on video Types of aircraft engines and propulsion systems

In this video you will see the different types of engines and propulsion systems used for airplanes, my favorites: turbojet, turboprop, turboshaft and turbofan. You will also see the Ramjet engine.

I love the sound of a turbine starting up, the engineering involved, engines and aircraft propulsion systems in general, and you're here because you love it too. An aircraft can be propelled and pushed/pulled forward in many ways, starting with a conventional propeller aircraft that can be moved using a piston or turboprop engine, at the same time there are 'other means like an electric motor, human-powered and even smoking.
Since the myth of Icarus, in which he makes his wings out of bird feathers and flies, men have been trying to understand how certain species take flight in order to reproduce it with machines. Leonardo da Vinci developed the first concepts in the 16th century. But at the time, the only known driving force was that of human muscles. The fundamental principles that would later help to understand how airplanes fly would not appear until the 17th and 18th centuries, with scientists like Newton and Bernoulli. In the 19th century, the industrial revolution allowed the development of many technical advances. The French Clément Ader is the first to take off a plane with a steam engine, inspired by a bat. About ten years later, the Wright brothers made the first controlled and motorized flights in history, in 1903.
Air is sucked in by a blower, then permanently compressed; it then passes into a combustion chamber where it reacts with kerosene and ignites. The reaction caused will expand the gases; these are then projected backwards by a nozzle, which causes the plane to move forward. The gases come out at very high speed as they pass through a reactor whose shape is shrinking.

In addition, on leaving the reactor, the gases rotate a turbine, located on the same axis as the compressor, just after the combustion chamber. The movement of the turbine thus causes that of the compressor and this allows the reaction to take place continuously. The plane is moving and the air flowing over its wings makes it fly.

Airlines are constantly trying to improve the performance of combustion chambers to reduce aircraft emissions 

In the 17th century, Newton stated three fundamental laws to explain motion. The first is the principle of inertia, the second the principle of dynamics. The one that interests us is Newton's third law, the principle of reciprocal actions.
Jet propulsion is indeed based on this principle of action-reaction, which says that for every action, there is an equal and opposite reaction. Thus, the air ejected backwards will exert an equal and opposite force on the aircraft by throwing it forward. This force is called thrust. In addition, the higher the speed of the propelled gas jet, the greater the thrust.Newton's law also makes it possible to explain how airplanes fly; if the wing exerts a force on the air (its weight, force which will make the bottom), then the air exerts an opposite force on the wing, called lift (up). Compensating for these forces helps keep the plane aloft.
