How do planes fly? This question arises in the minds of many. The aircraft (AIRCRAFT) ascended into the sky through the ‘lift’ method. Modern aircraft have four main parts except the fan. (1) body or fuselage, (2) control surface, (3) propeller, (4) tail or tail. The tail part and the wings help the aircraft to move up and down, the propeller moves forward and the body carries all kinds of loads.
Modern AIRCRAFT jets do not have propellers. So how does an airplane fly? It moves according to Newton's third law of motion. Its long tube is filled with air, which is expelled in a narrow way. Modern jet-aircraft ram jet, prop jet, turbo jet are three types. Rockets are a lot like jet-planes, but they have their own oxygen inside, they don't have to supply air from outside like jets.

Ordinary planes or jet planes have to move a little on the ground to get to the sky. This requires a runway aerodrome.

But this is not necessary in the case of a helicopter called a helicopter, because the helicopter flies directly from the ground. It does not have a propeller but instead has a fan attached to the head of the aircraft. This fan is called rotor. The ancestor of the helicopter is the autozyro aircraft built in 1923 in Sierra, Spain. It also had a propeller and a fan on top. On the water, on the ground, Akshei not only stopped the movement of people, they also entered the abyss. In ancient times we got the idea of the underworld, we read about the movement of people there. Even today, people have entered the lonely abyss for ease of movement. The brightest example of which is the subway.
Following in the footsteps of Sir Mark Insbard to build a railroad on the bottom of the River Thames in London in 1833, subways and subways have sprung up in 48 countries, including Paris, Moscow, Madrid, Tokyo, New York, Philadelphia and even Calcutta.

In this way, people have taken one step after another in the construction of vehicles to improve their travel, freight and communication. They have even been able to fly in space by making advanced spaceships !!!
HELICOPTER discovery
Now that we know how to fly a plane, we will know how to invent a helicopter. People were not satisfied after the discovery of the airplane. Because, when flying an airplane, he has to fly in several places first. Then it has to fly. Besides, it is not possible for an aircraft to remain stationary in the sky.
The biggest thing is that the plane needs a huge space to land there. So people started planning to build airplanes to take off in less space. Then a new type of aircraft was made. Its name is Helicopter. Its quality is that it takes up very little space to get up and down.

All other aircraft can fly in the sky after a short run. And even after landing, they have to run a little on the ground. But the helicopter can go up and down steeply. For this, it has a huge fan at its very head - it rotates parallel to the ground - it is called Rotor and the wing of an airplane is at its head, it rotates from top to bottom - it is called Propeller. Helicopters can do a few more things. Helicopters can stand in one place in the sky, can go to the side, can even retreat !!!
Rocket (ROCKET) invention
After the invention of the AIRCRAFT, people started trying to figure out how to fly faster in the sky. The speculation of rocket creation began to know how to fly a rocket or an airplane. However, there is disagreement as to exactly when this rocket was tried. Some say that the first rocket was used in the war with the Mongols in 1232 AD. But it was a low-speed rocket. Then, in the early nineteenth century, the British scientist Sir William Congreve made many advances in rockets. It is said that the English used rockets against Napoleon the Great of France. However, after the First World War, good research on rockets began. Dr. of America. Hutchings Goddard made a large aluminum balloon when he was only fifteen years old. The balloon, however, did not fly far.

The force of gravity came down to the ground shortly after. Yet Goddard did not give up. He learned to read and write with his mind and became a professor in college. He then did his doctorate. In 1929, his rocket was launched into space. But people were frightened by the loud sound of the rocket. Goddard then moved to New Mexico with some colleagues. There he built a new kind of rocket, the belly of which was like a huge net. Lots of fuel was poured into it. The fuel was set on fire. The burning of the fuel created a huge gas pressure inside the rocket. That pressure helped the rocket to ascend at high speed.
