a private jet? The short answer is yes, although whether or not you can on a specific aircraft is determined on a case by case basis. ... If your preference is to enjoy a cigar, pipe or cigarette while you are in flight, we will arrange for an aircraft that allows smoking.
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.
During a normal flight, the plan is to burn fuel so the plane's weight will below that number by the time it lands. ... Some airplanes – usually larger ones – have the capability to dump fuel to reduce the landing weight. Dumping fuel can reduce the weight quickly, dumping thousands of pounds in a few minutes.
