Modern airplanes are truly marvels of aircraft engineering to overcome turbulence and unpredictable air in the air and complete the flight with a variety of complex maneuvers, have you ever thought about how a pilot can do this or what happens to the aircraft when the pilot operates certain controls, in this article we will explore how airplanes fly and how pilots can control airplanes in a logical, yet simple way we thank sim scale for lending their cfd support and making this video more informative.
First let's take a closer look at the wings and tails of modern airplanes, one of the interesting things you will notice is that the wings and tail are not made as a solid unit. -the difference is that these wings form a structure that is very specialized in fluid mechanics, namely the shape of the air foil.
Only by understanding the physics behind this simple shape you will fully understand the physics of airplanes, let's look at more about air foil, an air foil produces lift when moved relative to the air this lift allows an airplane to fly how this lift is produced, Erwin produces dong boss as shown.
This causes a pressure difference at the top and bottom of the foil water, and then produces a high quality lift. This cfd analysis is performed using sim scale software which clearly illustrates this fact to know more about foil technology please see our detailed video on air foil, in detail. In general, the higher the angle of attack, the bigger the boss and the greater the airspeed lift also increases the lift significantly
Interesting in the first successful human flight the raid flight also utilizes the same file principle, although their air points are in the form of a simple curve it is enough to produce a good boss road more specifically their plane has two air foils, one more idea to increase lift is By changing the shape of the air foil like this, the deformation will definitely increase and wash and my area thus providing greater lift.
In short there are three techniques to increase the lift of air foil let's apply the knowledge of this file to the plane if we activate flash and slate it will increase and wash and increase lift, ailerons can move up and down and for that reason lift can decrease and increases sequentially, at the tail of the plane you can see the two assessments of the rudder and the elevator.
You can control the vertical force on the tail by adjusting the elevator, by adjusting the rudder you can control the horizontal force, now let's get into the most interesting part of the video controlling the plane using my simple statement ilu let's start with the take off part of the flight to make the plane take off from the ground all you have to do is increase the lift using various techniques and make sure the force is more than the pull of gravity.
The pilot applies all of his three elevator enhancement techniques together to produce takeoff, firstly the aircraft speed is increased by increasing engine thrust when the aircraft speed is high enough the pilot activates the flash and the lift slides increase due to this, when the aircraft is ready to take off they activate live up the tail force tilt the plane as shown and the angle of attack of the air foil will increase.
The factor suddenly increases due to this and aircraft takeoffs are usually maintained at fifteen degrees for takeoff, in this discussion we are talking about engine thrust, but how engines are capable of generating thrust in modern airplanes using a special type of engine called a turbofan engine, to doing so in this case the fan reaction and the reaction force from the exhaust provide the necessary thrust by burning more fuel the pilot can gain more thrust.
Aircraft fuel is stored in me, after the next takeoff appears nail phase of the plane as long as the engine thrust exceeds the drake, the plane's speed will continue to increase the greater the speed the higher the lift, this will cause the plane to rise when the plane reaches the level of flight it will not If there is an acceleration or change in altitude, you can see that under these conditions the thrust must match the drake and the lift must match the weight of the aircraft.
Now let's discuss the most important part, how the plane changes direction, you might think you can do it just by adjusting the rudder, then generating a horizontal force, and this force can rotate the plane but a direct change of direction will cause inconvenience to the passengers and it is not a method practically, to make the turn as shown all you need is centripetal force.
Let's see how the pilot does this centripetal force, the pilot only raises one electron and lowers the other aileron, the difference in traction will make the airplane roll or in this rolling condition the elevator is not vertical, the horizontal component of the elevator can provide the necessary centripetal force to the plane bank.
In this way the pilot can make a change of radius depending on the roll angle and speed of the aircraft but this bang technique has some drawbacks when you hold one electron and the other element down the drag or drake induced on me is not the same, this will cause the plane to wobble this phenomenon is known As an advance sway, the rudder must be operated simultaneously to prevent swaying add others.
the way the pilot controls my various friends and the entire plane is illustrated in this animation, in practice the computer accurately controls all of my friends using the fly by wire system, to lower the plane what the pilot does is reduce engine thrust and keep aircraft noise down, this is the opposite of the ascending operation, when the aircraft loses speed the aircraft is ready to land
At this stage the lab and slides are activated again, this device also increases the drag, to increase my drake statement called spoiler is also activated, the pilot uses one more trick here to reduce the stopping distance which is a back thrust, here the engine cover is wide open and air which should have been forcibly recoiled was directed forward, this would obviously result in a back thrust and would make stopping the aircraft easier.
The cfd simulation we see in this video is produced by sim scale software f b and c f on a powerful cloud based computing, to perform complex cfd analysis using your normal laptop or pc just create a free community and explore please check the description thank you.
