Little Engineer's Diary: what a beatiful kamikaze :D

Hey hey!!

Now, I'm going to tell you about jet engines. Because I drew a simple jet engine in AutoCAD 3D. Before talk about the drawing, we must talk about what is mechanism of jet engines.

The jet engine squeezes the air from the atmosphere and burns it with fuel. This produces a pushing force in the reverse direction by rapidly blowing out the gases resulting from the heating. With this force, the vehicle to which the motor is connected is allowed to move. These motors have been developed in accordance with Newton's laws of motion. According to this law; Each effect produces a response of equal magnitude and reversal.

If you ask the question of what is the power to fly, we immediately say engine. This answer is correct but incomplete. There are many factors that push it forward. The movement of a plane is basically by increasing the momentum. The mentioned momentum increase is provided by these:

By compressing a turbojet engine air first and then expanding it by heating,
By accelerating the air backward with a propeller,
Modern, high by-pass turbojet engines are obtained partly by expansion in the turbine and partly by propeller speeding.

Propeller transforms the mechanical energy produced by the internal combustion engine or the turbo engine to pulling force by the way of the air mass accelerating in the direction opposite to the direction of the aircraft. The propeller is actually a straight or sprung wing section (airfoil). The reason for being twisted and thinning is to create a uniformly distributed thrust throughout the propeller. Because the flow of air flows over the propeller, its maximum velocity is at the tip. In this case, when a fixed section propeller is used at high speed, it causes major problems at the tip.*

Okey. Now we can look my drawing.
