How much is a Jet PlaneWhat does a jet cost?
What is the amount of petrol an aircraft consumes to travel internationally?
An aircraft like a Boeing 747 consumes about 1 gal of petrol (about 4 liters) per second. During a 10-hour journey, it could incinerate 36,000 gal (150,000 liters). The 747 consumes about 5 galons of gas per kilometre (12 litres per kilometre), according to Boeing's website.
However, keep in mind that a 747 can accommodate up to 568 persons. Let's call it 500 persons to take into consideration the fact that not all places are taken on most flight schedules. One 747 transports 500 passengers 1 kilometer with 5 gal of gasoline. This means the plane burns 0.01 gal per passenger per mile.
Meaning the plane gets 100 leagues per gal per person! Typically the auto gets about 25 mile per gal, so the 747 is much better than a single passenger auto, and low -cost comparisons, even if there are four passengers in the auto. That' not too bad considering that the 747 flies at 900 km/h (550 mph)!
So why do jet aircraft need such a long take-off and landing strip to get off the floor?
Minor aircraft do not require a very long take-off and landing strip. To better comprehend this, you have to comprehend how a plane is taking off. Because of the airfoil of the wings an aircraft can take off. It is the airfoil that generates the buoyancy power. The buoyancy power is produced with the velocity.
You need a long airstrip to get you up to airspeed. Here is a photo to show that buoyancy is produced. Identifies this type of extrusion as a extrusion. As you can see, the upper part of the section has a greater curve than the lower part. For this reason this buoyancy is produced.
Once the profile is crossed, the profile is divided into two parts, one at the top and one at the bottom. As a result, a low pressure/suction is generated at the top and similarly, a high compression is generated at the bottom of the profile. Strong downward pressures on the underside push the profile upwards, resulting in a Lifestyle uplift.
Hopefully this will clarify how buoyancy is generated. Well, for all this to be possible, the plane must be moved forward at a certain velocity, and this is achieved by using a take-off and landing area. A certain velocity exists at which the generated buoyancy is greater than the plane's mass.
These speeds are different for different aircraft. These differences depend on the profile's form and mass (there are different kinds of profiles). Previous image is form of general profile).
