Air India flight going from Delhi to Mumbai had to return due to engine failure.
An Air India plane has made an emergency landing. On Monday (22 December), the engine of flight AI887 from Delhi to Mumbai stopped immediately after takeoff. As a result, he had to land back in Delhi itself. The plane had two engines, and a safe landing was made after one of them malfunctioned. An aircraft engine is not just an engine. Hundreds of parts together give power to the engine, in which some parts play a very important role.
The jet engine pushes the plane forward and the plane accelerates on the runway. As its speed increases, air comes out faster from the wings. This creates more pressure downwards which pushes the plane upward. This is the reason the ship rises in the air.
How does a plane fly?
The report of the American space agency NASA says, the engine draws air with the help of a fan installed at the front of the aircraft. The compressor increases the air pressure. The compressor is made up of several blades connected to a shaft. This blade rotates at high speed and compresses the air. Fuel is sprayed into the air and produces an electrical spark. The burning gases expand and exit through a nozzle located at the rear of the engine.
As the gases escape backwards, they push the engine and the aircraft forward. This is called thrust. This is the force that pushes the engine forward and thus propels the aircraft forward. Sir Isaac Newton discovered that “for every action there is an equal and opposite reaction.”
The engine follows this principle. The engine takes in large amounts of air. The air is heated. By mixing jet fuel in the air, the temperature of the air can increase up to three thousand degrees. Wind power is used to rotate the turbine. Finally, when the air exits, it pushes backward away from the engine. Due to this the plane moves forward. The wind pushes the plane upward, as a result the plane takes flight.
Now the question is why the plane does not fall in the air? The answer is that the plane moves very fast and the wings keep pushing the air downwards continuously. In this way the situation of lifting it remains intact. When the engine cannot do this and the plane starts descending.
Which part of the engine does what?
- Fan: The fan is the first part of the turbofan installed in the aircraft. The large rotating fan draws large amounts of air. Most of the fan blades are made of titanium. It increases the speed of wind.
- Compressor: This is the first part of the engine. It is made up of many feathers. It has many blades. It works to increase air pressure by drawing air. From here the air is sent to the combustion chamber.
- Combustor: In this part, air is mixed with fuel and a spark is produced in it. It has about 20 nozzles to spray fuel in the air. The mixture of air and fuel catches fire. This produces air with high temperature and high energy. The fuel burns with oxygen present in the air, producing hot and expanding gases. Its temperature can reach up to 2700 degrees.
- Turbine: High temperature air works to rotate the turbine. Finally, when the air exits, it pushes backward away from the engine. Due to this the plane moves forward. The wind pushes the plane upward, as a result the plane takes flight.
- nozzle: The nozzle is that part of the engine which works to give speed to the aircraft. The air passing through the turbine and the cooled air passing through the engine core create a pressure as it exits the nozzle that propels the aircraft forward. Due to which the plane gets speed.
