Hello guys, I'm Daniel, writing here this time to explain a question that for a long time I asked myself: What explains the fly of airplanes? This question got better my understanding about the subject in my mind before I have read an article that answered this . So, I want to show for you what I've learnt from this reading, sharing with all of you here and now my observations about the airplane flying and, of course, making clear for who doesn't know the motivation for the aircrafts fly, the reasons beneath that event.
So, let's get to work!
As far as I read, any airplane needs four basic forces in order to keep itself flying . These forces are: DRAG, THRUST, LIFT and WEIGHT.
The drag is a force we can say that works against the airplane's trajectory making it slow down. It's the opposite force to the thrust, causing both together the flying of the airplane.
The thrust is an importan force as well, making the airplane move forward. The airplane gets this force when it blows air from its engines backwards.
The weight force, is an obvious force like its denomination suggests for us when reading it. It's a force responsible for keeping the airplane neither bended down from the front or back.
Lastly, we can mention the lift. The lift is a force that pushes up the airplane. You know, airplanes are made in a such way the air move around its wings. So, as the air moves around the wings and under it, it gets enough lift to take off.
So, I hope you guys have known a little bit more about airplane's running through my little post, and see ya next time!
Comments
Thanks to all the comments here, I'm thankful to all of you indeed! So, Mr. Sowrian is a nice idea I put my voice record here. I will try to put it in action from now on! To begin with, follow my voice record for this post above. BTW, sorry for the misspelled "readed". Definitely is a non-existant word in the English vocabulary. Hugs for all you, bye bye!!!
Hi there,
What makes an aircraft fly is really an interesting phenomena. I agree that to make the aircraft fly we must apply some sort of forces: One force to move it forwards [thrust - generated by an engine pusshing air backwards at great speed]and another force to lift it from the ground [lift force generated by airfoils (wings) of special profile. Drag and weight are negative forces which tend to keep the aircraft ground bounded.
If we mount a thrust engine to a table door it won't fly...not for long...as it needs a lifting force gernerated by an airfoil such as a wing which has a specific shape. The upper surface of the wing is convex [bent upwards] and the bottom sorface is either flat or slightly concave [bent inwards]. The air moving along the upper surface has a longer road to travel, so its speed is faster than the air travelling along the bottom surface of the wing: this way a vacuum is formed and we get an upwards lift as the wing is sucked upwards, putting it in a very simple way.
Gliders don't have an engine giving the thurst force, yet they fly. The helicopter's engines do not give direct thrust force. That's why I think what makes an aircraft airborn is so intriguing.
By the way, if you haven’t heard Daniel’s spoken English before, this is his voice recording that he posted HERE.
Isn't he great?
Hi, Daniel!
I would like to add one more thing to what noaslpls said about the verb 'read'. I hope she doesn't mind!
Both the present tense and past tense of the the verb 'read' are , as pointed out by noaslpls, written exactly the same - READ. However, they differ in pronunciation from each other! You can listen to their pronunciations HERE.
By the way, can I make a suggestion? Perhaps in future you could add your voice recordings on all your blogs. That would be killing two birds with one stone. It's a undeniable fact that your reading/spoken English is outstanding. Let me tell you this, Daniel! I sincerely feel that you could be a role model to many EC members who aspire to speak flawless English. Please check my first VOICE BLOG to get some rough idea how you could turn your normal blog into a voice blog. cheers!
It seems so simple, but I'm sure it's more complicated than that. LOL.
By the way, the past tense of read is still 'read' and not 'readed'
