Jet Plane Fuel Consumption:  Jet engine capacity is not measured in CC (cubic centimeters) like car engines because it works differently from internal combustion engines. Jet engines primarily measure thrust (pushing power). For example, a large commercial jet engine (such as the Boeing 777's GE90 engine) can produce a thrust of 110,000 pounds-force. Instead, the CC measurement of a car engine indicates its size and capacity, while a jet engine's capacity is measured by its thrust and power.

As far as mileage is concerned, jet planes give very low mileage. For example, the average mileage of a large aircraft (such as Boeing 747) is 0.2-0.3 kilometer per liter. A Boeing 747 can burn 10-12 liters of fuel every second, which means thousands of liters of fuel can be consumed on long flights.

As far as mileage is concerned, jet planes usually give a mileage of 0.2 to 0.3 kilometer per liter (2-3 liters per kilometer), which sounds very low, but the plane carries many people over long distances, so the consumption per person is not much. The fuel consumption of a large aircraft is huge, for example a Boeing 747 can burn up to about 12 liters of fuel per second, which means that a long flight can consume thousands of liters of fuel.

How does a jet plane engine work? 

The engine of a jet plane is called a jet engine, and its working method is quite complex and powerful. To put it in simple terms, a jet engine works primarily on Newton's third law: "For every action there is an equal and opposite reaction." This means that when the mixture of air and fuel is accelerated backwards from the engine, the plane moves forward. Let's understand step by step:

1. Intake of air

When a jet engine works, large fans attached to its front draw in air. This air enters the engine. The greater the amount of air, the more power the engine can produce.

2. Compressor

After drawing the air, it reaches the compressor located in the front part of the engine. The compressor compresses the air by passing it through small and narrow paths, which increases both the pressure and temperature of the air. The compressed air is now ready for combustion.

3. Combustion

The compressed air now enters the combustion chamber, where it is mixed with fuel (often kerosene or jet fuel). This mixture is burned, and the burning process produces a lot of heat and energy. This heat expands the air rapidly and pushes it backward.

4. Turbine

When hot and rapidly expanding air passes through the rear of the engine, it turns the turbine blades. The turbine's job is to use a portion of this energy to drive the engine's fan and compressor, so that the process continues.

5. Exhaust

Finally, the hot air comes out from the back of the engine at a very high speed. This fast moving air works to push the plane forward.

In a jet engine, air is drawn in, compressed, burned with fuel, and then a turbine is rotated to propel the plane forward. This process continues like a cycle, causing the plane to fly.
